To write:
The three types of cells found in the olfactory epithelium and their functions.
Introduction:
The olfactory epithelium works as sensory system. The olfactory epithelium primarily consists of three cells: olfactory sensory neurons, basal cells, and sustentacular or supporting cells. The sensory neurons are basically bipolar neurons which are inserted in supporting cells and their dendrites are emerged above the epithelial cells and ends into bulbous olfactory knob. From this knob immotile cilia are emerged. These cilia are entangled with microvilli and gives larger surface area for odorants. Second are basal cells. These cells are best in reviving the olfactory epithelium. Sustentacular cells are best supporting cells for olfactory epithelium.
