The palmar branch of the median nerve arises at the lower part of the forearm.

It pierces the volar carpal ligament, and divides into a lateral and a medial branch;

• The lateral branch supplies the skin over the ball of the thumb, and communicates with the volar branch of the lateral antibrachial cutaneous nerve.
• The medial branch supplies the skin of the palm and communicates with the palmar cutaneous branch of the ulnar.
