A&P II Module 3 Potential Exam Questions
1. what sense does not have specialized sense organs?
Touch
1. What senses contain specialize receptor cells via specialized
somatic and visceral afferents?
Smell and Equilibrium (A&C)
2. the outer fibrous layer of the eye includes thesclera and
cornea
2. The posterior portion of the outer fibrous layer of the eye is called ___.
Sclera
3. which portion of the eye supplies blood supply to other areas of the eye?
choroid (of the middle layer)
3. The middle layer of the eye includes which regions?Ciliary
body and iris
4. true or false: the more numerous type of photoreceptors are
rodsTrue
4. True or false: Cones operate best in dim light.False
5. what is the correct order of how light travels through the eye?
cornea, lens, vitreous fluid, retina
5. What is the correct order of how light passes through the eye?
Cornea, Aqueous, Humor, lens, retina
6. 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
, lOMoAR cPSD| 67691079
Bilateral left visual field blindness. The right optic tract is damaged. All the
sensory information from the left visual fields travel together after the optic
chiasm to the right side of the brain.
6. A patient is found to have blindness of the right visual field of both eyes.
what part of the vision pathway was most likely damaged? explain your
answer
The Left Lateral Geniculate Nucleus. All of the sensory information from the
right visual fields travels together after the optic chiasm to the left side of the
brain
7. A patient is found to have blindness in the right eye. what part of the
vision pathway was most likely damaged? explain your response
The right optic nerve. Information from the right visual field has not yet
crossed at the optic chiasm. both peripheral and nasal fields of the right eye
would be missing
7. A patient has a brain tumor in the area indicated by the red X in the
figure below. What type of blindness is the patient mostly likely to incur.
Explain your reasoning.
, lOMoAR cPSD| 67691079
Left eye blindness because there is damage to the left optic nerve. Information
from the left visual field has not yet crossed at the optic chiasm. Both
peripheral and nasal fields of the left eye would be missing.
8. True or false: the lateral fibers of the optic nerve cross at the optic
chiasmFalse
9. The _______ is controlled by the abducens nervelateral rectus
9. The __ is controlled by the trochlear nerve.Superior Oblique
10. Your elderly patient is discussing her vision problems. She
describes her vision as blurry. Her left eye deviates medially when
looking straight ahead. what is most likely causing the vision
problem?
Damage to the abducens nerve which is responsible for controlling the lateral
rectus. This type of damage would cause a muscle imbalance meaning the
medial rectus would pull the eye medially when looking straight ahead causing
diplopia.
