Which nerve Innervates the lateral side of the forearm?
musculocutaneous nerve
Innervation. The musculocutaneous nerve supplies the coracobrachialis, biceps and brachialis muscles. The lateral cutaneous nerve of the forearm innervates the skin at the anterolateral aspect of the forearm.
What does the lateral antebrachial cutaneous nerve do?
The lateral antebrachial cutaneous nerve provides sensory innervation to the skin on lateral portion of the arm (radial side). Damage to the lateral antebrachial cutaneous nerve will result in a loss of sensation on the skin of the lateral forearm.
What is the lateral nerve of the forearm?
lateral antebrachial cutaneous nerve
The lateral antebrachial cutaneous nerve (LACN) is the terminal sensory branch of the musculocutaneous nerve supplying the lateral aspect of forearm.
What nerve innervates the lateral arm?
It is also called the inferior lateral brachial cutaneous nerve. It is a branch of the radial nerve that provides sensory and vasomotor innervation to the lower, lateral aspect of the arm….

What are the major nerves of the arm and forearm?
Three main nerves run past the elbow and wrist to the hand.
- Median nerve. This nerve passes down the inside of the arm and crosses the front of the elbow.
- Ulnar nerve. This nerve passes down the inside of the arm.
- Radial nerve. This nerve passes down the back and outside of the upper arm.
What nerve supplies the skin of the lateral forearm?
The lateral antebrachial cutaneous nerve (or lateral cutaneous nerve of forearm) (branch of musculocutaneous nerve, also sometimes spelled “antebrachial”) passes behind the cephalic vein, and divides, opposite the elbow-joint, into a volar and a dorsal branch.
Why does my lateral Antebrachial hurt?
Lateral antebrachial cutaneous neuropathy is an uncommon, but easily overlooked, cause of elbow pain in the throwing athlete. Compression of the lateral antebrachial cutaneous nerve by the biceps tendon occurs at the nerve’s exit point from the brachial fascia just proximal to the elbow flexion crease.
What does Antebrachial mean?
relating to the forearm: the antebrachial vein.
Where is the lateral cutaneous nerve of forearm?
Anatomical terms of neuroanatomy The lateral antebrachial cutaneous nerve (or lateral cutaneous nerve of forearm) (branch of musculocutaneous nerve, also sometimes spelled “antebrachial”) passes behind the cephalic vein, and divides, opposite the elbow-joint, into a volar and a dorsal branch.
What does the axillary nerve innervate?
Usually, the axillary nerve contains fibers from the C5 and C6 ventral rami. This nerve innervates the teres minor and deltoid muscles, the skin over the shoulder (upper lateral brachial nerve), and the glenohumeral joint.
What nerves innervate the arms and hands?
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.
What are the three main nerves in your arm?
