Dissection of Suprascapular and Subscapular Nerve and Axillary Nerve of Qinghai Plateau Yak

The origins, branches and distribution of Suprascapular and subscapular nerve and axillary nerve of the Qinghai Yak were studied with gross anatomical method. The features are as following:The fibers of suprascapular and subcapular nerve are mainly derived from the sixth and seventh cervical (C 6,C 7) nerve roots. These fibers supplying is basically similar to that of ox, water buffalo, horse. The fibers of axillary nerve are mainly derived from the roots of the seventh and the eighth cervical(C 7 and C 8) and the first thoracic (T 1)nerve. These fibers supply the deltoideus, teres minor, infraspinatus, the cleidobrachial part of brachiocephalic muscles and fascia antebrachii and the skin.
