Preferred Label : olfactory bulb;
Uberon definition : 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].;
Uberon synonym : bulbus olfactorius;
Uberon related term : olfactory lobe; olfactory lobe (Barr & Kiernan);
Uberon Development note : the olfactory bulbs develop as bilateral evaginations from a region of the prosencephalic
neural plate intercalated between the septal and the cortical anlagen (Cobos et al.
2001b, Rubenstein et al. 1998). Comparing the structure of the olfactory bulb among
vertebrate species, such as the leopard frog and the lab mouse, reveals that they
all share the same fundamental layout(WP).;
Uberon Homology note : The presence of paired evaginated hemispheres and olfactory bulbs in both agnathan
and gnathostome radiations suggests that such hemispheres were also present in the
common ancestor.[well established][VHOG];
Uberon Taxon note : In most vertebrates, the olfactory bulb is the most rostral (forward) part of the
brain. In humans, however, the olfactory bulb is on the inferior (bottom) side of
the brain. The olfactory bulb is supported and protected by the cribriform plate which
in mammals, separates it from the olfactory epithelium, and which is perforated by
olfactory nerve axons. The bulb is divided into two distinct structures, the main
olfactory bulb, and the accessory olfactory bulb;
