Question

In chordates, which of the following helps in locomotion?

• A. Jointed chitinous appendages attached to muscles
• B. Muscles attached to an exoskeleton
• C. Paired muscles attached to an endoskeleton
• D. All of the above
• E. None of the above

Answer 1

The correct option is C Paired muscles attached to an endoskeleton

Paired muscles attached to an endoskeleton helps in locomotion in chordates. They are capable of locomotion by means of muscular movements. Eg. the biceps and triceps bring about the movement of the upper arm.

Thus, the correct answer is option C.
