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 other 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?
A. Cornea, Lens, pupil, retina
B. 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 - correct answer 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 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
, 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 False
only medial fibers cross at optic chiasm
The ________ is controlled by the trochlear nerve.
A. Superior rectus
B. Medial rectus
C. Lateral rectus
D. Superior oblique - correct answer A. Superior rectus
B. Medial rectus
C. Lateral rectus
D. Correct! 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.
A. Cataracts
B. Abducens nerve damage
C. Brain tumor in the occipital lobe
D. Medial rectus damage
E. Superior rectus damage - correct answer 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. (Diplopia)
Match the numbers (1-5) in the figure below with the correct terms (A-H).
Note: not all terms will be used. - correct answer 1- A: Scala Tympani
2- B: Facial Nerve
3- C: Tympanic Membrane
4- D: Cochlear duct
5- E: Organ of Corti
Which of the following statements is false regarding the external ear?
A. The lobule does not contain cartilage.
B. The auricle funnels sound into the external acoustic meatus.
C. The helix contains cartilage.
D. The external acoustic meatus travels through the parietal bone. - correct answer A.
The lobule does not contain cartilage.
B. The auricle funnels sound into the external acoustic meatus.
C. The helix contains cartilage.
D. Correct! The external acoustic meatus travels through the parietal bone.
