Which nerve Innervates the lateral side of the forearm?
Musculocutaneous Nerve This nerve provides motor innervation to the biceps, brachialis, and coracobrachialis. The musculocutaneous nerve gives rise to the lateral cutaneous nerve of the forearm as it passes lateral to the biceps tendon.
Where does the lateral cutaneous nerve of the forearm come from?
The lateral cutaneous nerve of the forearm arises from the musculocutaneous nerve in the distal arm.
What nerve supplies the lateral cutaneous part of the 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 nerve does innervate the skin of the anterolateral region of forearm?
The musculocutaneous nerve
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. A lesion of the musculocutaneous nerve is rare and occurs as the result of an injury in the upper arm.
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 nerve is in the forearm?
The ulnar nerve helps you move your forearm, hand and certain fingers. Your forearm extends from the elbow to the hand. The ulnar nerve also sends sensory information like touch, temperature and pain to the brain. Ulnar nerve entrapment occurs when there’s pressure on the ulnar nerve.
What is lateral cutaneous nerve?
The lateral femoral cutaneous nerve, also known as the lateral cutaneous nerve of the thigh, is a sensory branch of the lumbar plexus arising from the posterior divisions of the anterior rami of L2 and L3 spinal nerves.
Where does the lateral antebrachial cutaneous nerve start?
Lateral antebrachial cutaneous nerve This nerve starts its course by passing alongside the lateral margin of the biceps brachii tendon and deep to the cephalic vein. It then continues to descend down the radial aspect of the forearm as far as the wrist.
What is cutaneous nerve of arm?
The medial brachial cutaneous nerve, also known as medial cutaneous nerve of the arm, provides sensation to the medial cutaneous aspect of the arm. It is the smallest and most medial branch of the brachial plexus, originating from C8 and T1 nerve roots.
What does the lateral cutaneous nerve innervate?
The lateral cutaneous nerve of the thigh (L2–L3) innervates the lateral aspect of the thigh and the posterior cutaneous nerve of the thigh (S1–S3) innervates the posterior region of the thigh.
What is a cutaneous nerve?
A cutaneous nerve is a nerve that provides nerve supply to the skin.
What causes nerve pain in forearm?
The common cause of all these nerve compression syndromes is increased pressure — usually from bone or connective tissue — on a nerve in the wrist, arm, or elbow. In most cases, cubital tunnel syndrome and radial tunnel syndrome can be managed with conservative treatments.
What is lateral femoral cutaneous syndrome?
This chronic neurological disorder involves a single nerve—the lateral cutaneous nerve of the thigh, which is also called the lateral femoral cutaneous nerve (and hence the syndrome lateral femoral cutaneous neuropathy ). The term ” meralgia paraesthetica” combines four Greek roots to mean “thigh pain with anomalous perception”.
What nerve stimulates the lateral rectus muscle of the eye?
– Origin and insertion – Relations – Innervation – Blood supply – Function – Clinical significance – Sources
What is the cutaneous function of trigeminal nerves?
Function. The trigeminal nerve is the largest of the 12 cranial nerves.
What is anterior femoral cutaneous nerve?
Anterior cutaneous nerve entrapment syndrome is a nerve entrapment condition that causes chronic pain of the abdominal wall. It occurs when nerve endings of the lower thoracic intercostal nerves are ‘entrapped’ in abdominal muscles, causing a severe localized nerve pain that is usually experienced at the front of the abdomen. ACNES syndrome is frequently overlooked and unrecognized, although the incidence is estimated to be 1:2000 patients. The relative unfamiliarity with this condition often le
