Document Summary
Chapter 4 sensation: smell must know for final. Olfactory epithelium: a mucous membrane at the top of nasal cavity; contains the olfactory receptor neurons that respond to airborne molecules called odorants. Glomeruli: sites in the brain"s olfactory bulb where signals from the smell receptors converge. Each type of odorant binds more easily to some types of receptors than others, so we can think of each type of receptor as having. Smell has many functions like our flavor- odorants can reach nasal cavity through nose and that"s how we smell food! Like there was this experiment where they wiped down women"s armpits and made other women smell it and there was synchrony: taste. For smell, the molecules we call odorants are carried through the air . In contrast molecules called tastants are carried through fluids not by air. Smell located in olfactory epithelium at top of nose, taste receptors located on tongue.
