Based on their embryonic origin, which set of muscles is most closely related?
A) chewing muscles-tongue muscles
B) extrinsic eye muscles-pharyngeal constrictors
C) suprahyoid muscles-infrahyoid muscles
D) trapezius-erector spinae

Question

Quizplus · Accepted Answer

Both extrinsic eye muscles and pharyngeal constrictors develop from the embryonic branchial arches, specifically the second arch in the case of extrinsic eye muscles and the third and fourth arches in the case of pharyngeal constrictors. This close embryonic origin indicates a close evolutionary relationship between these sets of muscles.
