Masseter:
a. originates on the zygomatic arch and the maxilla
b. inserts on the angle and ramus of the mandible
c. is innervated by the trigeminal (v) nerve
d. all of the above statements are true

The correct option is : d. all of the above statements are true

Explanation:

The masseter is a quadrilateral-shaped thick muscle, found only in the mammals. It is one of the muscles of mastication and is particularly very strong in the herbivores, as it used to facilitate chewing plant matter.

This muscle is composed of- superficial head and deep head.

The masseter muscle arises on the zygomatic arch and on the maxillary process of the zygomatic bone.

Whereas, the muscle inserts on the angle and ramus of the mandible.

The anterior division of mandibular division (V3) of the trigeminal nerve innervates the masseter muscle.

Therefore, all of the statements given are true.
