"biceps" 的定义和意义

What is "biceps"?

The biceps is a skeletal muscle located in the upper arm. It is a prominent muscle that consists of two heads, the short head, and the long head, which converge to form a tendon that attaches to the radius bone of the forearm. The biceps muscle is responsible for flexing the elbow joint, allowing for movements like bending the arm and bringing the hand closer to the shoulder. Additionally, it contributes to the supination of the forearm, rotating the palm upward. The biceps muscle is highly visible and commonly associated with strength and physical fitness. It is actively engaged during activities that involve lifting, pulling, and gripping.
