What is the difference between biceps and triceps in terms of their function and anatomy?

The biceps and triceps are both muscles in the arm, but they have different functions and structures. The biceps are located on the front of the upper arm and are responsible for bending the arm at the elbow. The triceps are located on the back of the upper arm and are responsible for straightening the arm at the elbow. Additionally, the biceps have two heads (long head and short head) while the triceps have three heads (long head, lateral head, and medial head).
