The valleculae can collect saliva to prevent initiation of the swallowing reflex. The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
Plummer–Vinson syndrome (also known as Paterson–Kelly syndrome [1] or Paterson–Brown-Kelly syndrome in the UK [2]) is a rare disease characterized by dysphagia (difficulty swallowing), iron-deficiency anemia, glossitis (inflammation of the tongue), cheilosis (cracking at the corners of the mouth), and esophageal webs (thin membranes in the esophagus that can cause obstruction). [1]
Swallowing unusually large objects or placing objects in the back of the mouth may cause the pharyngeal reflex. Some people, for instance sword swallowers , have learned how to suppress it. [ 1 ] In contrast, triggering the reflex is sometimes done intentionally to induce vomiting, by those who have bulimia nervosa .
Swallowing, also called deglutition or inglutition [1] in scientific contexts, is the process in the body of a human that allows for a substance to pass from the ...
Like in humans, it functions to prevent entry of food into the trachea during swallowing. [17] The position of the larynx is flat in mice and other rodents, as well as rabbits. [ 4 ] For this reason, because the epiglottis is located behind the soft palate in rabbits, they are obligate nose breathers, [ 18 ] [ 19 ] as are mice and other rodents ...
Achalasia is a major exception to usual pattern of dysphagia in that swallowing of fluid tends to cause more difficulty than swallowing solids. In achalasia, there is idiopathic destruction of parasympathetic ganglia of the Auerbach's (Myenteric) plexus of the entire esophagus, which results in functional narrowing of the lower esophagus , and ...
The half-swallow boom allows for a repositioning of the vocal folds by taking advantage of laryngeal positioning when swallowing. The client is asked to take a breath and then initiate the movement of swallowing, followed by forcefully saying "boom". When performed properly, the "boom" sounds loud and clear.
There may be difficulty breathing, dysphagia (difficulty swallowing), or dyspepsia (discomfort in the upper abdomen), especially if the cyst becomes large. [citation needed] The most common location for a thyroglossal cyst is midline or slightly off midline, between the isthmus of the thyroid and the hyoid bone or just above the hyoid bone. A ...
