Here the nerve stimulator can be used in identifying the donor motor nerve to the masseter muscle.
The masseter medialis (a jaw muscle) passes partially through the infraorbital foramen and connects to the bone on the opposite side.
The mandible is moved primary by the four muscles of mastication: the masseter, medial pterygoid, lateral pterygoid and the temporalis.
Both their medial and lateral masseter muscles are displaced forward, making them adept at gnawing.
The masseter muscle does attach directly behind the zygomatic arch in a manner very different from sciuromorphs.
The number of larvae per g in m. masseter was from 2.1 to 2.2 times lower than that detected in linguae.
The zygomatic arch is robust and provides a large area for attachment of the masseter muscle.
Cysticerci were recovered from the heart, tongue, internal masseter, external masseter, triceps brachii, diaphragm, brain, head muscles, psoas and muscles of the forelimbs, hind limbs, head, oesophagus, trunk and abdomen.
