Where is the median nerve located in the elbow and forearm?

Forearm. The median nerve continues in the cubital fossa medial to the brachial artery and passes between the two heads of the pronator teres, deep to the bicipital aponeurosis (aponeurosis of biceps) and superficial the brachialis muscle.

What is the median nerve?

The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus.
