What are the branches of musculocutaneous nerve?

Branches

  • Corocobrachialis.
  • Brachialis ( also has supply from Radial nerve)
  • Biceps Brachii(both long head and short head)

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 does musculocutaneous nerve turn into?

The musculocutaneous nerve terminates as the lateral cutaneous nerve of the forearm that supplies the anterolateral skin of the forearm.

Which movement will be affected in paralysis of musculocutaneous nerve?

Isolated injury to the musculocutaneous nerve is a rare occurrence. Associated signs and symptoms of an isolated musculocutaneous neuropathy may include weakness in elbow flexion or shoulder flexion, atrophy of the biceps brachii, and pain or paresthesia at the lateral forearm.

Which nerve stimulates the quadriceps femoris iliacus and sartorius muscles?

The femoral nerve arises from the nerve roots of L2, L3, and L4. It forms within the belly of the psoas muscle and then exits on its lateral aspect to innervate the quadriceps femoris, iliacus, pectineus, and sartorius muscles and the skin of the anterior thigh and medial aspect of the leg.

Is musculocutaneous nerve sensory or motor?

The musculocutaneous nerve is a mixed motor and sensory nerve. It arises from the lateral cord of the brachial plexus and receives contributions from C5–C7 cervical roots.

What causes musculocutaneous nerve damage?

Injuries to the musculocutaneous nerve are associated with weakness of arm flexion and sensory loss along the lateral forearm. In children, musculocutaneous neuropathies are rare and generally caused by compressive or overuse injuries, or are associated with HNPP.

What nerves control your legs?

The sciatic nerve supplies major parts of the skin and muscles in the thigh, leg, and foot. This mixed innervation is responsible for vital motor and sensory functions throughout each leg.

What nerve innervates the hamstrings?

the sciatic nerve
The hamstring muscle complex is innervated by nerves that arise from the lumbar and sacral plexuses. These plexuses give rise to the sciatic nerve (L4-S3), which bifurcates into the tibial and common peroneal (fibular) nerves at the level of the tibiofemoral joint.
