| cupula cristae ampullaris | A gelatinous mass that overlies the hair cells of the ampullary crests of the saemicircular ducts; movement of endolymphatic fluid causes the cupula to move across the hair cells of the ampullary crest. Synonym: cap of the ampullary crest. (05 Mar 2000) |

| crista ampullaris | An elevation on the inner surface of the ampulla of each saemicircular duct; filaments of the vestibular nerve pass through the crista to reach hair cells on its surface; the hair cells are capped by the cupula, a gelatinous protein-polysaccharide mass.

| nervus ampullaris lateralis | <anatomy, nerve> A branch of the utriculoampullar nerve that supplies the crista ampullaris of the lateral saemicircular duct. Synonym: nervus ampullaris lateralis. (05 Mar 2000) |
| nervus ampullaris posterior | <anatomy, nerve> A branch of the vestibular part of the eighth nerve that supplies the crista ampullaris of the posterior saemicircular duct. Synonym: nervus ampullaris posterior. (05 Mar 2000) |
| sulcus ampullaris | The groove on the external surface of the ampulla of each saemicircular duct where the nerve enters the crista ampullaris. Synonym: sulcus ampullaris. (05 Mar 2000) |
| ala cristae galli | A small lateral expansion of the ethmoid bone from the front of the crista galli on each side that articulates with the frontal bone and forms the foramen caecum. Synonym: ala cristae galli, alar process. (05 Mar 2000) |
