| external iliac artery | <anatomy, artery> Origin, common iliac; branches, inferior epigastric, deep circumflex iliac; becomes the femoral at the inguinal ligament. Synonym: arteria iliaca externa. (05 Mar 2000) |
|---|---|
| external iliac lymph nodes | Nodes located in association with the external iliac vein; they are subdivided into three groups: intermediate external iliac lymph nodes, between the vein and the external iliac artery; lateral external iliac lymph nodes, and medial external iliac lymph nodes, medial to the vein; they all receive afferent vessels from the inguinal nodes, lower abdominal wall, and pelvic viscera, and send efferent vessels to the common iliac nodes. Synonym: nodi lymphatici iliaci externi. (05 Mar 2000) |
| external iliac plexus | A lymphatic plexus formed by the lymph nodes along the external iliac artery on either side, and their afferent and efferent vessels. Synonym: plexus iliacus externus. (05 Mar 2000) |
| external iliac vein | <anatomy, vein> A direct continuation of the femoral vein superior to the inguinal ligament, uniting with the internal iliac vein to form the common iliac vein. Synonym: vena iliaca externa. (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) |
