Sensation or sense of smell and for authors reception occur at the olfactory receptors. The receptors of smell are present at a small patch of "olfactory epithelium" (also known as pseudostratified epithelium) and is located in the upper roof of the nasal cavity. The olfactory epithelium appears to be a little yellowish in color and consists of three types of main cells which ultimately do the function of smell.
1) Olfactory receptor cells: They act as sense or sensory receptors as well as conducting neurons. The olfactory receptor cells are called "unusual" bipolar neurons. Each cell has a spindle shaped structure and has a thin apical dendrite that terminates into a knob which bears non motile cilia called as olfactory hairs. Olfactory cells in their nature are unique and are the only neurons that always undergo the turnover throughout the adult life.
2) Supporting cells and 3) Basal cells.
