vomeronasal organ in dogs

An organ thought to supplement the olfactory system in receiving pheromonic communication. The sensory part of the organ is in two long, thin sacs, situated on either side of the nasal septum at its base. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the vomeronasal organ is

An organ thought to supplement the olfactory system in receiving pheromonic communication. The sensory part of the organ is in two long, thin sacs, situated on either side of the nasal septum at its base. The atlas records it as a sense organ at the organ scale in the dog.

Where the vomeronasal organ is

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

What the vomeronasal organ connects to

The atlas records 10 typed relationships for it, across 7 kinds of connection. part of nose and olfactory system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the vomeronasal organ. 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.
