Question

Quizplus · Accepted Answer

The mastoid process is a bony projection on the temporal bone of the skull, and it serves as the point of attachment for several muscles of the neck. It is located posterior to the external auditory meatus, not anterior as stated in choice C. Choice A is incorrect as the mastoid process is on the temporal bone, not the parietal bone. Choice D is partially correct, but the mastoid process is not a projection of the parietal bone. Therefore, the best answer is B.
