Flashcards in dec1pt1 Deck (17):
1

TRC localized in these three areas

fungiform, foliate, and circumvallate papillae

2

taste buds are located inside

papilla

3

contain many taste buds

circumvallate papilla

4

contains very few taste buds

fungiform

5

more taste buds means the papilla is ___ sensitive

more

6

strucutre of taste bud

taste bed with 50-100 taste recepor cells, basal cells that become TRCs, and supporting cells

7

nature of taste cells

polarized epithelical with voltage gated Ca channels

8

NT of taste cells

seratonin

9

Map for taste located in

cortex

10

two theories of taste

labeled line and crossfiber

11

labeled line theory

TRC of one kind per sensory neuron

12

acrossfiber model

One sensory neuron stim by diffnt cell types

13

difference in two acrossfiber models

TRCs have diffnt proportion taste receptor molecules or have just one but still different types stim one neuron

14

taste cells make synaptic connections with

gustatory nerve

15

trademark of acrossfiber model

each gustatory nerve can respond to different taste modalities

16

more prevalent model

labeled line

17

two broad mechanisms of taste

tastans go through ion channel or activate GPCR
