mandibular nerve in dogs

The motor and sensory nerve subdivision of the trigeminal nerve that transmits sensory information from the auricle, the external acoustic meatus, tympanic membrane, temporal region, the cheek, the skin overlying the mandible, the anterior portion of the tongue, the floor of the mouth, lower teeth and gingiva and transmits motor information from the muscles of mastication, the mylohyoid muscle and digastric muscle and the muscles tensor tympani and tensor veli palatini. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mandibular nerve is

The motor and sensory nerve subdivision of the trigeminal nerve that transmits sensory information from the auricle, the external acoustic meatus, tympanic membrane, temporal region, the cheek, the skin overlying the mandible, the anterior portion of the tongue, the floor of the mouth, lower teeth and gingiva and transmits motor information from the muscles of mastication, the mylohyoid muscle and digastric muscle and the muscles tensor tympani and tensor veli palatini. The atlas records it as a nerve at the organ scale in the dog.

Where the mandibular nerve is

It sits in the head, within the nervous system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the mandibular nerve connects to

The atlas records 12 typed relationships for it, across 5 kinds of connection. part of head and trigeminal nerve.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mandibular nerve. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as inferior maxillary nerve, mandibular division [V3], mandibular division [Vc], mandibular division of fifth cranial nerve, mandibular division of trigeminal nerve [Vc; V3] and mandibular nerve [V3], and 11 more. Searching any of those names reaches this page.

Questions

Where is the mandibular nerve?

What does the mandibular nerve connect to?

Part of: head and trigeminal nerve.

Is the mandibular nerve the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
