Document Summary
The male was rubbing his face towards a tree. Female smells that, and when it encounters the actual male, she has to make sure the male is the one left the odor marks. Olfactory receptor cells have the highest turnover of any sensory cells. Triggers cascade of events/open a channel to allow other ions to pass through molecule binding to receptor. Oldest form: basic mechanism involved in regulating a wide variety of processes. Bent by a particle of a near-field sound. Pores inside the hair to allow odor molecules to diffuse inside. Often surrounded by a kind of liquid that the molecule must diffuse through before they can really enter to the receptors in the membrane. Surrounds the cilia, and allow the molecules to diffuse through. Olfactory cells may be narrowly tuned to a single chemical. 1 cell class sensitive to a single odor. Binds onto the receptor cells, and transfer to the glomeruli.
