The medial antebrachial cutaneous nerve, along with the posterior and lateral antebrachial cutaneous nerves, is responsible for providing sensation to the skin of the forearm.[1] Specifically, the medial antebrachial cutaneous nerve provides sensory innervation of the medial forearm as well as the skin overlying the olecranon.[2] The medial antebrachial cutaneous nerve emerges from the medial cord of the brachial plexus and has sensory cell bodies located in the dorsal root ganglia of C8 and T1. The nerve travels distally along the upper arm running through the brachial fascia along with the basilic vein approximately 10 cm proximal to the medial epicondyle. As the medial antebrachial cutaneous nerve exits the brachial fascia, it divides into two major branches, anterior and posterior, which continue distally to the wrist.
