Five major nerves extend from the brachial plexus into the arm: the axillary, musculocutaneous, median, radial, and ulnar nerves. Each of these nerves carries information in the form of nerve impulses to and from a particular region of the arm and hand.

There are 6 topics covered in the nerves of the upper limb, an overview of the brachial plexus and a more in-depth look into it’s 5 main branches: axillary, musculocutaneous, median, radial, and ulnar nerves.

In the upper arm the radial nerve wraps around the back side of the humerus bone. The nerve gives function to the triceps muscles on the back of the arm to straighten the elbow. Because the radial nerve wraps around the humerus bone, it can be stretched or torn when the humerus bone is …

The radial nerve originates in the axillary region, positioned posterior to the axillary artery, and exits the axilla via the triangular interval to enter the posterior compartment of the arm. It then descends, wrapping around the spiral groove of the humerus, before entering the forearm anterior to the lateral epicondyle through the cubital fossa, where it divides into superficial and deep ...
