Question

Which one is not a vestigial organ in man?

• A. Vermiform appendix
• B. Plica semilunaris
• C. Ear muscles
• D. Epiglottis

Answer 1

The correct option is D Epiglottis

Vestigial means the remains. Vestigial organs are those which were once in use by our ancestors but now cannot be used because they are remains of once-functional organs. The epiglottis is a fully functional structure and functions to stop the entry of food into our windpipe when we swallow our food. It is not considered as a vestigial organ.

Thus, the correct answer is option D.
