Bob is a cat person. His house smells very, VERY strongly of cat litter, but he genuinely can't smell the cat litter. Bob is clearly nose-blind, but says you're gaslighting him. How did that happen?

a)

The cat litter odorants are no longer bonding to his olfactory hair receptor cells

b)

Bob has damage to both his Olfactory nerve and Olfactory Cortex in his Temporal Lobe

c)

After a while in his house, the same odorants of the cat litter scent are still bonded to the olfactory hair receptors in his nose.

Bob is right. You are gaslighting him. What cat litter smell?

Order the steps of OLFACTION (Smell):

1) Odorants bind to Olfactory hair receptors in olfactory epithelium

2) CN I (Olfactory) crosses through olfactory foramina & enters Olfactory Bulb

3) Signals reach Olfactory Cortex in Temporal Lobe & Limbic System (Emotional Brain)

4) Odorants (substances in a solution we smell) enter the NASAL CAVITY

5) 2nd Action Potential triggered & travels along Olfactory Tract

6) You can SMELL! YAY! It's your grandpa's favorite cologne!

7) Triggers Action Potential in Olfactory Nerve (CN I)

a)

4, 7, 1, 2, 5, 3, 6

b)

6, 7, 1, 2, 5, 3, 4

c)

1, 2, 3, 4, 5, 6, 7

d)

4, 1, 7, 2, 5, 3, 6

102.

Damage to the olfactory receptors would MAINLY cause:

a)

Loss of vision

b)

Loss of smell

c)

Loss of taste

d)

Loss of fun

103.

Which structure carries sensory input/SENSATION for hearing andbalance

a)

CN III- Oculomotor

b)

CN VI- Abducens

c)

CN VIII- Vestibulocochlear nerve

d)

CN I- Olfactory Nerve

104.

Order the steps of GUSTATION (Taste):

1) Tastants (Substances we taste in a solution)

2) Facial CN-VII (anterior 2/3 of tongue), Hypoglossal CN-IX, Vagus CN-X send action potential to the solitary nucleus of the BRAIN STEM

3) Travels to Ventral posterior medial nucleus of Thalamus

4) Travels to hypothalamus & Amygdala

5) Gustatory RECEPTORS in the Taste buds found on the tongue get stimulate

6) Travels to the GUSTATORY CORTEX in the Insula Lobe

a)

1, 2, 5, 4, 3, 6

b)

1, 2, 4, 4, 3, 6

c)

1, 5, 2, 4, 3, 6

d)

1, 2, 3, 4, 3, 6
