Transcript
The olfactory epithelium. A. The olfactory epithelium contains sensory neurons interspersed with supporting cells as well as a basal layer of stem cells. Cilia extend from the dendrite of each neuron into the mucus lining the nasal cavity. An axon extends from the basal end of each neuron to the olfactory bulb. B. A scanning electron micrograph of the olfactory epithelium shows the dense mat of sensory cilia at the epithelial surface. Supporting cells (S) are columnar cells that extend the ful depth of the epithelium and have apical microvilli. Interspersed among the supporting cells are an olfactory sensory neuron (O) with its dendrite and Taste: cilia and a basal stemSenses, cell (B).Principles (Reproduced, with permission, from Morrison and Costanzo 1990.)
