What does the musculocutaneous nerve supply?

What does the musculocutaneous nerve supply?

The musculocutaneous nerve innervates the three muscles of the anterior compartment of the arm: the coracobrachialis, biceps brachii, and brachialis. It is also responsible for cutaneous innervation of the lateral forearm.

What happens when 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 are the two types of nerve conduction?

There are three types of NCS, motor, sensory, and mixed (Fig. 1). Because of differing technical aspects in their performance, these must be performed sequentially, rather than simultaneously, whenever the same mixed nerve is being assessed (ie, motor and sensory NCS cannot be done on a nerve trunk at the same time).

What does the musculocutaneous nerve pass through?

The Musculocutaneous nerve is a terminal branch of the lateral cord of the Brachial Plexus. It emerges at the inferior border of Pectoralis minor muscle.It passes lateral to the axillary and upper part of brachial artery.

How do you test for musculocutaneous nerve damage?

Investigations. Nerve conduction studies, electromyography and MRI scan should confirm a lower motor neurone and sensory nerve lesion and are useful in differentiating musculocutaneous nerve lesions from cervical spine nerve root impingement.

How do you treat a musculocutaneous nerve injury?

Surgical decompression is indicated as first-line treatment if there is paraesthesia, as this suggests that the affected nerve still has some function. Traumatic lesions of the musculocutaneous nerve may be amenable to end-to-end repair. In cases where this is not possible, nerve grafting was the preferred option.

How painful is a nerve conduction study?

As the nerve is stimulated, you will experience a brief electrical shock. This may feel uncomfortable, but it usually isn’t painful. The entire procedure usually takes about 20-30 minutes to complete. In some cases, nerves may be tested in multiple locations, which can make the procedure take slightly longer.

What nerve goes through your bicep?

The musculocutaneous nerve innervates the muscles in the anterior compartment of the arm: Biceps brachii.

What body part has the most nerves?

The clitoris has 8,000 nerve endings (and nine other things we learned from a new artwork)

  • A clitoris is like an iceberg.
  • There are more than 8,000 nerve endings in the tip of the clitoris alone.
  • They can swell as much as 300 per cent when engorged.
  • G-spot and penetrative orgasms are clitoral.
