Question 1
A few sensory receptors are listed below. Select each one that is NOT a neuron, but is instead a modified epithelial cell. This question has multiple correct answers.
Answer Choices:
olfactory sensory neuron
mitral cell
vallate papillae
fungiform papillae
Question 2
Gustatory epithelial cells are excited by _________________ .
Answer Choices:
action potentials of the olfactory nerve filaments
the taste buds with undissolved chemicals
binding of tastants to receptors on their microvilli
binding of odorants to receptors on their microvilli
Question 3
Olfactory pathways to the brain are associated with which of these?
Answer Choices:
Mitral cells in the olfactory bulb
Inferior colliculi
Optic chiasma
None of the above
Question 4
Put the following items into the order from the odorant molecule arriving to sending olfactory information to the rest of the brain.
olfactory tract
mitral cell activation
olfactory receptor neuron axon activation
cribiform plate of the ethmoid bone
olfactory epithelium
glomeruli
Question 5
Smell transduction and taste transduction share which of the following in common?
Answer Choices:
In reality these transduction pathways share nothing in common.
Olfactory bulbs
Mitral cells
Both could involve a pathway which includes G protein.
Question 6
When someone has a common cold they experience a loss of appetite. The best explanation is _______________________ .
Answer Choices:
what we think of as taste is mainly smell
the nasal congestion caused by the cold failed to block access to olfactory receptors
tastants are no longer dissolved in saliva due to dry mouth
odorants can no longer be drawn into the nose by sniffing
Question 7
Which cranial nerves are involved in the physiology of taste?
Answer Choices:
II
XI
II, IV and VI
VII, IX and X
Question 8
Which of the following conditions is ordinarily indicated when olfactory neurons lose their ability to replace themselves?
Answer Choices:
mild depression
inflammatory response to an allergy
age related anosmia
antibiotics killed all the olfactory neurons at once
Question 9
Which submodality of taste is sensitive to the pH of saliva?
Answer Choices:
sweet
sour
bitter
salty
Question 10
Every sensory receptor has to produce a generator potential to activate the next cell in its pathway (or itself). The sensory receptors for the somatic senses are true neurons, with their cell bodies typically within the dorsal root ganglia. Meanwhile, the only special senses receptor that is a true neuron with an axon is the [3]. For example, taste cells are [4] that exist entirely within the [5]. Each sensory receptor is activated by specific stimuli, so that [6] are activated within the cochlea by a [7] that causes a [8] of their hairs, while [9] in the semicircular canals are activated by [10] that causes [11] to push on their hairs. Some sensory receptors can only be [12] by their stimuli, while others, like the vestibular sensory receptors, can be [13] by their stimuli. When a sensory receptor does not have an axon, it has to synapse onto a neuron in order to send the information back to the [14]. For example, a taste cell for sweet tastes will most likely synapse onto a sensory neuron that will carry the information back through the [15] nerve.
