Olfactory bulb anatomy. Artwork of a human nose, showing the anatomy of the olfactory bulb, the organ of smell. This lies above the anterior aspect of the nasal cavity on the ethmoid bone. Nerve extensions of the bulb protrude through the bone to the nasal cavities, where circulating odour molecules (blue) bind to receptors and convey signals to the brain's cerebral cortex. The inset at centre shows the olfactory receptor neurons (red) and their receptors, as well as the olfactory mucosa and epithelium. The inset at upper right shows the glomeruli (round) in the olfactory bulb, and the olfactory bulb mitral cells (red and blue).
