The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Each osn expresses only 1 of approximately 1,200 odor receptors (ors). Web however, studies have suggested that although the relative olfactory bulb size and the number of olfactory receptor coding genes fall behind those of rodents, humans have an olfactory system with complex networks and pathways that allow us to perform as well as or even better than some other mammals [ 2 ]. Olfactory receptors (ors) form the most important chemosensory receptor family responsible for our sense of smell in the nasal olfactory epithelium. Web the axons of the bipolar orns pass through small foramina (natural openings) in the cribriform plate joined together in fascicles (bundles), where they synapse in intricate neural masses called glomeruli in the olfactory bulb.
Each osn expresses only 1 of approximately 1,200 odor receptors (ors). The nerve fibre layer of the olfac tory bulb), the basal lamina coverings of the fascicles fuse with that of the glia limitans. Olfactory receptors (ors) form the most important chemosensory receptor family responsible for our sense of smell in the nasal olfactory epithelium. The primary olfactory pathway consists of orns in the oe whose axons project through the cribriform plate to synapse with cells in the olfactory bulb in the central nervous system (cns).
During a waiting period of several days, olfactory axons arrive and accumulate outside the cns while the bulb differentiates beneath them. Each orn axon innervates only a single glomerulus. These fascicles leave the nasal cavity, pass through the lamina cribrosa of the ethmoid bone and enter the brain.

Web sensory axons extend from the chick olfactory epithelium to the telencephalon well before the maturation of their target, the olfactory bulb. These axol'ls are thin and unmyelinated and form fascicles that are surrounded by a single schwann cell. Web olfactory information is further processed in higher brain regions, such as the anterior olfactory nucleus (aon), the olfactory tubercle (ot), entorhinal cortex (ent), piriform cortex (pir), and cortical amygdala (coamg).
