Cubital tunnel

Cubital tunnel

Back of right upper extremity, showing surface markings for bones and nerves.

The cubital tunnel is a channel which allows the Ulnar nerve (commonly known as the "funny bone") to travel over the elbow.

Chronic compression of this nerve is known as Cubital Tunnel Syndrome^[1]^[2], a form of Repetitive Strain Injury akin to Carpal Tunnel Syndrome.
