Study Notes
Olfactory Epithelium
- The approximate area of the olfactory epithelium in adult humans is around 10 square centimeters.
- Olfactory chemoreceptors for the sense of smell are located on the surface of olfactory receptor neurons in the olfactory epithelium.
- The thickness of the olfactory epithelium in adult humans is approximately 30-100 micrometers.
- Bipolar neurons are present throughout the olfactory epithelium.
- The cilia of olfactory neurons provide a large surface area for odorant binding, allowing for effective detection of odor molecules.
