It should not be hard to figure out that the musculocutaneous nerve (MC) contains fibers that are motor to the muscle and sensory from the skin (cutaneous). We will find the nerve coursing along the medial aspect of the biceps brachii muscle (A).

Along with this muscle, what other muscles are innervated by the musculocutaneous nerve?

The biceps brachii and brachialis muscles are innervated by the musculocutaneous nerve and act to flex the elbow. The coracobrachialis muscle is also innervated by this nerve, although it's action is upon the shoulder.

Sensory innervation from what aspect of the forearm is found in the musculocutaneous nerve?

Sensory innervation from the medial aspect of the forearm is found in the musculocutaneous nerve. (raMu laMp)
