| ulnar nerve | <anatomy, nerve> A major nerve of the upper extremity. In humans, the fibres of the ulnar nerve originate in the lower cervical and upper thoracic spinal cord (usually c7 to t1), travel via the medial cord of the brachial plexus, and supply sensory and motor innervation to parts of the hand and forearm. (12 Dec 1998) |
|---|---|
| ulnar nerve compression syndrome | <syndrome> A condition caused by compression or entrapment of the ulnar nerve. It may involve both sensory and motor problems and most often results from compression or entrapment of the ulnar nerve at the elbow (cubital tunnel syndrome). Compression of the nerve may occur during normal activities or as a complication of general anaesthesia. (12 Dec 1998) |
| 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) |
|---|---|
| palmar branch of ulnar nerve | <anatomy, nerve> Branch of ulnar nerve arising in distal forearm and accompanying palmar artery into hand where it supplies skin of little finger and medial half of ring finger and adjacent parts of palm. Synonym: ramus palmaris nervi ulnaris. (05 Mar 2000) |
| groove for ulnar nerve | <anatomy, nerve> A furrow on the posterior surface of the medial epicondyle of the humerus, lodging the ulnar nerve. Synonym: sulcus 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) |
| dorsal branch of the ulnar nerve | <anatomy, nerve> Branch arising from the ulnar nerve proximal to the wrist for distribution to the medial side of the dorsum of the hand and proximal portion of the little finger and medial side of ring finger. Synonym: rami dorsales nervi ulnaris. (05 Mar 2000) |
| ulnar branch of medial antebrachial cutaneous nerve | <anatomy, nerve> Branch of the medial antebrachial cutaneous nerve supplying the skin of the medial portion of the proximal two-thirds of the dorsal side of the forearm. Synonym: ramus ulnaris nervi cutanei antebrachii medialis. (05 Mar 2000) |
| ulnar communicating branch of superficial radial nerve | <anatomy, nerve> Ulnar communicating branch of superficial branch of radial nerve, joining the dorsal branch of the ulnar nerve in the hand conveying sensation from the dorsal aspect of adjacent sides of the middle and ring fingers. Synonym: ramus communicans ulnaris nervi radialis. (05 Mar 2000) |
| palmar carpal branch of ulnar artery | <anatomy, artery> A branch of the ulnar artery that supplies the carpal joints and communicates with the anterior carpal branch of the radial artery. Synonym: ramus carpalis palmaris arteriae ulnaris, ramus carpeus palmaris arteriae ulnaris. (05 Mar 2000) |
| recurrent ulnar artery | <anatomy, artery> Origin, ulnar artery; distribution, two branches, anterior and posterior, pass medially in front of and behind the elbow joint; anastomoses, superior and inferior ulnar collateral, i.e., with articular vascular network of elbow. Synonym: arteria recurrens ulnaris. (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) |
| superior ulnar collateral artery | <anatomy, artery> Origin, brachial; distribution, elbow joint; anastomoses, posterior ulnar recurrent and inferior ulnar collateral, as part of the articular vascular network of the elbow. Synonym: arteria collateralis ulnaris superior. (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) |
| dorsal carpal branch of ulnar artery | <anatomy, artery> A branch of the ulnar artery that passes to the dorsal side of the carpus to enter the dorsal carpal network. Synonym: ramus carpeus dorsalis arteriae ulnaris, ramus carpalis dorsalis arteriae ulnaris. (05 Mar 2000) |
| inferior ulnar collateral artery | <anatomy, artery> Origin, brachial; distribution, arm muscles at back of elbow; anastomoses, anterior and posterior ulnar recurrent, superior ulnar collateral, profunda brachii, and recurrent interosseous, as part of the articular network of the elbow. Synonym: arteria collateralis ulnaris inferior, arteria anastomotica magna, great anastomotic artery. (05 Mar 2000) |
