nasal cavity

An anatomical cavity that is part of the olfactory apparatus. This includes the space bounded anteriorly by the nares and posteriorly by the choanae, when these structures are present. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the nasal cavity is

An anatomical cavity that is part of the olfactory apparatus. This includes the space bounded anteriorly by the nares and posteriorly by the choanae, when these structures are present. The atlas records it as a cavity at the organ scale in the human body.

Where the nasal cavity is

It sits in the head, within the respiratory and sensory systems. Positioned deliberately as part of this species body plan.

What the nasal cavity connects to

The atlas records 12 typed relationships for it, across 8 kinds of connection. part of olfactory apparatus chamber.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the nasal cavity. 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.

Questions

Where is the nasal cavity?

It sits in the head, within the respiratory and sensory systems. Positioned deliberately as part of this species body plan.

What does the nasal cavity connect to?

Part of: olfactory apparatus chamber.

Is the nasal cavity 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.
