|
Olfaction |
Smell |
|
|
Olfactory epithelium |
Occupies the superior part of the nasal cavity, covering the inferior surface of the cribriform plate and extending along the superior nasal concha |
|
|
Olfactory receptors |
First order neurons,bipolar neuron, exposed knob shaped dendrite and an an axon projecting through the cribriform plate and ending in olfactory bulb |
|
|
Olfactory Hairs |
Part of olfactory receptors that respond to inhaled chemicals. Are cilia that project from the dendrite |
|
|
Transduction |
The conversion of stimulus energy into a graded potential in a sensory receptor. |
|
|
Odorants |
Chemicals that have an oder and can therfore stimulate the olfactory hairs |
|
|
Supporting Cells |
are columnar epithelial cells of the mucous membrane lining the nose, provide physical support,nourishment, and the electrical insulation of the olfactory receptors, and help detoxify chemicals that come in contact with the olfactory epithelium |
|
|
Basal Cells |
located between the bases of the supporting cells,continually undergo cell division to produce new olfactory receptors (live for a month or so before being replaced). |
|
|
Olfactory (bowman's) glands |
produce mucus that is carried to the surface of the epithelium by ducts, the secretion moistens the surface of the epithelium and dissolves odorants so that transduction can occur . |
