Taste and Smell

Question 1

Olfaction

Answer 1

The sense of smell; it is correlated with the sense of taste

Question 2

Olfactory Epithelium

Answer 2

The area of the nostril

Question 3

Olfactory Bulb

Answer 3

A bundle of nerves that have branching endpoints with receptors that are specific to one type of molecule

Question 4

Cribriform Plate

Answer 4

A plate that separates the olfactory epithelium from the brain

Question 5

Pheromones

Answer 5

Species-specific molecules that are detected by other animals through smell

Question 6

Accessory Olfactory Epithelium

Answer 6

A specialized olfactory epithelium in animals for detecting pheromones

Question 7

Vomeronasal system

Answer 7

A system of the accessory olfactory epithelium consisting of basal and apical cells, were basal cells send signals through an accessory olfactory bulb to the amygdala

Question 8

Label-line Theory of Olfaction

Answer 8

Each receptor responds to specific stimuli and is linked directly to the brain

Question 9

Vibrational Theory of Olfaction

Answer 9

The vibrational frequency of a molecule gives its odor profile

Question 10

Steric/Shape Theory of Olfaction

Answer 10

Each molecule fits in a specific receptor

Question 11

Anosmia

Answer 11

The inability to smell

Question 12

Gustation

Answer 12

The sense of taste

Question 13

Taste buds

Answer 13

Taste receptor cells on the tongue that can be located in the anterior, side, or back. Each taste bud has receptors for the five tastes

Question 14

The five tastes

Answer 14

Sweet, sour, bitter, salty, umami

Question 15

Label Line Model of Gustation

Answer 15

Each of the five taste receptors have their own axon that synapses at a unique location in the gustatory cortex in the brain
