olfactory bulb

n.
The bulblike distal end of the olfactory lobe, where the olfactory nerves begin.

olfactory bulb

Either of two paired, rod-shaped structures arising on the vertebral brain at the base of the frontal lobes, which are supported by the cribriform plate of the ethmoid bone. The cribriform plate’s perforations provide conduits for olfactory nerve processes.
