Sclera and cornea correct Ciliary body and iris Pupil and retina Lens and vitreous fluid Question 3 What portion of the eye supplies blood supply to the other layers of the eye? Choroid (of the middle layer) Question 4 True or false: Cones operate best in dim light. True False correct Question 5 What is the correct order of how light passes through the eye? Cornea, Lens, pupil, retina! Cornea, lens, vitreous fluid, retina correct Vitreous fluid fills the space posterior to the lens Lens, retina, cornea, optic nerve Lens, vitreous fluid, optic nerve, retina This study source was downloaded by 100000830772748 from CourseHero.com on 07-11-2022 15:40:37 GMT -05:00 https://www.coursehero.com/file/66133989/Module-3-Exam-AP-2-BIOD-152pdf/ BIOLOGY QUESTIONS AND ANSWERS 2021/2022 Question 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. A. Left eye blindness B. Right eye blindness C. Bilateral left visual field blindness D. Bilateral right visual field blindness. C. Correct answer 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. Question 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. A. Left eye blindness B. Right eye blindness C. Bilateral left visual field blindness D. Bilateral right visual field blindness. Your Answer Correct answer A 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.

You Answered True Correct Answer False Question 9 The ________ is controlled by the abducens nerve. Superior rectus Medial rectusorrect! Lateral rectus correct answer Superior oblique Question 10 Your elderly patient is discussing her vision problems. She describes her vision as cloudy and dark. Her vision has progressively worsened over the last year. What most likely is causing the vision problem? Explain your reasoning. A. Cataracts B. Cranial nerve damage C. Brain tumor in the occipital lobe D. Medial rectus damage E. Lateral rectus damage A correct answer Cataracts, due to lens that slowly become hardened over time. Light is not able to be refracted onto the retina. Question 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 F: External acoustic meatus G: Cochlear Nerve H: Scala Vestibuli This study source was downloaded by 100000830772748 from CourseHero.com on 07-11-2022 15:40:37 GMT -05:00 https://www.coursehero.com/file/66133989/Module-3-Exam-AP-2-BIOD-152pdf/ Correct! 1 H.

Tympanic Membrane • F. External acoustic meatus Question 12 Which of the following statements is false regarding the external ear? You Answered The lobule does not contain cartilage. The auricle funnels sound into the external acoustic meatus. The helix contains cartilage. Correct Answer The external acoustic meatus travels through the parietal bone.

It is filled with fluid. It is filled with air. Correct answer The malleus receives vibrations from the stapes The stapes receives vibrations from the cochlea. Question 14 Which of the following statements is false regarding the inner ear? The organ of Corti is responsible for the body’s auditory sense It is filled with fluid. The cochlea is responsible for the body’s auditory sense. Correct! There are two semicircular canals which house sensory receptors. Question 15 Place the terms (A-H) in the correct order for the hearing pathway. Note: not all terms will be used. Funneled vibrations push against the eardrum which moves the ___1_Ossicles___. The stapes pushes against the ___2__cochlear duct. Movement of tiny hairs inside the ____3_Organ of Corti___causes neurons to send impulses through a cranial nerve to the _Auditory Cortex___4__, located in the __5 Temporal____ lobe. 1: A. Auditory cortex. 4 2: B. Organ of Corti. 3 3: C. Stereocilia 4: D. Cochlear duct. 2 5: E. Ossicles. 1 F. Facial G. Temporal. 5 H. Parietal Other Incorrect Match Options: • C. Stereocilia • F.
