The medial cutaneous nerve of the forearm, also known as the medial antebrachial cutaneous nerve, is a branch of the medial cord of the brachial plexus and supplies the anterior and medial aspects of the forearm as far distal as the wrist.
Where is the lateral antebrachial cutaneous nerve located?
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 is the function of the cutaneous nerve?
In human anatomy, cutaneous nerves are primarily responsible for providing sensory innervation to the skin.
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.What does the Antebrachial region do?
The main function of the median antebrachial vein is to drain venous blood from the antecubital region of the forearm, a shallow depression distal to the cubital fossa and the superficial structures of the anterior forearm.
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 medial antebrachial cutaneous nerve innervate?
[1] Specifically, the medial antebrachial cutaneous nerve provides sensory innervation of the medial forearm as well as the skin overlying the olecranon. [2] It emerges from the medial cord of the brachial plexus and has sensory cell bodies located in C8 and T1.
What is Wartenberg syndrome?
Introduction. Wartenberg’s Syndrome is described as the entrapment of the superficial branch of the radial nerve with only sensory manifestations and no motor deficits. In this condition, the patient reports pain over the distal radial forearm associated with paresthesia over the dorsal radial hand.What does Antebrachial mean?
relating to the forearm: the antebrachial vein.
How do you fix a lateral femoral cutaneous nerve?In more severe cases, corticosteroid injections or injectable pain medications may relieve symptoms. Rarely, surgery is necessary to correct any compression on the lateral femoral cutaneous nerve. Surgery is usually only recommended for people who try other treatments but still experience symptoms.

What are the signs and symptoms of lateral femoral cutaneous nerve entrapment?
Symptoms of lateral femoral cutaneous nerve entrapment may include anterior and lateral thigh burning, tingling, and numbness, which increase with standing, walking, or hip extension (and sometimes also with lying prone). Symptoms usually are unilateral but may be bilateral in rare cases.
What happens if you damage a cutaneous nerve?
Effects of Injury Injury to the nerve may result in meralgia paresthetica. Meralgia paresthetica is an altered sensation of the lateral cutaneous nerve of the thigh that manifests clinically as numbness, burning, itching, or pain over the anterior and lateral aspects of the thigh.
Where do cutaneous nerves come from?
Cutaneous innervation of the shoulder and upper limb comes from multiple peripheral nerves originating from cervical and thoracic nerve roots, with most of the nerves originating from the brachial plexus.
What is cutaneous nerve damage?
Meralgia paresthetica is a condition characterized by tingling, numbness and burning pain in the outer part of your thigh. The condition is caused by compression of the lateral femoral cutaneous nerve, which supplies sensation to your upper leg.

What part of the body is the Antebrachial region?
the antebrachial region encompassing the forearm, the carpal region encompassing the wrist, the palmar region encompassing the palm, the digital/phalangeal region encompassing the fingers.
Is the Antebrachial region part of the upper extremity?
the area of the upper limb between elbow and hand.
What does the medial cutaneous nerve of arm supply?
The medial cutaneous nerve of the arm, also known as the lesser internal cutaneous nerve of arm, is a branch of the medial cord of the brachial plexus and supplies the skin of the medial side of the arm as far distal as the medial epicondyle.
What does the axillary nerve innervate?
The axillary nerve supplies three muscles in the arm: deltoid (a muscle of the shoulder), triceps (long head) and teres minor (one of the rotator cuff muscles).
What is innervated by ulnar nerve?
The ulnar nerve innervates the flexor muscles of the forearm including the flexor carpi ulnaris and flexor digitorum profundus. It also innervates the intrinsic muscles of the hand including the palmaris brevis, lumbricals, hypothenar and interossei muscles.
Where is posterior cutaneous nerve of forearm from?
It arises from the radial nerve in the posterior compartment of the arm, often along with the posterior cutaneous nerve of the arm.
What is anterior interosseous nerve?
Anterior Interosseous Nerve (AIN) is a motor branch from the Median nerve and runs deep in the forearm along with the anterior interosseous artery. It innervates three muscles in the forearm; an isolated palsy of these muscles is known as AIN Syndrome.
Where does Brachioradialis attach?

Where is the antecubital region located?
The Cubital Fossa is a triangular-shaped depression, located between the forearm and the arm on the anterior surface of the elbow, with the apex of the triangle pointing distally. It is also known as the “antecubital” because it lies anteriorly to the elbow.
What is Antebrachial vein?
The median antebrachial vein is a superficial vein of the anterior forearm that drains the superficial structures of the forearm and wrist between the basilic and cephalic veins.
Does Antebrachial mean forearm?
The forearm, i.e. the part of the arm between the elbow and the wrist. The term is used in anatomy to identify it from the brachium (or the upper arm). Word origin: from Latin, prefixal form of prep.
How do you fix Wartenberg syndrome?
- Removal of tight wrist wear.
- Activity modification.
- Splint.
- Painkillers.
How do you sleep with radial nerve entrapment?
When sleeping on your side, place a pillow in front of you to support the whole arm, limit elbow flexion, and keep the wrist and fingers flat, in a neutral position. Consider sleeping on your back with your arms at your sides or on pillows to keep your elbows and wrists in an ideal position.
Is radial nerve palsy permanent?
Many patients with radial nerve palsy will see complete recovery or symptom relief after treatment. In some cases, complications may occur, including: Partial or complete loss of feeling in the hand: If the radial nerve doesn’t heal completely, numbness may be permanent.
Does walking help meralgia paresthetica?
Exercising for 30 minutes a day at least three or four times a week should help ease meralgia paresthetica pain. Some exercises to try include: brisk walking.
