Portage Learning Anatomy & Physiology 2: Module 3 Exam
1. B. Touch: What sense does not have specialized
sense organs?
A. Smell
B. Touch
C.EquilibriumD. A&C
2. Sclera: The posterior portion of the outer fibrous layer of the eye is called the _____.
3. Choroid (of the middle layer): What portion of the eye supplies blood supply to the
other layers of the eye?
4. True: True or false: The more numerous type of photoreceptors are rods.
5. B. Cornea, lens, vitreous fluid, retina Vitreous fluid fills the space posterior to the
lens
(Vitreous fluid fills the space posterior to the lens): What is the correct order of how
light passes through the eye? A. Cornea, Lens, pupil, retina
B.Cornea, lens, vitreous fluid, retina
C. Lens, retina, cornea, optic nerve
D. Lens, vitreous fluid, optic nerve, retina
6. Bilateral left visual field blindness
The right optic tract is damaged. All the sensory information from the left visual fields
travels together after the optic chiasm to the right side of the brain.: 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.
7. Left eye blindness
1/8
, Portage Learning Anatomy & Physiology 2: Module 3 Exam
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.:
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 most likely
to incur? Explain your reasoning.
8. False (only medial fibers cross at optic chiasm): True or False: All sensory information
from the optic nerves cross at the optic chiasm.
9. D. Superior oblique: The ________ is controlled by the trochlear nerve.
A. Superior rectus
B.Medial rectus
C. Lateral rectus
D. Superior oblique
10. B
The abducens nerve controls the lateral rectus. Damage to the lateral rectus would cause
there to be a muscle imbalance, and the medial rectus would pull the eye medially when
looking straight ahead, causing blurry vision. (Diplop-
ia): Your elderly patient is discussing her vision problems. She describes her vision as blurry.
Following a visual examination, her left eye deviates medially when looking straight ahead.
What is most likely causing the vision problem? Explain your reasoning.
A. Cataracts
B.Abducens nerve damage
C. Brain tumor in the occipital lobe
D. Medial rectus damageE. Superior rectus damage
11. label: Match the numbers (1-5) in the figure below with the correct terms (A-H).
Note: not all terms will be used.
1- A: Scala Tympani
2- B: Facial Nerve
3- C: Tympanic Membrane
