La inervación motora del compartimento anterior del brazo esta dada por que nervio?Pregunta 3Seleccione una:a.Radialb.Medianoc.Cubitald.MusculocutáneoCorrecta

Break Down the Problem

1. Identify the nerves associated with the anterior compartment of the arm.
2. Determine which nerve is primarily responsible for motor innervation in this compartment.

Relevant Concepts

The anterior compartment of the arm is mainly responsible for flexion. The main nerves involved in the innervation of the muscles in this area include:

• Musculocutaneous nerve
• Radial nerve
• Median nerve
• Ulnar nerve

Analysis and Detail

1. Musculocutaneous Nerve: This nerve primarily innervates the biceps brachii, brachialis, and coracobrachialis muscles, which are responsible for flexing the elbow and shoulder.

2. Radial Nerve: This nerve innervates the posterior compartment (extensor muscles) and does not primarily serve the anterior compartment.

3. Median Nerve: While this nerve innervates some muscles in the forearm and hand, it is not the primary motor nerve for the anterior compartment of the arm.

4. Ulnar Nerve: This nerve primarily innervates muscles in the forearm and hand but is not involved in the anterior compartment of the arm.

Verify and Summarize

In summary, out of the options provided, the musculocutaneous nerve is the primary motor nerve for the anterior compartment of the arm. It is responsible for innervating the flexor muscles within this compartment.

Final Answer

The correct answer is d. Musculocutáneo.
