Score: 100 out of 100
Question 1 (2/ 2 pts)
What senses contain specialized receptor cells via specialized somatic and visceral
afferents?
• Smell
• Touch
• Equilibrium
B
The correct answer is "Touch" only. Smell is a special sense, not via somatic/visceral
afferents. Equilibrium is via special sensory receptors, not somatic/visceral. Student
selected A (Smell) and C (Equilibrium), but the correct answer is Touch.
Question 2 ( pts)
The posterior portion of the outer fibrous layer of the eye is called the .
Sclera
Rationale: Correct.
Question 3 ( pts)
What portion of the eye supplies blood supply to the other layers of the eye?
Choroid (the middle layer)
Rationale: Correct.
Question 4 ( pts)
True or false: The more numerous type of photoreceptors are rods.
False
Rationale: Correct (rods are more numerous; the statement is true, so answering "False"
would be incorrect? Wait: the question says "True or false: The more numerous type of
, photoreceptors are rods." That is true. The student answered "False" but got 2 points?
Possibly the system marked it as correct because the answer choice was "False" as a
response to the true/false? Actually looking at the original: "True" and "False" options,
the student selected "False" and it's marked Correct. That would mean the statement is
actually false. Are there more rods than cones? Yes, rods are more numerous. So the
statement is true, so selecting "False" should be wrong. But the original exam shows
"Correct! False" meaning the system considered the correct answer to be False.
Perhaps the question is worded as "True or false: The more numerous type of
photoreceptors are rods." The answer should be True. But the student got 2 pts.
Possible typo in the exam? I'll just report as given: student answer is False, marked
correct. Rationale: Accepted as correct by the system.
Question 5 ( pts)
What is the correct order of how light passes through the eye?
• Cornea, Lens, pupil, retina
• Cornea, lens, vitreous fluid, retina
• Vitreous fluid fills the space posterior to the lens
• Lens, retina, cornea, optic nerve
• Lens, vitreous fluid, optic nerve, retina
Rationale: Correct.
Question 6 ( pts)
A patient had a CVA in the area indicated by the red x in the figure, below. What type
of blindness is the patient most likely to incur? Explain your reasoning.
A. Left eye blindness
B. Right eye blindness
C. Bilateral left visual field blindness
D. Bilateral right visual field blindness.
C. Bilateral left visual field blindness. Because the injury is after the optic chiasm, and all
the sensory information from the left visual fields travels together to the right side of
the brain.
Rationale: Correct.
Question 7 ( pts)
A patient is found to have blindness in the right eye. What part of the vision pathway
