The uvula is a small, conical, pendulous process projected inferiorly from the midline posterior margin of the soft palate. It is primarily formed from the insertions of the two muscles of the uvula and their covering mucosa.
location: posterior midline soft palate
blood supply: from ascending palatine and pharyngeal arteries
innervation: sensory from the lesser palatine nerve (CN Vb)
The uvula is supplied by branches of the arteries that supply the soft palate:
palatine branch of the ascending pharyngeal artery
The function of the uvula is to contribute to palatopharyngeal closure as part of deglutition 4.
elongated uvula 6,7: is a rare finding that may present with symptoms such as chronic cough and obstructive sleep apnea; recurrent upper airway obstruction by the elongated uvula can also mimic asthma in children; uvulectomy is the mainstay of treatment and is curative
bifid uvula 6,7: up to 2% of the population
History and etymology
