Last - Smell (Olfaction)

Question 1

Comprises the two olfactory organs in the nasal cavity.

Answer 1

Olfactory epithelium

Question 2

The connective tissue beneath the olfactory epithelium.

Answer 2

Lamina propria

Question 3

Columnar epithelial cells found in the olfactory epithelium between the olfactory receptor cells.

Answer 3

Supporting cells

Question 4

Bipolar neurons found in the olfactory epithelium. The dendrite is enlarged into a bulb-shaped “olfactory vesicle” on the surface of the olfactory epithelium.

Answer 4

Olfactory receptor cells

Question 5

It has cilia called “olfactory hairs” which project into the mucus on the surface of the epithelium. Odors cause depolarization on these hairs.

Answer 5

Olfactory vesicle

Question 6

The cells which replace lost or damaged olfactory receptor cells at the base of the olfactory epithelium. They are a notable exception to the rule of thumb that neurons do not replicate.

Answer 6

Basal cells

Question 7

These are mucus glands found in the lamina propria that moisten olfactory epithelium, and dissolve odor molecules.

Answer 7

Bowman’s glands

Question 8

How do you achieve the taste of food?

Answer 8

Result by interaction between the senses of taste and smell, the two senses complement each other and the result is 80% of the taste or flavor of food is smell
