Nov 13, 2015 · An in-depth guide to the nerve supply to the upper limb, including tips on identifying peripheral nerve injuries in OSCEs, videos and a handy summary table.

Another nerve of the upper limb is the musculocutaneous nerve, it contains nerve fibres from roots C5 to C7 and supplies the muscles of the anterior compartment of the upper arm. It also has a sensory branch which supplies the lateral aspect of the forearm.

Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.

In the forearm, the median nerve supplies almost all the flexor muscles and all the pronator muscles of the forearm with nerves. Its function allows the wrist and fingers to bend. It also pronates the forearm (rotating the hand to face palm down).

Feb 8, 2021 · The nerve supplies all the muscles at the back of the forearm (extensor group) except brachioradialis, extensor carpi radialis longus, and anconeus which are supplied by the radial nerve itself. Nerve injuries

Jul 24, 2023 · The nerves in the forearm derive from branches of the brachial plexus and the medial antebrachial cutaneous nerve. The five branches of the brachial plexus are the musculocutaneous, axillary, median, ulnar, and radial nerves.[3]

Nerve supply: Anterior interosseous nerve; Action: Flexes the distal phalanx of the thumb; Pronator quadratus: Origin: The oblique ridge on the lower one-fourth of the anterior surface of the shaft of ulna; Insertion: Lower one-fourth of the anterior surface and the anterior border of the radius, Ulnar notch; Nerve supply: Anterior interosseous ...

Nov 3, 2023 · All together these form the neurovascular compartment of the upper limb. The nerves of the upper limb originate from the brachial plexus and include the musculocutaneous, axillary, median, radial and ulnar nerves. The main artery supplying blood to the upper limb is the subclavian artery.

4 days ago · Along the anterior of the forearm, the median and ulnar nerves supply nerve signals to the skin and to the flexor muscles of the hand and fingers. As major sensory components of the body, the hands are the destination for a majority of the nerves in the upper limb.

The nerve supply for the forearm can be divided into superficial (or cutaneous) and deep innervation. Cutaneous innervation comprises the following nerves: —lateral cutaneous nerve of the forearm (C5, C6), which innervates skin of the lateral side of …
