1.1.15 Review of blood vessels and nerves of the shoulder region



We've looked at some prettycomplex and detailed anatomy in the last few minutes. Let's review what we've seen of the veins, arteries and nerves of the shoulder region.

First, the few veins that we saw, the cephalic, subclavian, and brachiocephalic veins.

Next the arteries: the brachiocephalic trunk, the subclavian artery, the axillary artery, the brachial artery; the transverse cervical, and suprascapular arteries. The thoracoacromial, lateral thoracic, subscapular, and anterior, and posterior circumflex humeral arteries.

Lastly nerves, starting with the main components of the brachial plexus. The roots of the brachial plexus, C5, C6, C7, C8 and T1. The three trunks, upper, middle and lower. Each trunk splitting into divisions, an anterior, and a posterior. From the three divisions, three cords arising, the lateral and medial from the anterior divisions, and the posterior from the posterior divisions.

Arising from the lateral cord and the medial cord, the musculocutaneous, median and ulnar nerves, and the pectoral nerves, the medial, and the lateral.

Arising from the posterior cord, the axillary and radial nerves, also the subscapular, and thoracodorsal nerve. Arising higher up, the suprascapular, the long thoracic, and the spinal accessory nerve.
