A&P 2 module 3 exam - portage learning
1.What senses contain specialized receptor cells via specialized somatic and visceral afferents?: smell & equilibrium ( a&c)
2.the posterior portion of the outer fibrous layer of the eye is called the ____: sclera
3.what portion of the eye supplies blood supply to the outer layers of the eye?: choroid (of the middle layer)
4.true or false: the more numerous type of photoreceptors are rods: true
5.what is the correct order of how light passes through the eye?: cornea, lens, vitreous fluid, retina
6.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.: 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.
7.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.: 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.
8.True or False: All sensory information from the optic nerves cross at the optic chiasm.: F
9.The ________ is controlled by the trochlear nerve.: Superior oblique
10. 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.: 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.
11. 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: 1- A: Scala Tympani
2- B: Facial Nerve
3- C: Tympanic Membrane
4- D: Cochlear duct
5- E: Organ of Corti
