Pronation of the forearm and the flexion of the elbow
The function of the musculotaneous nerve is to supply motor fibers to the biceps brachii and brachialis muscles as well as providing cutaneous sensation of the lateral forearm.

The musculocutaneous nerve innervates the muscles in the anterior compartment of the arm, including the biceps brachii and brachialis. It also provides sensory innervation to the skin on the lateral surface of the forearm.

The biceps include both skeletal muscle tissue and connective tissue. The skeletal muscle tissue is responsible for the movement of the biceps, while the connective tissue helps to support and stabilize the muscle fibers.
it contracts
pennate is the opposite of parallel (fusiform) parallel muscle eg biceps brachii has fibres which run parallel, whereas pennate fibres run diagonally to the axis of movement, unipennate, bipennate and multipennate refers to the number of tendonous attachments unipennate muscle fibers which converge on one side of a tendon ca be found in the gluteus maximus, bipennate fibers converge in a featherlike way towards a central tendon, and multipennate converge on more tendons such as deltoid which has three heads.
When you bend your arm at the elbow and feel your biceps your upper arm muscle contracts.👏👏
A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.

No, intrafusal fibers don't contract.
Your biceps feel tight after a workout because the muscles have been worked hard and may have small tears in the muscle fibers. This can lead to inflammation and a feeling of tightness as the muscles repair and grow stronger.
