The posterior cord is a part of the brachial plexus. It consists of contributions from all of the roots of the brachial plexus.^[1]

The posterior cord gives rise to the following nerves:^[2]

Name	Roots	Supplies
upper subscapular nerve	C5-C6	subscapularis muscle of the rotator cuff
lower subscapular nerve	C5-C6	subscapularis muscle, teres major muscle
thoracodorsal nerve	C6-C8	latissimus dorsi muscle
axillary nerve	C5-C6	sensation to the shoulder and motor to the deltoid muscle, the teres minor and the triceps brachii (long head) muscle
radial nerve	C5-C8, T1	triceps brachii muscle, the brachioradialis muscle, the extensor muscles of the fingers and wrist (extensor carpi radialis muscle), supinator, and the extensor and abductor muscles of the thumb

Pattern of nitrergic cells and fibers organization in the central nervous system of the Australian lungfish, Neoceratodus forsteri (Sarcopterygii: Dipnoi).

López JM, Morona R, González A.
The Journal of comparative neurology. 2019 Aug;527(11)1771-1800.
The Australian lungfish Neoceratodus forsteri is the only extant species of the order Ceratodontiformes, which retained most of the primitive features of ancient lobe finned-fishes. Lungfishes are the closest living relatives of land vertebrates and their study is important for deducing the neural t

Posterior cord
	Plan of brachial plexus. (Posterior cord is shaded gray.)
	The right brachial plexus with its short branches, viewed from in front. The Sternomastoid and Trapezius muscles have been completely removed, the Omohyoid and Subclavius have been partially removed; a piece has been sawed out of the clavicle; the Pectoralis muscles have been incised and reflected.
