Question options: A medulla oblongata B pons C midbrainDiscuss the importance of performing the Pupillary Light Reflex test. Why is Pupillary Dark Reflex test necessary to perform in the clinic?The primary function of the lens of the eye is to: Question 7 options: Provide protection across the front of the eye Adjust the shape of the pupil Focus the visual image onto the optic disc Focus the visual image onto the fovea centralis
- Question:- Provide a general overview of how a sensory receptor or organ transmits information to the central nervous system. Include a discussion of the components of this system, e.g., axons, dendrites, cell body, synapse, and how they operateRecall that the eye is composed of three layers or "tunics" — the fibrous, vascular, and nervous layers — which enclose two cavities that are separated from each other by the lens. Review the components of these three layers by matching each description with the appropriate letter in the figure below: 1. Fluid in the anterior portion of the eye that provides nutrients to the lens and cornea 2. The "whites" of the eye 3. Area of the retina that lacks photoreceptors 4. Contains smooth muscle that controls the shape of the lens 5. Nutritive (nourishing) layer of the eye 6. Layer containing rods and cones 7. Gel-like substance that helps support the eyeball 8. Pigmented smooth muscles that control pupil size 9. Most anterior component of the fibrous layer — your "window to the world" 10. Structure that changes shape to bend light toward rods and conesThen, analyze the following hypothetical situation: Cassey Madrid is a medical assistant at a medical office. He is testing visual acuity in patients for the first time and feels nervous about it. However, Cassey remembered when he did it in his clinical procedures class, so he takes a deep breath and calls the patient, Mr. Saleto. After identifying the patient and welcoming him in the room, Cassey explains the procedure to Mr. Saleto. What should be the distance between Mr. Saleto and the Snellen chart? What instructions can Casey give to Mr. Saleto if he uses glasses? By using the Snellen chart, is Cassey testing distance or near visual acuity? What does it mean if the result of the test is 20/60? What are some nonverbal cues that may indicate that the patient is having difficulty reading the line to which Cassey is pointing?
