"The olfactory nerve is the first (CN I) cranial nerve (TA: nervus olfactorius or nervus cranialis I) and is responsible for conveying the sense of smell from the nasal cavity to the brain. Strictly speaking, the term olfactory 'nerve' refers only to the short first order neurones (olfactory filaments) located on the olfactory mucosa. The olfactory bulb, tract and striae are often erroneously referred together as the olfactory nerve, but they are actually an extension of the central nervous system (see olfactory system)."
"The bipolar cell (olfactory sensory neurone, OSN) is the first-order sensory neurone located within the specialised olfactory neuroepithelium, within the 'olfactory cleft' (bounded superiorly by the cribriform plate of the ethmoid bone, medially by the septum and laterally by the superior turbinate) of the nasal cavity. This cell is analogous to the sensory cells of spinal nerves, whose cell bodies reside in the dorsal root ganglion. There are thought to be approximately 6-30 million OSN in humans. Their central processes (axons) form filaments which pass through the cribriform plate, pierce the dura mater and relay in the olfactory bulb. Together, these filaments form the 'olfactory nerve'."
