"triceps" の定義と意味

What is "triceps"?

The triceps refers to a muscle group located on the back of the upper arm. It consists of three heads: the long head, lateral head, and medial head. The triceps are responsible for the extension of the elbow joint, straightening the arm, and providing power for pushing movements. They work in coordination with the biceps to facilitate balanced movement and stability in the arm. The triceps play a crucial role in activities such as lifting, pushing, and throwing. Well-developed triceps contribute to arm strength, aesthetics, and overall upper-body functionality.
