Musculus uvulae

Musculus uvulae is a muscle that helps in the functioning of the human body. It is a part of the soft palate in the human mouth. The musculus uvulae is responsible for the elevation of the uvula, a small, bell-shaped structure located at the back of the throat.

Anatomy

The musculus uvulae is a paired muscle that arises from the posterior nasal spine and the palatine aponeurosis. It extends into the uvula and intermingles with the muscular fibers from the opposite side. The muscle is innervated by the pharyngeal plexus of the vagus nerve.

Function

The primary function of the musculus uvulae is to elevate the uvula. This action helps in closing off the nasopharynx during swallowing and speaking, preventing food and liquid from entering the nasal cavity. It also plays a role in the articulation of certain sounds in speech.

Clinical significance

Abnormalities or damage to the musculus uvulae can lead to conditions such as uvula edema or velopharyngeal insufficiency. These conditions can affect swallowing and speech, and may require medical intervention.
