| ulnar veins | Venae comitantes of the ulnar artery, continuing from those of the supericial palmar arch and joining with those of the radial artery to form the brachial veins in the cubital fossa. Synonym: venae ulnares. (05 Mar 2000) |
| abducens eminence | Prominent portion of the medial eminence, just rostral to the medullary striae in the rhomboidal fossa; it is formed by the internal genu of the facial nerve and the abducens nucleus around which the facial fibres curve. Synonym: colliculus facialis, abducens eminence, eminentia abducentis, eminentia facialis, facial eminence, facial hillock. (05 Mar 2000) |
| arcuate eminence | A prominence on the anterior surface of the petrous portion of the temporal bone indicating the position of the superior saemicircular canal. Synonym: eminentia arcuata. (05 Mar 2000) |
| articular eminence of temporal bone | Articular eminence of the temporal bone which bounds the mandibular fossa anteriorly; it forms the anterior root of the zygomatic process; it is enclosed by the articular capsule of the temporomandibular joint with the articular fossa; the head of the mandible (and intervening articular disc) move onto the articular tubercle to allow full depression of mandible (opening of mouth). Synonym: tuberculum articulare ossis temporalis, articular eminence of temporal bone, eminentia articularis ossis temporalis, tuber zygomaticum. (05 Mar 2000) |
| canine eminence | An elevation on the maxilla corresponding to the socket of the canine tooth. Synonym: canine prominence. (05 Mar 2000) |
| radial eminence of wrist | A rather large flat eminence on the radial side of the palmar aspect of the wrist, due to the tuberosity of scaphoid and the ridge on the trapezium. Synonym: eminentia carpi radialis. (05 Mar 2000) |
| genital eminence | In very young embryos, the vaguely outlined median elevation immediately cephalic to the proctodeum; its central part develops into the genital tubercle. (05 Mar 2000) |
| parietal eminence | A prominent portion of the parietal bone, a little above the centre of its external surface, usually corresponding to the point of maximum width of the head. Synonym: tuber parietale, eminentia parietalis, parietal tuber. (05 Mar 2000) |
| maxillary eminence | The bulging lower extremity of the posterior surface of the body of the maxilla, behind the root of the last molar tooth. Synonym: tuber maxillae, eminentia maxillae, maxillary eminence. (05 Mar 2000) |
| medial eminence | Longitudinal elevation of the rhomboid fossa, extending along either side of the midline throughout the length of the rhombencephalon; made up of named elevations such as the facial colliculus and the hypoglossal and vagal trigones. Synonym: eminentia medialis, eminentia teres, funiculus teres, round eminence. (05 Mar 2000) |
| median eminence | <anatomy> Raised area on the infundibular hypothalamus at the floor of the third ventricle of the brain which contains the primary capillary network of the hypophyseal portal system. (12 Dec 1998) |
| restiform eminence | A prominence of the dorsolateral surface of the medulla oblongata corresponding to the larger lateral part of the inferior cerebellar peduncle. Synonym: eminentia restiformis. (05 Mar 2000) |
| round eminence | Longitudinal elevation of the rhomboid fossa, extending along either side of the midline throughout the length of the rhombencephalon; made up of named elevations such as the facial colliculus and the hypoglossal and vagal trigones. Synonym: eminentia medialis, eminentia teres, funiculus teres, round eminence. (05 Mar 2000) |
