Uvular Muscle (Musculus uvulae)
Educational content only — not medical advice.
Anatomy
The uvular muscle (musculus uvulae) is an intrinsic muscular structure of the soft palate consisting of two parallel longitudinal slips running along the median line of the uvula. Extending from the posterior nasal spine to the mucosal tip of the uvula, it thickens the soft palate to ensure an airtight seal against the pharyngeal wall during swallowing and high-pressure speech consonants.
Origin & insertion
From the posterior nasal spine of the horizontal plates of the palatine bones and the palatine aponeurosis to the mucous membrane of the uvula.
Action
Shortens, thickens, and elevates the uvula, assisting in velopharyngeal valve competence.
Innervation
Pharyngeal branch of the vagus nerve (cranial nerve X) via the pharyngeal plexus.
Clinical notes
A bifid uvula indicates hypoplasia or failure of midline fusion of the paired uvular muscles, serving as a classic clinical clue to a submucous cleft palate.
