| development_notes |
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). |

| external_definition |
Segment of neural tree organ which is continuous with a set of olfactory nerves and an olfactory tract[FMA:77624]. Part of the telencephalon comprised of anterior outgrowths of either of the cerebral hemispheres in which the olfactory nerve exits.[AAO] The part of the forebrain in which the olfactory nerves end and the olfactory tracts originate. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG] Part of the rostral part of the cerebrum where axons of olfactory cells from the nasal mucosa terminate. Projects onto olfactory parts of pallium via olfactory tracts |

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 Note that in uberon 'main olfactory bulb' is a separate class, but some ontologies may treat this as partially synonymous. The distinction may only make sense in tetrapods with a vomeronasal organ (olfactory nerves terminate in OB in fishes and in main OB in tetrapods - Butler and Hodos) |
