Be able to identify 5-15 on the eye models. 1. Conjunctiva 2. Photoreceptors a. Cones b. Rods 3. Aqueous humor 4. Vitreous body 5. Lacrimal gland 6. Lacrimal sac 7. Three layers of eye a. Scleroid coat (outer layer) b. Choroid coat (middle layer) c. Retina (innermost layer) 1 C. 8. Optic nerve 9. Optic disk (“blind spot”) 10. Fovea centralis a. Macula lutea (“yellow spot”) b. Macular degeneration 11. Lens 12. Iris 13. Pupil 14. Cornea 15. Muscles – only be able to find these on the eye models a. Superior rectus (rectus means straight) b. Inferior rectus c. Lateral rectus d. Medial rectus e. Superior oblique f. Inferior oblique Be able to identify the following structures on the cow eye. Exercise 34, Procedure B 1. Optic nerve (stump) 2. Three layers of the eye (sclera, choroid, retina) 2 D. 3. 4. 5. 6. 7. 8. 9. Optic disk Lens Vitreous body Iris Pupil Cornea Tapetum lucidium (fibrosum) 10. 11. Ciliary body Suspensory ligament TESTS – Perform the following tests and understand the underlying principles. See Exercise 35 1. Blind Spot 2. Near Point of Accommodation and Presbyopia 3. Visual Acuity using the Snellen Eye Chart 4. Test for Astigmatism 5. Test for Color Blindness using Ishihara Plates 6. Photopupillary Reflexes 3 E. II. 7. Accomodation Pupillary Reflex 8. Convergence Reflex Review your work from last semester about the following diseases and what causes each: 1. Near-sightedness 2. Far-sightedness 3. Astigmatism 4. Cataracts 5. Glaucoma The Ear - Hearing and Equilibrium Hearing - Exercise 32 A. You are responsible for the “Sense of Hearing” section of the textbook. B. Find the DESCRIPTIONS AND LOCATIONS of the following structures on the ear model and write them out below. Be able to identify them on the ear models. 1. Auricle 2. External auditory meatus 3. Tympanic membrane 4. Three bones of middle ear (ossicles) a. Malleus b. Incus c. Stapes 4 5. Oval window 6. Eustachian (auditory) tube 7. Semicircular canals 8. Vestibule 9. Cochlea 10. Vestibulocochlear (Auditory) nerve C. Label the structures on Figure 32.1, 32.2, and the upper portion of 32.3. Use your lecture book to assist you. D. Perform the Tuning Fork Methods (Rinne and Weber Tests) E. Fill in Part A, Assessments, Exercise 32 Equilibrium – Exercise 33 A. You are responsible for the “Sense of Equilibrium” material from the lecture text B. Review your work from last semester about the following diseases and their cause 1. Nystagmus 2. Vertigo C. Three Factors that Affect Equilibrium (balance) 1. Vision – do the “Vision and Equilibrium Test” 2. Equilibrium apparatus of the inner ear (semicircular canals and vestibule) do the “Romberg Test” 3. Proprioceptors – do the “Barany Test” 5
