Uvula

 

(also palatine uvula), a cone-shaped extension of the soft palate in humans and some anthropoid apes. The uvula departs from the middle of the posterior margin of the palate and proceeds with the apex downward. It is covered by a mucous membrane. The anterior side of the uvula faces the mouth, and the posterior side the nasopharynx. The uvula has its own tensor and levator muscles. When food reaches the throat and comes into contact with the uvula, the latter, along with the entire soft palate, rises by reflex action and thus enables the food to pass from the mouth into the pharynx. The human uvula also aids in hermetically sealing the mouth to prevent the jaw from sagging when the body is vertical. Parts of the oral appendages of different origins in some arthropods (crustaceans, arachnids, and insects) are also called uvulas.

With the help of its internal muscular fibres, the uvula also aids the soft palate in sealing off the passageway between your throat and your nose when you swallow and speak, helping to make sure bits of food or liquid don't go up your nose and that the air and vocal vibrations are directed out of your mouth and not your nostrils.
Some other people ask for its removal because they feel that the uvula is too long.
Furthermore, there is a small group of patients who show symptoms suspicious of PTA such as trismus, uvula edema, and swelling of the arched palate.

Unilateral cases exhibit asymmetry of tonsils and palate, uvula deviation, and unilateral otalgia.
The oropharynx is bounded by the soft palate and uvula superiorly, tongue inferiorly, dentition and buccal mucosa anterolaterally, palatine tonsils and tonsillar pillars posterolaterally, and the posterior pharyngeal wall.
This model includes the tongue body, the hard palate, the soft palate, the uvula, the epiglottis, the posterior pharyngeal wall, and both lateral walls.
Doctors have advised Kejriwal enlarged soft palate and uvula in relation to a slight increase in the volume of the tongue," which means his tongue was too big for his mouth.

In a review of the relevant literature, Mat Saad et al reported that the rare, albeit potentially hazardous, hair- thread tourniquet syndrome was usually observed in penis (44.2%), toes (40%), and fingers (8.57%).6 In addition to these regions, hair-thread tourniquet syndrome may also involve highly unusual regions such as uvula.7 In our patient the syndrome spontaneously developed in a haemangioma, a presentation that was previously unknown.
The most affected anatomical sites included labial mucosa, tongue edge, hard and soft palates, lip commissure, ventral tongue, uvula, and tonsils, respectively.
