olfactory bulb

A bulbous anterior projection of the olfactory lobe that is the place of termination of the olfactory nerves and is especially well developed in lower vertebrates (as fishes)[BTO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the olfactory bulb is

A bulbous anterior projection of the olfactory lobe that is the place of termination of the olfactory nerves and is especially well developed in lower vertebrates (as fishes)[BTO]. The atlas records it as a nerve at the organ scale in the human body.

Where the olfactory bulb is

It sits 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 olfactory bulb connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of material anatomical entity and telencephalon.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the olfactory bulb. 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 bulbus olfactorius, bulbus olfactorius (Morgagni), olfactory lobe and olfactory lobe (Barr & Kiernan). Searching any of those names reaches this page.

Questions

Where is the olfactory bulb?

It sits 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 olfactory bulb connect to?

Part of: material anatomical entity and telencephalon.

Is the olfactory bulb 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.
