1

chemoreception

capability to detect and distinguish chemicals in the air we breathe (smell) and in substances we ingest (taste)

2

pheromones

secreted by other individuals, to trigger social and or behavioral responses (sometimes odorless)

3

taste sense

sweet, umami, salty: beneficial
bitter, sour: toxic

4

olfaction

sense of smell (odorants in the air)

5

gustation

sensation of taste (tastants in the foods)

6

olfactory receptors are found upon

bipolar neurons

7

taste receptors are found upon

modified epithelial cells

8

any one receptor appears to respond to

more than just one odorant

9

any one odorant appears to stimulate

more than one receptor

10

combinatorial pattern

array of olfactory sensory neurons stimulated by a odorant

11

sweet

calories, energy

12

umami

protein

13

salty

Na

14

bitter

toxins

15

sour

acidity

16

flavor

combination of inputs from the gustatory, olfactory, and somatosensory systems

17

taste receptor cells are innervated by a ______ neuron

gustatory
(CN 7, 9, or 10)

18

sweet, umami, and bitter are transduced via apical membrane receptors...

without the need for membrane depolarization
