A&P 2 MODULE 3 EXAM - PORTAGE
LEARNING EXAM QUESTIONS AND
ANSWERS (VERIFIED AND UPDATED)
What senses contain specialized receptor cells via specialized somatic and visceral afferents? -
ANS smell & equilibrium ( a&c)
the posterior portion of the outer fibrous layer of the eye is called the ____ - ANS sclera
what portion of the eye supplies blood supply to the outer layers of the eye? - ANS choroid
(of the middle layer)
true or false: the more numerous type of photoreceptors are rods - ANS true
what is the correct order of how light passes through the eye? - ANS cornea, lens, vitreous
fluid, retina
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. - ANS Bilateral left visual
field blindness.
The right optic tract is damaged. All the sensory information from the left visual fields travels

, 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. - ANS 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.
True or False: All sensory information from the optic nerves cross at the optic chiasm. - ANS F
The ________ is controlled by the trochlear nerve. - ANS Superior oblique
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. - ANS 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.
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
4- D: Cochlear duct
5- E: Organ of Corti - ANS 1- A: Scala Tympani
2- B: Facial Nerve
3- C: Tympanic Membrane
4- D: Cochlear duct
5- E: Organ of Corti
Match the numbers (1-5) in the figure below with the correct terms (A-H). - ANS 1.) facial
nerve
2.) malleus
