PHYII EXAM /LATEST UPDATES/ QUESTIONS AND CORRECT
ANSWERS WITH VERIFIED SOLUTIONS.
Which cranial nerves carry special sensory fibers for taste? - ANSWER: VII
Facial
IX Glossopharyngeal
X Vagus
Which cranial nerves carry special sensory fibers for smell? - ANSWER: I
Olfactory
Which embryonic vesicle gives rise to the olfactory pathway? - ANSWER:
telencephalon
The sense of smell evolved into the _____ system. - ANSWER: Limbic, so very
tied to emotions and food selection
Which of the following are NOT characteristics of smell?
Volatile
Low threshold
Rapid adaptation
Qualitative and affective
Quantitative - ANSWER: Smell is not Quantitative
, What happens in transduction during smell? - ANSWER: Odorant binds to hair
cell, activates G-Protein and cyclic AMP. Amplifies the stimulus
Which of the following cells is NOT found on the outside of the olfactory bulb in
the nasal cavity ? - ANSWER: Bowman's Cell
Sustentacular Cells
Bipolar neurons
Granule Cells .
Which of the following cells is NOT found in the inside of the olfactory bulb in the
nasal cavity ?
Mitral and tufted cell
Juxtagolmerualar cells
Granule Cells
Bowman's Cells - ANSWER: Bowman's Cells
What is the site of synapse between bipolar olfactory neurons and Mitral/Tufted
cells. Different glomeruli respond to different odors? - ANSWER: Glomeruli
T or F: Bipolar olfactory nerves have hair receptors (cilia) on peripheral end which
an odorant can bind to. The central processes of bipolar cells go through the
cribriform plate to synapse on cells in olfactory bulb.
2) Mucus is made by Bowman's cells/glands. - ANSWER: True
What does the very old CNS pathway do? - ANSWER: Basic reflexes, including
pheromones
