Swallowing , sometimes called deglutition in scientific contexts, is the process in the human or animal body that allows for a substance to pass from the mouth , to the pharynx , and into the esophagus , while shutting the epiglottis.

Swallowing is an important part of eating and drinking. If the process fails and the material such as food, drink, or medicine goes through the trachea , then choking or pulmonary aspiration can occur. In the human body the automatic temporary closing of the epiglottis is controlled by the swallowing reflex. The portion of food, drink, or other material that will move through the neck in one swallow is called a bolus.

However, from the viewpoints of physiology , of speech-language pathology , and of health care for people with difficulty in swallowing dysphagia , it is an interesting topic with extensive scientific literature.

Eating and swallowing are complex neuromuscular activities consisting essentially of three phases, an oral, pharyngeal and esophageal phase. Each phase is controlled by a different neurological mechanism. The oral phase, which is entirely voluntary, is mainly controlled by the medial temporal lobes and limbic system of the cerebral cortex with contributions from the motor cortex and other cortical areas. The pharyngeal swallow is started by the oral phase and subsequently is coordinated by the swallowing center on the medulla oblongata and pons.

The reflex is initiated by touch receptors in the pharynx as a bolus of food is pushed to the back of the mouth by the tongue, or by stimulation of the palate palatal reflex. Swallowing is a complex mechanism using both skeletal muscle tongue and smooth muscles of the pharynx and esophagus. The autonomic nervous system ANS coordinates this process in the pharyngeal and esophageal phases. Upon entering the oral cavity, the mandible elevates and the lips adduct to assist in oral containment of the food and liquid.

Food is moistened by saliva from the salivary glands parasympathetic. Food is mechanically broken down by the action of the teeth controlled by the muscles of mastication V 3 acting on the temporomandibular joint. Buccinator VII helps to contain the food against the occlusal surfaces of the teeth. The bolus is ready for swallowing when it is held together by saliva largely mucus , sensed by the lingual nerve of the tongue VII—chorda tympani and IX—lesser petrosal V 3.

Any food that is too dry to form a bolus will not be swallowed. A trough is then formed at the back of the tongue by the intrinsic muscles XII. The trough obliterates against the hard palate from front to back, forcing the bolus to the back of the tongue. The intrinsic muscles of the tongue XII contract to make a trough a longitudinal concave fold at the back of the tongue. The tongue is then elevated to the roof of the mouth by the mylohyoid mylohyoid nerve—V 3 , genioglossus , styloglossus and hyoglossus the rest XII such that the tongue slopes downwards posteriorly.

The contraction of the genioglossus and styloglossus both XII also contributes to the formation of the central trough. At the end of the oral preparatory phase, the food bolus has been formed and is ready to be propelled posteriorly into the pharynx. In order for anterior to posterior transit of the bolus to occur, orbicularis oris contracts and adducts the lips to form a tight seal of the oral cavity.

Once the bolus reaches the palatoglossal arch of the oropharynx, the pharyngeal phase, which is reflex and involuntary, then begins. Receptors initiating this reflex are proprioceptive afferent limb of reflex is IX and efferent limb is the pharyngeal plexus- IX and X. They are scattered over the base of the tongue, the palatoglossal and palatopharyngeal arches, the tonsillar fossa, uvula and posterior pharyngeal wall.

Stimuli from the receptors of this phase then provoke the pharyngeal phase. In fact, it has been shown that the swallowing reflex can be initiated entirely by peripheral stimulation of the internal branch of the superior laryngeal nerve. For the pharyngeal phase to work properly all other egress from the pharynx must be occluded—this includes the nasopharynx and the larynx.

When the pharyngeal phase begins, other activities such as chewing, breathing, coughing and vomiting are concomitantly inhibited.

The soft palate is tensed by tensor palatini Vc , and then elevated by levator palatini pharyngeal plexus—IX, X to close the nasopharynx. There is also the simultaneous approximation of the walls of the pharynx to the posterior free border of the soft palate, which is carried out by the palatopharyngeus pharyngeal plexus—IX, X and the upper part of the superior constrictor pharyngeal plexus—IX, X. The pharynx is pulled upwards and forwards by the suprahyoid and longitudinal pharyngeal muscles — stylopharyngeus IX , salpingopharyngeus pharyngeal plexus—IX, X and palatopharyngeus pharyngeal plexus—IX, X to receive the bolus.

The palatopharyngeal folds on each side of the pharynx are brought close together through the superior constrictor muscles, so that only a small bolus can pass. The actions of the levator palatini pharyngeal plexus—IX, X , tensor palatini Vc and salpingopharyngeus pharyngeal plexus—IX, X in the closure of the nasopharynx and elevation of the pharynx opens the auditory tube, which equalises the pressure between the nasopharynx and the middle ear.

This does not contribute to swallowing, but happens as a consequence of it. It is true vocal fold closure that is the primary laryngopharyngeal protective mechanism to prevent aspiration during swallowing. The adduction of the vocal cords is effected by the contraction of the lateral cricoarytenoids and the oblique and transverse arytenoids all recurrent laryngeal nerve of vagus. Since the true vocal folds adduct during the swallow, a finite period of apnea swallowing apnea must necessarily take place with each swallow.

The clinical significance of this finding is that patients with a baseline of compromised lung function will, over a period of time, develop respiratory distress as a meal progresses. Subsequently, false vocal fold adduction, adduction of the aryepiglottic folds and retroversion of the epiglottis take place. Retroversion of the epiglottis, while not the primary mechanism of protecting the airway from laryngeal penetration and aspiration, acts to anatomically direct the food bolus laterally towards the piriform fossa.

Additionally, the larynx is pulled up with the pharynx under the tongue by stylopharyngeus IX , salpingopharyngeus pharyngeal plexus—IX, X , palatopharyngeus pharyngeal plexus—IX, X and inferior constrictor pharyngeal plexus—IX, X. The respiratory center of the medulla is directly inhibited by the swallowing center for the very brief time that it takes to swallow.

This means that it is briefly impossible to breathe during this phase of swallowing and the moment where breathing is prevented is known as deglutition apnea. The bolus moves down towards the esophagus by pharyngeal peristalsis which takes place by sequential contraction of the superior, middle and inferior pharyngeal constrictor muscles pharyngeal plexus—IX, X.

The lower part of the inferior constrictor cricopharyngeus is normally closed and only opens for the advancing bolus. The velocity through the pharynx depends on a number of factors such as viscosity and volume of the bolus.

Like the pharyngeal phase of swallowing, the esophageal phase of swallowing is under involuntary neuromuscular control. However, propagation of the food bolus is significantly slower than in the pharynx. The upper esophageal sphincter relaxes to let food pass, after which various striated constrictor muscles of the pharynx as well as peristalsis and relaxation of the lower esophageal sphincter sequentially push the bolus of food through the esophagus into the stomach. Then the larynx and pharynx move down from the hyoid to their relaxed positions by elastic recoil.

Swallowing therefore depends on coordinated interplay between many various muscles, and although the initial part of swallowing is under voluntary control , once the deglutition process is started, it is quite hard to stop it. Swallowing becomes a great concern for the elderly since strokes and Alzheimer's disease can interfere with the autonomic nervous system.

Speech pathologists commonly diagnose and treat this condition since the speech process uses the same neuromuscular structures as swallowing. Diagnostic procedures commonly performed by a speech pathologist to evaluate dysphagia include Fiberoptic Endoscopic Evaluation of Swallowing and Modified Barium Swallow Study. Occupational Therapists may also offer swallowing rehabilitation services as well as prescribing modified feeding techniques and utensils.

Consultation with a dietician is essential, in order to ensure that the individual with dysphagia is able to consume sufficient calories and nutrients to maintain health.

In terminally ill patients, a failure of the reflex to swallow leads to a build-up of mucus or saliva in the throat and airways, producing a noise known as a death rattle not to be confused with agonal respiration , which is an abnormal pattern of breathing due to cerebral ischemia or hypoxia. Abnormalities of the esophagus may lead to esophageal dysphagia.

The failure of the lower esophagus sphincter to respond properly to swallowing is called achalasia. In many birds, the esophagus is largely a mere gravity chute , and in such events as a seagull swallowing a fish or a stork swallowing a frog , swallowing consists largely of the bird lifting its head with its beak pointing up and guiding the prey with tongue and jaws so that the prey slides inside and down.

In fish , the tongue is largely bony and much less mobile and getting the food to the back of the pharynx is helped by pumping water in its mouth and out of its gills. In snakes , the work of swallowing is done by raking with the lower jaw until the prey is far enough back to be helped down by body undulations.

Gulp uvula her throat esophagus stomach. Causes of a Swollen Uvula


Toast is an unlikely agent of death. But there you are in your kitchen on a Saturday morning, inexplicably choking on a mouthful, trying not to panic. The day begins like any other for Samantha Anderson, a goldsmith and mother of three from Brisbane, Australia. She has made her usual breakfast of tea and toast with peanut butter and lets her mind wander as she takes her first bite.

She tries again, pressing her lips together and pushing the food back further in her mouth where her throat can take over. She manages to slowly suck a bit of air past the blockage until she can muster up a forceful cough.

And again. And again, finally dislodging the toast on the third try. She is temporarily jolted by the episode, her heart racing. But it does, over and over.

People who struggle to swallow can easily choke. They can breathe food or water into their lungs and develop aspiration pneumonia, or get so little food to go down the right way that they become dehydrated and malnourished. If it gets bad enough, they may have to switch to a fully liquid diet.

And in severe cases, they may have to survive via a feeding tube inserted through their abdominal wall and into their stomach, as Anderson eventually did for 18 months. Firm statistics on the prevalence of swallowing disorders are also sparse, but a recent survey in the Netherlands estimated that they affect as many as 1 in 8 adults.

Some of the problems derive from esophageal conditions such as acid reflux disease. Others are a consequence of an infection, muscle dysfunction, stroke or advancing age. Hospital neonatal units also routinely see infants struggling to suckle due to prematurity, disease, developmental delay or other disorder. And yet, support groups are rare and the relatively small research community has only recently begun to make significant headway in improving the lot of a largely fragmented and voiceless population.

One gave her Valium for what he assumed was stress. Advocates call dysphagia an invisible disorder and a silent epidemic. The cruelty is compounded by how it distorts eating, which is not only a physical necessity but also a way for our highly social species to bond, relax and savor favorite foods. Researchers are studying an assortment of animals to piece together the signs of a bad swallow.

Put your index finger on the tip of your chin, and slide it down the midline of your neck until you reach the first protruding landmark.

Your soft palate and uvula dangling down from the top close off the upper airway from your nose to your mouth. The mechanism is a necessary remedy for a physiological quirk in mammals: the air and food intake systems cross paths in the throat. Every time you swallow, she says, you momentarily stop breathing until your throat is clear. As your windpipe closes off, your throat expands to receive the delivery from your mouth. A valve at the base of the throat, the upper esophageal sphincter, initially relaxes to allow the tea or wad of bread into the esophagus before contracting again to prevent any backflow.

A coordinated wave of muscle contractions then pushes everything along until it reaches the lower esophageal sphincter. This valve similarly relaxes to empty the contents into the stomach, and then constricts to seal the portal.

Although triggered by different signals from the brain, both actions follow the same general sequence of events, and both can suffer from malfunctions in timing, coordination or strength.

Depending on how clean your mouth is, a milliliter of saliva can contain 1 million to million bacterial cells. To keep the airway clear, young adults spontaneously swallow about once every minute.

This rate slows during sleep and with advancing age or disease. A complete failure of the reflex, however, can cause chronic choking. Therein lies another major problem in acknowledging the havoc wreaked by dysphagia. We associate the breakdown of such a seemingly basic process with the end of life.

It happens in hospitals, sure, and in hospices and beds that will soon be empty. Anderson recalls some of her darkest times, when she would wake herself up in the middle of the night by choking on her own saliva. A good way to make someone self-conscious about eating a blueberry muffin is to arrange a breakfast buffet—with muffins, say, and hard-boiled eggs and cantaloupe and coffee—in a hotel foyer surrounded by ten large video monitors on continuous loop depicting good and bad swallows in all their magnified, high-resolution glory.

On the second floor of the Westin Michigan Avenue hotel in Chicago, attendees at the annual Dysphagia Research Society conference are picking over the remnants of a breakfast buffet while vendors showcase their competing imaging systems.

Others depict a barium swallow, an X-ray-based method in which patients drink a chalky, milkshake-like drink that coats the surfaces of the mouth and throat and can highlight places where the sequence of events is going awry. For Anderson, one of the first clear signs of a process gone haywire came from a barium swallow that suggested she was swallowing long after she should have been, and that the liquid was meanwhile spilling over the back of her mouth and into her throat.

Other tests revealed that she had lost all sensation in the back two-thirds of her tongue. Stick your tongue out between your front teeth and gently bite down on it near the tip. Now hold this position while swallowing hard in quick succession.

To help compensate, speech-language pathologists and other dysphagia experts have developed a repertoire of a dozen or so swallowing exercises to build up strength in the tongue and throat muscles. Studies suggest that the maneuver strengthens the base of the tongue and forces some muscles in the back of the throat to constrict harder to aid the swallow. Other exercise trials have proliferated but, so far, have yielded conflicting evidence. Ditto for electrical stimulation to coax the throat muscles to contract, and researchers such as Rebecca German maintain that we still have much to learn about correcting or minimizing the faulty mechanics of a bad swallow.

Some of that knowledge may emerge from careful observations of animals with similar difficulties. An abnormal licking motion in dysphagia-susceptible mice fed chocolate syrup, for example, may provide an early sign of swallowing difficulties; researchers hope the data may benefit people with degenerative conditions. As the dogs eat food of varying consistency in glass-walled kennels, a frame-by-frame video analysis may point out consistent signs of trouble that could help them as well as their human counterparts.

Researchers are even training rats to do tongue exercises in the hope that the increased strength will improve their swallowing ability. Outside of the clinic or lab, however, conveying the seriousness of dysphagia can be surprisingly challenging.

But silent aspiration causes a dramatic rise in pneumonia risk. How then, can the public hope to grasp the magnitude of the problem? Although he may never again get that chance, the year-old Texan is quietly determined to help younger people with dysphagia, such as Anderson, avoid a similar fate.

After being diagnosed with a type of head and neck cancer in , he endured 36 rounds of radiation, eight rounds of chemotherapy and six surgeries. His cancer has recurred four times and twice, doctors gave him only months to live. They removed a chunk of his cancer-infected throat and replaced it with muscle and tissue from his right calf.

They cut away part of his tongue and punched a quarter-sized hole in his soft upper palate to remove other tumors. Life has changed dramatically, however. With so many nerves damaged or removed, he has virtually no control over his swallowing and depends on gravity to guide liquid food safely past his airway and down his reconstructed throat.

For the better part of a decade, he has eaten standing up, in isolation. Trips are especially tricky. For a rare week-long vacation in , to the Virgin Islands, Steger filled a suitcase with 40 pounds of carefully wrapped essentials:. He made similar calculations for his three-day trip to the Dysphagia Research Society conference, where he has become a regular since taking over as president of the National Foundation of Swallowing Disorders in Steger has sought to transform the foundation into an increasingly visible and growing community of patients and caregivers.

In exchange for a donation, attendees can also mix their evening glass of wine with a colourless xanthan gum thickener to get a taste of what a modified diet might be like. Thin liquids, such as water and wine, tend to flow quickly and splash around, meaning that they can easily lead to trouble if the timing of a swallow is even slightly off. Thicker liquids can slow down the process and keep everything moving together. Although in-person dysphagia support groups are still relatively rare and usually linked to nearby speech-language pathology practices, the foundation is working to build a wider network throughout the US.

Patients from around the world have likewise sought out the foundation for crucial advice, support and commiseration. On its website, Anderson and others have shared similar stories of spending hours trying to consume enough calories and remain hydrated, of eating alone to avoid embarrassment or concentrate on swallowing without choking, of becoming isolated even from family members. For many, the sense of loss can be nearly overwhelming, and the aroma of a once-favorite meal can reduce them to tears.

Inside a swallowing disorders support group. The cumulative stress of dysphagia, as researchers are finding, can profoundly degrade the quality of life for both patients and their loved ones. Anderson avoided eating in the same room as her kids to keep them from worrying, but made sure she was always within striking distance of someone who could help in case of a choking emergency.

Eventually, her husband became her spotter for every meal, while friends awkwardly joked that they wanted to be on her diet.

Embarrassed, frightened and famished, she could no longer stand to be around others during mealtimes and even stopped working in her own jewellery gallery.

When doctors finally put her on a feeding tube to halt her spiraling weight loss, she felt full for the first time in months. Angela Dietsch is well acquainted with the strong desire—the desperation, even—that otherwise healthy people with dysphagia have to taste pizza, a doughnut or another reminder of a once-normal life. That leaves the jaw, chin and neck dangerously exposed to battle injuries. For many of these young men and women, the idea that they can never again eat a solid meal with their families is unfathomable.

Xerostomia is caused by decreased saliva flow and can make dysphagia worse. In an experiment exploring whether different tastes might increase saliva flow, Dietsch repurposed taste strips that mimic real foods but dissolve safely on the tongue. For her experiment with the veterans, Dietsch tried strips with glazed doughnut, buttered popcorn, lemon-lime and icy mint flavors.

The veterans began requesting—and fighting over —the strips, including ones flavored like margarita and honey-bourbon.

Some even used them during family dinners. Amazed, she realised that the strips could provide a low-risk strategy for stimulating taste and aiding dysphagia therapy.

The strips also might provide a big psychological lift during communal meals such as Thanksgiving or Christmas. What if one strip was turkey-flavored, another reminiscent of relish, and a third like apple pie?

It might sound ridiculous, Dietsch says. One of the only commercially available options, apart from breath fresheners, is a line of chocolate, watermelon, strawberry and mango tasting strips sold as adult novelties to aid oral sex. The gung-ho year-old, a father of a preschooler and two grown children, remains an avid bicyclist despite a series of accidents that left him with five broken ribs, a titanium plate in his neck, and a surgically repaired right hand.

The radiation therapy that beat back his tonsil cancer also undermined both his swallowing and speaking abilities, once leading a hotel clerk to assume that he was deaf. Others have accused him of being drunk.
