Where are the Odour receptors located?
Odour receptors cells are located in the mucosa high up in the nose (olfactory epithelium). The central processes of the olfactory receptor cells form the olfactory nerve. Olfactory nerves cross cribriform plate and end on the mitral cells of olfactory bulbs. The axons of mitral cells form the olfactory tract and they end upon pre piriform coex and amygdale.
