| collateral circulation | Compensatory circulation carried on through secondary channels after obstruction of the principal vessel supplying the part. (12 Dec 1998) |
|---|---|
| collateral digital artery | <anatomy, artery> Terminal branches of the common palmar digital artery that pass to the side of each finger. Synonym: arteria digitalis palmaris propria, collateral digital artery, digital collateral artery. (05 Mar 2000) |
| collateral eminence | A longitudinal elevation of the floor of the collateral trigone of the lateral ventricle of the brain, between the hippocampus and the calcar avis, caused by the proximity of the floor of the collateral fissure. Synonym: eminentia collateralis. (05 Mar 2000) |
| collateral fissure | A long, deep sagittal fissure on the undersurface of the temporal lobe, marking the border between the fusiform gyrus laterally and the hippocampal and lingual gyri medially; the great depth of the collateral sulcus results in a bulging of the floor of the occipital and temporal horn of the lateral ventricle, the collateral eminence. Synonym: sulcus collateralis, sulcus occipitotemporalis, collateral fissure, fissura collateralis, occipitotemporal sulcus. (05 Mar 2000) |
| collateral inheritance | The appearance of characters in collateral members of a family group, as when an uncle and a niece show the same character inherited from a common ancestor; in recessive characters it may appear irregularly, in contrast to dominant characters transmitted directly from one generation to the next. (05 Mar 2000) |
| collateral ligaments | A number of ligaments on either side of, and serving as a radius of movement of, a joint having a hingelike movement. They occur at the elbow, knee, wrist, metacarpo- and metatarsophalangeal, proximal interphalangeal, and distal interphalangeal joints of the hands and feet. (12 Dec 1998) |
| collateral sulcus | A long, deep sagittal fissure on the undersurface of the temporal lobe, marking the border between the fusiform gyrus laterally and the hippocampal and lingual gyri medially; the great depth of the collateral sulcus results in a bulging of the floor of the occipital and temporal horn of the lateral ventricle, the collateral eminence. Synonym: sulcus collateralis, sulcus occipitotemporalis, collateral fissure, fissura collateralis, occipitotemporal sulcus. (05 Mar 2000) |
| collateral trigone | A triangular prominence of the floor of the lateral ventricle at the transition between occipital and temporal horn, continuous rostrally with the collateral eminence and, like the latter, caused by the deep penetration of the collateral sulcus from the ventral surface of the temporal lobe. Synonym: trigonum collaterale, trigone of lateral ventricle, trigonum ventriculi, ventricular trigone. (05 Mar 2000) |
| collateral vessel | A branch of an artery running parallel with the parent trunk, a vessel that runs in parallel with another vessel, nerve, or other long structure. Synonym: vas collaterale. (05 Mar 2000) |
| communicating branch of median nerve with ulnar nerve | <anatomy, nerve> Branch of median nerve joining the ulnar nerve in the hand; the anterior interosseous branch of the median nerve may also communicate with the ulnar nerve in the proximal forearm. Synonym: ramus communicans nervi mediani cum nervo ulnari. (05 Mar 2000) |
| posterior branch of recurrent ulnar artery | <anatomy, artery> Contributes to blood supply of flexor carpi ulnaris and to articular network of elbow. Synonym: ramus posterior arteriae recurrentis ulnaris. (05 Mar 2000) |
| superficial branch of the ulnar nerve | <anatomy, nerve> Branch supplying skin of palmar aspect of little and medial half of ring fingers, the portion of the palm proximal to them and the palmaris brevis muscle. Synonym: ramus superficialis nervi ulnaris. (05 Mar 2000) |
| deep branch of the ulnar nerve | <anatomy, nerve> Accompanies deep palmar branch of ulnar artery and deep palmar arch to supply wrist joint, lumbricals 3 & 4, palmar and dorsal interossei adductor pollicis and deep head of flexor pollicis brevis muscles. Synonym: ramus profundus nervi ulnaris. (05 Mar 2000) |
| deep palmar branch of ulnar artery | <anatomy, artery> Branch of the ulnar artery which supplies the hypothenar muscles then passes deep into the palm to the flexor tendons and anastomoses with the deep palmar arch from the radial artery. Synonym: ramus palmaris profundus arteriae ulnaris. (05 Mar 2000) |
| digital collateral artery | <anatomy, artery> Terminal branches of the common palmar digital artery that pass to the side of each finger. Synonym: arteria digitalis palmaris propria, collateral digital artery, digital collateral artery. (05 Mar 2000) |
