external naris

A naris that provides one of the small external openings of the head that give passage to air for breathing. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the external naris is

A naris that provides one of the small external openings of the head that give passage to air for breathing. The atlas records it as a organ at the organ scale in the human body.

Where the external naris is

It sits in the head, within the sensory 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 external naris connects to

The atlas records 10 typed relationships for it, across 6 kinds of connection. part of head, nose and olfactory system, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the external naris. 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 naris, external nares, nostril, blowhole, anterior nares and anterior naris. Searching any of those names reaches this page.

Questions

Where is the external naris?

It sits in the head, within the sensory 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 external naris connect to?

Part of: head, nose, olfactory system and external nose.

Is the external naris 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.
