| posterior cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the posterior divisions of the upper, middle and lower trunks which lies posterior to the axillary artery; it gives rise to the upper and lower subscapular and thoracodorsal nerves, terminates by dividing into the axillary, and radial nerves. Synonym: fasciculus posterior plexus brachialis. (05 Mar 2000) |
|---|---|
| superficial brachial artery | <anatomy, artery> An occasional variation in which the brachial artery lies superficial to the median nerve in the arm. Synonym: arteria brachialis superficialis. (05 Mar 2000) |
| superior lateral brachial cutaneous nerve | <anatomy, nerve> The terminal branch of the axillary nerve supplying the skin over the lower portion of the deltoid and for a distance below its insertion. Synonym: nervus cutaneus brachii lateralis superior, upper lateral cutaneous nerve of arm. (05 Mar 2000) |
| superior trunk of brachial plexus | The nerve bundle formed by the union of the ventral rami of the fifth and sixth cervical nerves and some fibres from the fourth; it contributes fibres to the posterior and lateral cords (fasciculi) of the brachial plexus. Synonym: truncus superior plexus brachialis. (05 Mar 2000) |
| deep brachial artery | <anatomy, artery> Origin, brachial; distribution, humerus and muscles and integument of arm; anastomoses, posterior circumflex humeral, radial recurrent, recurrent interosseous, ulnar collateral, i.e., articular vascular network of elbow. Synonym: arteria profunda brachii, deep brachial artery. (05 Mar 2000) |
| supraclavicular part of brachial plexus | The part of the brachial plexus, including the roots, trunks, and divisions, that gives rise to the dorsal scapular, long thoracic, suprascapular and subclavian nerves. Synonym: pars supraclavicularis plexus brachialis. (05 Mar 2000) |
| inferior lateral brachial cutaneous nerve | <anatomy, nerve> A branch of the radial nerve supplying the skin of the lower lateral aspect of the arm; it frequently is a branch of the posterior antebrachial nerve. Synonym: nervus cutaneus brachii lateralis inferior, lower lateral cutaneous nerve of arm. (05 Mar 2000) |
| inferior trunk of brachial plexus | The nerve bundle formed by the union of the ventral rami of the eighth cervical and first thoracic nerves; it provides fibres to the posterior and medial cords (fasciculi) of the brachial plexus. Synonym: truncus inferior plexus brachialis. (05 Mar 2000) |
| infraclavicular part of brachial plexus | The part of the brachial plexus that extends from the level of the clavicle downward into the axilla; it includes the cords of the plexus and their branches. Synonym: pars infraclavicularis plexus brachialis. (05 Mar 2000) |
| trunks of brachial plexus | The superior, middle, and inferior trunks; they divide distally to form the cords (fasciculi) of the plexus. Synonym: trunci plexus brachialis. (05 Mar 2000) |
| lateral cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the anterior divisions of the superior and middle trunks which is located lateral to the axillary artery. This cord gives off the lateral pectoral nerve and terminates by dividing into the musculocutaneous nerve and the lateral root of the median nerve. Synonym: fasciculus lateralis plexus brachialis.
