Ampullary cupula
Cupula ampullaris
Definition
The ampullary cupula is a gelatinous body overhanging the hair cells of the ampullary crests of the semicircular ducts; sensory hair cells are immersed in it and movement of endolymphatic fluid causes the cupula to move across the hair cells of the ampullary crest.
