Which nerve Innervates the lateral side of the forearm?
The musculocutaneous nerve gives rise to the lateral cutaneous nerve of the forearm as it passes lateral to the biceps tendon. This nerve supplies sensation to the radial distribution of the forearm. The radial nerve forms from the C5-T1 nerve roots.
What nerve supplies the lateral cutaneous nerve of the arm?
The superior lateral cutaneous nerve of arm (or superior lateral brachial cutaneous nerve) is the continuation of the posterior cord of the axillary nerve, after it pierces the deep fascia. It contains axons from C5-C6….

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 nerves innervate the forearm muscles?
The three main nerves of the forearm are the median, ulnar, and radial nerves. There are also three nerves that innervate the skin (medial, lateral, and posterior cutaneous nerves). All of these nerves branch from the brachial plexus in the axillary region of the arm and traverse down the upper extremity to the hand.
What are the cutaneous nerves of the forearm?
There are three cutaneous nerves that provide a sensory supply for the skin of the forearm. These three nerves are the medial antebrachial cutaneous nerve, lateral antebrachial cutaneous nerve and the posterior antebrachial cutaneous nerve.
What is the lateral side of the forearm?
The ulna is located on the medial side of the forearm, and the radius is on the lateral side. These bones are attached to each other by an interosseous membrane. The ulna is the medial bone of the forearm. It runs parallel to the radius, which is the lateral bone of the forearm (Figure 2).
What is lateral cutaneous nerve?
The lateral cutaneous nerve of the thigh (also called the lateral femoral cutaneous nerve) is a cutaneous nerve of the thigh. It originates from the dorsal divisions of the second and third lumbar nerves from the lumbar plexus. It passes under the inguinal ligament to reach the thigh.
Which nerve supplies the cutaneous distribution of the skin over both the arm and forearm?
The musculocutaneous nerve, after supplying the coracobrachialis, biceps, and brachialis muscles, continues in the interval between the last two muscles as a sensory nerve to supply the skin over the anterolateral aspect of the forearm, often as far as the thenar eminence.
What nerves affect forearms?
The median nerve provides motor (movement) functions to the forearm, wrist and hand. It also sends touch, pain and temperature sensations from the lower arm and hand to the brain. A pinched median nerve can cause carpal tunnel syndrome.
What is the muscle under your forearm called?
Brachialis. This muscle lies underneath your biceps. It acts as a bridge between your humerus and ulna, one of the main bones of your forearm. It’s involved with the flexing of your forearm.
What is the lateral bone of the lower arm?
The radius is the lateral bone of the forearm. The ulna is the medial bone of the forearm; it articulates with the humerus and radius. The humerus is the largest bone of the upper limb and is the only bone of the (upper) arm.
How do you cure the lateral femoral cutaneous nerve?
- Corticosteroid injections. Injections can reduce inflammation and temporarily relieve pain.
- Tricyclic antidepressants. These medications might relieve your pain.
- Gabapentin (Gralise, Neurontin), phenytoin (Dilantin) or pregabalin (Lyrica).
