MeSH Heading: Olfactory Bulb
Tree Number(s): A08.186.211.200.885.388
Unique ID: D009830
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D009830
Annotation: neoplasms: coordinate IM with BRAIN NEOPLASMS (IM) + histological type of neoplasm (IM)
Scope Note: Ovoid body resting on the CRIBRIFORM PLATE of the ethmoid bone where the OLFACTORY NERVE terminates. The olfactory bulb contains several types of nerve cells including the mitral cells, on whose DENDRITES the olfactory nerve synapses, forming the olfactory glomeruli. The accessory olfactory bulb, which receives the projection from the VOMERONASAL ORGAN via the vomeronasal nerve, is also included here.
Entry Term(s): Accessory Olfactory Bulb; Bulbus Olfactorius; Lateral Olfactory Tract; Main Olfactory Bulb; Olfactory Glomerulus; Olfactory Tract
