Document Summary
Vision, taste, smell, equilibrium, and hearing, complex organs contain large numbers of individual sensory receptor cells: vision, visual acuity - myopia (nearsighted) hyperopia (farsighted) Snellen chart determine degree of detail the eye can distinguish (cover one eye). Last line that can be read represents the approximate visual acuity for that eye. (20 feet: astigmatism defective curvature(causes blurring) some light rays not focused, spread out. Astigmatism chart normal all bars are sharp and evenly dark. Abnormal see some lines thick and dark while others are lighter and blurred. (10 feet: colour vision deficiency of receptor potentials (cones converting red/green/blue) Ichikawa colour vision test coloured plates (red-green blind), 3 seconds, says number, 8/10 right, normal (plates 5 to. 14), 3 > more responses = (plates 15-19) to determine type of blind. (30 inches) Sounds waves can be transmitted through air conduction and through bone conduction (mastoid). Ring through bone, then: rinne"s test normal is better hearing via air conduction than bone conduction.
