Introduction

This article is about the median nerve. The median nerve is a nerve originating from the brachial plexus of the arm. It is formed by the merging of the medial and lateral chords, which originate from the roots C5 to T1.

Course

The median nerve passes through the cubital fossa between the two heads of the Pronator Teres muscle, then behind the Flexor digitorum superficialis, resting posteriorly on the flexor digitorum profundus. It then enters the palm behind the flexor retinaculum.

Branches

The median nerve divides into:

• Muscular branches
• Articular branches
• Anterior interosseous nerve
• Palmar cutaneous branch

It is important to note, that the median nerve mainly supplies the muscles of the anterior compartment of the forearm as earlier when talking about it’s course we mentioned a few of those muscles, which are:

• Pronator teres
• Flexor carpi radialis
• Flexor digitorum superficialis
• Palmaris longus

Conclusion

In conclusion, the median nerve is a nerve with roots C5-T1, innervating the anterior compartment of the forearm as well as the palm of the hand
