This section passes through the articulation of the first rib with the manubrium of the sternum (6, 93), inferior thyroid veins (2), right brachiocephalic artery (97) and vein (94), left common carotid artery (91), and left subclavian artery (89). The most common branching pattern of the aortic arch is seen in this specimen. In 70% of individuals the branching order is right brachiocephalic trunk (97), left common carotid artery (91), and left subclavian artery (89).
Several bronchopulmonary segments are identified: left lung, upper lobe and division, anterior (86) and apical posterior (62) segments, and right lung, upper lobe, posterior (34), apical (14), and anterior (7) segments.
The brachial plexus of nerves to the arm, forearm, and hand is breaking up into its terminal branches, which include musculocutaneous (79), median (72), radial (68), and ulnar (67) nerves. A branch of the radial, the axillary nerve (70), is also seen.
