Subscapular nerves

The subscapular nerves are innervated by the posterior division of the brachial plexus. These nerves are part of a group of nerves that innervate the muscles that move the scapula.[1] The upper subscapular nerve inserts directly into the upper portion of the subscapularis muscle, thus innervating it. The lower subscapular nerve contains two branches. One branch inserts into the lower portion of the subscapularis muscle and the other branch inserts into the teres major.[2]

Anatomical terminology

Subscapular nerves can refer to:

• Upper subscapular nerve

• Thoracodorsal nerve

The middle subscapular nerve, known as the thoracodorsal nerve also branches from the posterior division of the brachial plexus. This nerve innervates the latissimus dorsi muscle.[3]
