Question 8

Why do humans rely very little on pheromones? Which structure in the human olfactory system is not present that is present in other animals that rely on pheromones?

Answer 8

Humans do not have an Accessory Olfactory Bulb. Without an Accessory Olfactory Bulb, pheromones cannot be processed by the brain as effectively as an animal that does have an accessory olfactory bulb (ex: a mouse).

Question 9

Why is that when one has a cold and their nose is stuffy, their sense of taste is diminished?

Answer 9

When someone eats, molecules travel to the back of the throat and nose, so when eating one’s sense of taste is being used in conjunction with one’s sense of smell. When someone has a cold, their sense of smell is knocked out, therefore diminishing their sense of taste.

Question 10

What is the common name for olfaction?

(A) Smell
(B) Taste
(C) Hearing

(A) Glomerulus
(B) Filiform Papillae
(C) Mitral Cell
(D) Olfactory Bulb

Answer 12

(D) Olfactory Bulb

The Olfactory Bulb is a bundle of nerves that lie right above the cribriform plate. The Olfactory Bulb sends little nerve projections through the cribriform plate to the olfactory epithelium.

Question 13

True or False? At the end of each projection that the olfactory bulb sends through the cribriform plate to the olfactory epithelium, there are receptors that are sensitive to many molecules each.

Answer 13

False. At the end of each projection that the olfactory bulb sends through the cribriform plate to the olfactory epithelium, there are receptors that are sensitive to ONLY 1 MOLECULE each.

Question 14

The cribriform plate of the ethmoid bone has many holes. What would happen if the cribriform plate were completely solid (no holes)?

Answer 14

Without holes, it would be much tougher for nerves from the olfactory bulb to connect to the olfactory epithelium. Without these nerve receptors present, the sense of smell would be impaired.

(A) I -> II -> III -> IV
(B) IV -> III -> II -> I
(C) IV -> II -> III -> I
(D) I -> III -> II -> IV

Answer 17

(D) I -> III -> II -> IV

Odor molecule binds to specific G-Protein Coupled Receptor (GPCR) in the olfactory epithelia -> G-Protein dissociates from Receptor -> G-Protein actions activate an ion channel which allows cations to enter through the membrane, and triggers and Action Potential -> Action potential travels through the Cribriform Plate to the Glomerulus

Question 18

CRB True or false? Olfaction is the only sense that does not pass through the thalamus.

Answer 24

(C) Each taste bud is composed of multiple cells, that combine to sense the 5 flavors.

Each taste bud is composed of multiple cells, that combine to sense the 5 flavors. Because of this, any flavor can be tasted on any part of the tongue!

Question 25

Considering the proximity of the receptors for different flavors. How does the Labelled Lines Model account for the 5 flavors not mixing?

Answer 25

The Labelled lines model says that each axon in a tastebud is separated by cell type, and different cell types’ axons never converge or mix.

(A) Salty, Sour
(B) Bitter, Sweet
(C) Sweet, Umami
(D) Bitter, Umami

Answer 27

(A) Salty, Sour

Salty and Sour taste cells rely on Ion Channels.

Question 28

Compare and Contrast the function of G-Protein Coupled receptors and Ion Channels in terms of the Gustatory System?

Answer 28

GPCR: A sweet, umami or bitter molecule binds a GPCR which causes a conformational change. The G-protein then dissociates which opens an ion channel and thus causes the cell to depolarize and fire an Action Potential.

Ion Channel: A sour or salty molecule binds to a receptor on an Ion channel which opens causing the cell to depolarize and fire an Action Potential

Question 29

When an Ion channel opens due to receptor binding, do cations or anions flow into the cell, causing depolarization?

Answer 29

Cations. When a molecule binds to a receptor on an ion channel, the ion channel opens and +ions begin to flow in, causing depolarization, and an action potential.

Question 30

If a salt receptor was accidentally expressed and activated in a sweet cell, would the sensed taste in the brain be salty or sweet? Why?

Answer 30

Sweet. Because of the Labelled Lines Model, the type of cell activated will determine the sensed taste, not the receptor activated.

In REM sleep, the activity of the prefrontal cortex in the brain decreases. The prefrontal cortex is responsible for logical thinking, therefore our dreams in REM sleep can defy logic and not seem strange.

Question 59

Compare the Activation-Synthesis Dream Hypothesis to the Freud Dream Theory.

Answer 59

Activation-Synthesis: In REM sleep, the brainstem is active and the cerebral cortex will later make sense of it. Dreams are a result of random firing in the brain.
