mandibular nerve

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 human body.

Where the mandibular nerve is

It sits in the head, within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the mandibular nerve connects to

The atlas records 21 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?

It sits in the head, within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the mandibular nerve connect to?

Part of: head and trigeminal nerve.

Is the mandibular nerve the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
