Posterior cutaneous nerve of arm
Latin  Nervus cutaneus brachii posterior

The posterior cutaneous nerve of arm (internal cutaneous branch of musculospiral, posterior brachial cutaneous nerve) is a branch of the radial nerve that provides sensory innervation for much of the skin on the back of the arm. It arises in the axilla.

It is of small size, and passes through the axilla to the medial side of the area supplying the skin on its dorsal surface nearly as far as the olecranon.

In its course it crosses behind and communicates with the intercostobrachial.
