| labial vestibule | That part of the oval vestibule related to the lips. (05 Mar 2000) |
|---|---|
| fossa of vestibule of vagina | The portion of the vestibule of the vagina between the frenulum of the labia minora and the posterior labial commissure of the vulva. Synonym: fossa vestibuli vaginae, fossa navicularis vestibulae vaginae, vestibular fossa. (05 Mar 2000) |
| acoustic crest | 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. Synonym: crista ampullaris, acoustic crest, transverse septum. (05 Mar 2000) |
| acousticofacial crest | The part of the neural crest from which the ganglia of the seventh and eighth cranial nerves develop. (05 Mar 2000) |
| alveolar crest | The portion of the alveolar bone extending beyond the periphery of the socket, lying interproximally, the top of the residual alveolar bone. (05 Mar 2000) |
| ampullary crest | 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. Synonym: crista ampullaris, acoustic crest, transverse septum. (05 Mar 2000) |
| anterior lacrimal crest | A vertical ridge on the lateral surface of the frontal process of the maxilla that forms part of the medial rim of the orbit. Synonym: crista lacrimalis anterior. (05 Mar 2000) |
| arched crest | The ridge on the anterior surface of the arytenoid cartilage that separates the triangular from the oblong fovea. Synonym: crista arcuata cartilaginis arytenoideae, arched crest, arcuate crest. (05 Mar 2000) |
| arcuate crest | The ridge on the anterior surface of the arytenoid cartilage that separates the triangular from the oblong fovea. Synonym: crista arcuata cartilaginis arytenoideae, arched crest, arcuate crest. (05 Mar 2000) |
| arcuate crest of arytenoid cartilage | The ridge on the anterior surface of the arytenoid cartilage that separates the triangular from the oblong fovea. Synonym: crista arcuata cartilaginis arytenoideae, arched crest, arcuate crest. (05 Mar 2000) |
| basilar crest of cochlear duct | An inward projection of the spiral ligament of the cochlea to which is attached the basilar membrane forming the floor of the cochlear duct. Synonym: crista basilaris ductus cochlearis. (05 Mar 2000) |
| buccinator crest | A ridge passing from the base of the coronoid process of the mandible to the region of the last molar tooth; it gives attachment to the mandibular part of the buccinator muscle. Synonym: crista buccinatoria. (05 Mar 2000) |
| cap of the ampullary crest | 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) |
| ganglionic crest | A group of embryonic cells that separate from the neural plate during neurulation and migrate to give several different lineages of adult cells: the spinal and autonomic ganglia, the glial cells of the peripheral nervous system and nonneuronal cells, such as chromaffin cells, melanocytes and some haemopoietic cells. (18 Nov 1997) |
| marginal crest | The rounded borders which form the mesial and distal margins of the occlusal surface of a tooth. Synonym: crista marginalis, marginal ridge. (05 Mar 2000) |
