taste perception Flashcards
Sensory Receptors
Cells within our sense organs(eyes, tongue) that receive and process sensory information
Receptive fields
The area of space in which a receptor can respond to a stimulus
Reception
Tastants are collected by the gustatory hairs and enter the taste pore which stimulate the taste receptors (gustatory cells) in the taste buds that are grounded within papillae
transduction
Gustatory hairs extend from the taste receptors into taste pores and stimulate the taste receptors to convert chemical molecules into electrochemical signals
transmission
Cranial nerves then transmit the electrochemical message to the thalamus
interpretation/perception
The thalamus passes electrochemical message on to the primary
gustatory cortex and the primary gustatory cortex interprets the
sensation
On average, how many taste buds does an individual have
8000-10000 taste buds
What are the bumps on the tongue known as ?
Papillae
In taste buds, how many taste receptors does it contain?
50-150 taste receptors
where are taste buds found
on the tongue, underneath the tongue, the roof and the side of the mouth
what do taste pores do
Taste pores are on the surface of the tongue which open to the taste bus via gustatory hairs
What do gustatory hairs do
They cat as an extension from the receptor to the mouth
