Radial nerve It innervates the medial and lateralheads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.ith the lateral and medial heads of the triceps innervated, the radial nerve emerges from the radial groove on the lateral aspect of the humerus. At this point, it pierces the lateral intermuscular septum and enters the anterior compartment of the arm.

Median nerve Median nerve. In the upper arm and near the shoulder, the median nerve branches off of the brachial plexus. It initially spans the length of the upper arm, as it runs a course parallel to the brachial artery. A portion of its path covers the medial side of the arm, near both the biceps brachii and brachialis muscle.

Brachial Plexus Anatomy The axillary nerve is derived from the posterior cord. The axillary nerve leaves the brachial plexus at the lower border of the subscapularis muscle and continues along the inferior and posterior surface of the axillary artery as the radial nerve.The axillary nerve serves as motor innervation to the deltoid and teres minor muscles, as seen in the image below.he ventral rami of C5 and C6 unite to form the upper trunk. The suprascapular nerve and the nerve to the subclavius arise from the upper trunk. The suprascapular nerve contributes sensory fibers to the shoulder joint and provides motor innervation to the supraspinatus and infraspinatus muscles.

Nerves of the Arm and Hand Several major nerves continue from the arm into the forearm, including the radial, median, and ulnar nerves. These nerves control the forearm muscles that move the hands and fingers through tendons that pass through the wrist. Skin in the posterior forearm and extensor muscles of the hand and fingers are supplied by the branches of the radial nerve.

Posterior interosseous nerve Posterior interosseous nerve. The posterior interosseous nerve (or dorsal interosseous nerve) is a nerve in the forearm. It is the continuation of the deep branch of the radial nerve, after this has crossed the supinator muscle. It is considerably diminished in size compared to the deep branch of the radial nerve. The nerve fibers originate from cervical segments C7 and C8.

The Radial Nerve The radial nerve then descends down the arm, travelling in a shallow depression on the surface of the humerus. This depression is known as the radial groove. As it moves inferiorly, the radial nerve wraps around the humerus in a lateral direction, and gives a branch to the lateral head of the triceps brachii.During its course in the arm, the nerve is accompanied by the deep branch of the brachial artery.o enter the forearm, the radial nerve moves anteriorly over the lateral epicondyle of the humerus, through the cubital fossa. Within the forearm, the nerve terminates by dividing into two branches: 1  Deep branch – A motor branch.

Nerves of the Arm and Hand 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.

Brachial Plexus Injury (BPI) The brachial plexus is a network of nerves that originate in the neck region and branch off to form most of the other nerves that control movement and sensation in the upper limbs, including the shoulder, arm, forearm, and hand. The radial, median, and ulnar nerves originate in the brachial plexus.

- Also running along the posterior of the arm, the radial nerve provides nerve signals to the triceps brachii muscle that extends the forearm and the skin of the posterior arm. The musculocutaneous nerve innervates the flexor muscles of the arm, including the biceps brachii and brachialis muscles.he nerves of the arm and hand perform a substantial two-fold role: commanding the intricate movements of the arms all the way down to the dexterous fingers, while also receiving the vast sensory information supplied by the sensory nerves of the hands and fingers.

Lateral Antebrachial Cutaneous Nerve (LABC) • Patient complaints of pain at the dorso-radial/lateral forearm/wrist area require examination of this nerve especially after previous surgery/injury to his area. • Provides sensation to the lateral cutaneous aspect of the forearm.• Originates from roots C5, C6, C7 and branches from the musculocutaneous nerve.ourse: The musculocutaneous nerve becomes the lateral antebrachial cutaneous nerve when the brachialis nerve branch forks off to innervate the brachialis muscle. The lateral antebrachial cutaneous nerve continues distally to innervate the lateral aspect of the forearm.
