What senses contain specialized receptor cells via specialized somatic and visceral afferents? - CORRECT
ANSWER -smell & equilibrium ( a&c)
the posterior portion of the outer fibrous layer of the eye is called the ____ - CORRECT ANSWER -sclera
what portion of the eye supplies blood supply to the outer layers of the eye? - CORRECT ANSWER -
choroid (of the middle layer)
true or false: the more numerous type of photoreceptors are rods - CORRECT ANSWER -true
what is the correct order of how light passes through the eye? - CORRECT ANSWER -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. - CORRECT ANSWER -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 ANSWER -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
ANSWER -F
, The ________ is controlled by the trochlear nerve. - CORRECT ANSWER -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. - CORRECT ANSWER -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.
