Identify an antagonistic pair of muscles in the human bod

An example of an antagonistic pair of muscles in the human body is the biceps and triceps located in the upper arm.

Step 1: Understanding Antagonistic Muscles Antagonistic muscles refer to pairs of muscles that work against each other. When one muscle of the pair contracts (shortens), the other muscle relaxes (lengthens).

Step 2: Identifying the Muscles The biceps and triceps are located in the upper arm. The biceps is on the front part of the upper arm, while the triceps is at the back.

Step 3: Understanding Their Function When you bend your arm, your biceps contract and your triceps relax. This is because the biceps are responsible for flexion (bending) of the arm. Conversely, when you straighten your arm, your triceps contract and your biceps relax. This is because the triceps are responsible for extension (straightening) of the arm.

Therefore, the biceps and triceps are an antagonistic pair because they perform opposite actions.
