507. A fracture of the hamulus affects the action of which of the following muscles?

A. Superior constrictor of the pharynx
B. Levator veli palatini
C. Tensor veli palatini
D. Salpingopharyngeus
E. Buccinator

The correct answer is choice C. The tendon of tensor veli palatini hooks around the pterygoid hamulus to insert into the palatal aponeurosis. Choice A is incorrect. The superior constrictor inserts into the pharyngeal tubercle of the occipital bone and the midline pharyngeal raphe. Choice B is incorrect. The levator veli palatini (levator palati) arises from the cartilaginous rim of the auditory tube and inserts directly into the palatal aponeurosis. It does not have contact with the hamulus. Choice D is incorrect. Salpingopharyngeus passes from the toms tubarius to the wall of the pharynx. Choice E is incorrect. Buccinator originates from the pterygomandibular raphe and inserts by blending with other muscles of facial expression around the corner of the mouth in an arrangement known as the modiolus.
