nasal cavity in dogs

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 dog.

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 19 typed relationships for it, across 10 kinds of connection. part of nose and upper respiratory tract.

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.
