biceps

Biceps are a muscle in the upper arm that is responsible for bending the arm at the elbow. It is a large, powerful muscle that is often used in activities that require arm strength, such as lifting weights or playing sports.

The biceps is made up of two parts: the short head and the long head. The short head is attached to the shoulder blade, and the long head is attached to the upper arm bone. The two heads of the biceps come together to form a tendon that is attached to the forearm bone.

When the biceps contracts, it pulls on the forearm bone, which bends the arm at the elbow. The biceps is a very important muscle for everyday activities, such as lifting objects and carrying groceries.

In science, the biceps can be used to study muscle anatomy and physiology. For example, scientists might use the biceps to study how muscles work or how they respond to exercise.
