What happens if the musculocutaneous nerve is damaged?
Damage to this nerve can result in problems with the tissues in innervates, including: Loss of sensation in the skin on the front side of the forearm. Weakened flexion at the shoulder and elbow. Weakened rotation of the arm.
What nerve supplies the skin of the lateral forearm?
Abstract. The musculocutaneous nerve supplies three upper arm muscles that produce flexion of the arm at the elbow (biceps, brachialis, and coracobrachialis) and a sensory branch that supplies the skin of the lateral side of the anterior forearm.
What does the lateral cutaneous nerve of the forearm innervate?
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 nerve runs down the outside of your arm?
Radial nerve. This nerve passes down the back and outside of the upper arm. The radial nerve supplies muscles that straighten the elbow, and lift and straighten the wrist, thumb, and fingers.
Where is the lateral antebrachial cutaneous nerve?
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.
What is the lateral side of the forearm?
Radius
Ulna and Radius The ulna is located on the medial side of the forearm, and the radius is on the lateral side.
Where is the lateral femoral cutaneous nerve located?
The nerve passes under the lateral aspect of the inguinal ligament, in a compartment sometimes called the muscular lacuna, approximately 10-15 mm medial to the ASIS to lie on the anterior surface of the sartorius muscle and deep to the fascia lata.
What nerves are in your forearm?
Several major nerves continue from the arm into the forearm, including the radial, median, and ulnar nerves. These nerves control the forearm muscles that move the hands and fingers through tendons that pass through the wrist.
What is a radial nerve injury?
A radial nerve injury refers to damage to the nerve in the upper arm. This nerve controls the triceps muscle. It also helps extend the wrist and fingers and provides sensation in part of the hand. The radial nerve is close to the bone in the upper arm, so it is vulnerable to injury, especially if the arm breaks.
What is lateral femoral cutaneous block?
Lateral femoral cutaneous nerve blocks are a minimally invasive, non-surgical treatment for chronic pain. These nerve blocks can help in the diagnosis of chronic hip/thigh pain. In addition, this pain management technique can also provide therapeutic relief by reducing pain signals originating from these nerves.
What is an external cutaneous nerve?
The Lateral Femoral Cutaneous Nerve (n. cutaneus femoralis lateralis; external cutaneous nerve) arises from the dorsal divisions of the second and third lumbar nerves. It emerges from the lateral border of the Psoas major about its middle, and crosses the Iliacus obliquely, toward the anterior superior iliac spine.
What is a lateral nerve?
Lateral nerve is a general term describing nerves located at the lateral parts of the body. The term lateral means pertaining to the side, for instance the side of the knee facing away from the body is lateral, while the side facing the other knee is medial.
