masseter muscle in dogs

Pharyngeal arch 1 muscle that participates in oral/pharyngeal behaviors, is innervated by masseteric nerve branches of the trigeminal nerve (CN V), and attaches to mandible and zygomatic arch. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the masseter muscle is

Pharyngeal arch 1 muscle that participates in oral/pharyngeal behaviors, is innervated by masseteric nerve branches of the trigeminal nerve (CN V), and attaches to mandible and zygomatic arch. The atlas records it as a muscle at the organ scale in the dog.
