AVE at 10 Hz produced deep masseter muscle relaxation and finger warming within six minutes.
2.
Unlike hystricomorphous and myomorphous rodents, the medial masseter muscle does not pass through the infraorbital canal.
3.
The masseter muscle does attach directly behind the zygomatic arch in a manner very different from sciuromorphs.
4.
Here the nerve stimulator can be used in identifying the donor motor nerve to the masseter muscle.
5.
The skull is protrogomorphous; it has no specialized attachments for the masseter muscles as seen in other rodents.
6.
A sciuromorphous zygomasseteric system is characterized by attachment of the lateral masseter muscle along the side of the rostrum.
7.
The infraorbital canal is enlarged, presumably allowing for the passage of the medial masseter muscle as with other hystricomorphs.
8.
Conversely, while a masseter muscle can be large due to congenital reasons, it can commonly be an acquired deformity.
9.
The parotid duct, a long excretory duct, emerges from the front of each gland, superficial to the masseter muscle.
10.
The insertion joins the masseter muscle to form a common tendinous sling which allows the medial pterygoid and masseter to be powerful elevators of the jaw.
