Question

Which one of the following is antagonistic pair of biceps?

• A. Quadrieps femoris
• B. Quadratus femoris
• C. Triceps
• D. Branchialis

Answer 1

Answer: (C)

Muscles cannot expand. They can only contract. Hence, muscles responsible for body movements frequently occur in pairs called agonist-antagonist pairs, for example, biceps and triceps. The biceps cause movement towards the body or central axis and triceps cause movement away from the body or away from the central axis.

Hence the correct option is C.
