D. A&C
The posterior portion of the outer fibrous layer of the eye is called the _____. Correct Ans - Sclera
What portion of the eye supplies blood supply to the other layers of the eye? Correct Ans - Choroid (of the middle layer)
True or false: The more numerous type of photoreceptors are rods. Correct Ans - True
What is the correct order of how light passes through the eye? Correct Ans - A. Cornea, Lens, pupil, retina
B. Correct! Cornea, lens, vitreous fluid, retina Vitreous fluid fills the space posterior to the lens
C. Lens, retina, cornea, optic nerve
D. Lens, vitreous fluid, optic nerve, 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. Correct Ans - 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 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. Correct Ans - Left eye blindness
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. Correct Ans - False
only medial fibers cross at optic chiasm
The ________ is controlled by the trochlear nerve. Correct Ans - A. Superior rectus
B. Medial rectus
C. Lateral rectus
What sense does not have specialized sense organs? Correct Ans - A. Smell
B. Correct! Touch
C. Equilibrium
D. A&C
