PSYB51H3 Chapter Notes - Chapter 15: Taste Bud, Olfactory Mucosa, Taste Receptor
Document Summary
Taste: taste v. flavor, taste sensation evoked by solutions in the mouth that contact receptors on the tongue and the roof of the mouth that then connect to axons in cranial nerves. Some of the cells in a taste bud have specialized sites on their apical projections that interact with taste stimuli. Some of the cells form synapses with taste nerve fibers: taste buds are house in structures call papillae any of multiple structures that give the tongue its bumpy appearance. The ofc is responsible for the conscious experience of olfaction, as well as the integration of pleasure and displeasure from food; it has been referred to as the secondary olfactory cortex and secondary taste cortex. The ofc is also involved in many other functions, and it is critical for assigning affective value to stimuli---in other words, determining hedonic meaning. Some cations also produce other taste qualities (e. g. potassium taste bitter and salty).
