maxillary nerve

The sensory nerve subdivision of the trigeminal nerve that transmits sensory information from the palate, upper teeth and gingiva, the skin between the palpebral fissure and the mouth, and from the nasal cavity and maxillary sinuses. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the maxillary nerve is

The sensory nerve subdivision of the trigeminal nerve that transmits sensory information from the palate, upper teeth and gingiva, the skin between the palpebral fissure and the mouth, and from the nasal cavity and maxillary sinuses. The atlas records it as a nerve at the organ scale in the human body.

Where the maxillary 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 maxillary nerve connects to

The atlas records 15 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 maxillary 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 maxillary division [V2], maxillary division [Vb], maxillary division of fifth cranial nerve, maxillary division of trigeminal nerve (Vb; V2), maxillary nerve [V2] and maxillary nerve [Vb], and 10 more. Searching any of those names reaches this page.

Questions

Where is the maxillary 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 maxillary nerve connect to?

Part of: head and trigeminal nerve.

Is the maxillary 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.
