Palatine uvula

Palatine uvula

The Palatine uvula, often referred to simply as the uvula, is a conical projection from the posterior edge of the middle of the soft palate, composed of connective tissue containing a number of racemose glands, and some muscular fibers. It is located in the human body's throat.

Anatomy

The uvula plays a key role in the articulation of the sound of the human voice to form the sounds of speech. The mucous membrane of the mouth is continuous with the inner layer of the uvula.

Function

The uvula functions during swallowing and speaking. While swallowing, the palatine uvula moves upwards to close off the nasopharynx, preventing food from entering the nasal cavity. When speaking, it acts to send air out through the mouth instead of the nose.

Clinical significance

The uvula can be implicated in snoring and sleep apnea when an elongated uvula vibrates, causing the loud noise of snoring and the breathing difficulties associated with sleep apnea. Uvulitis is inflammation of the uvula, which can cause a sore throat and difficulty swallowing.
