    • 11.1: Introduction to General and Special Sensory Tests
      This page presents learning objectives for a lab report on sensory perception, covering key concepts in vision and hearing, including the pupillary reflex and sound localization. It distinguishes between types of deafness, explains the vestibular apparatus's role in balance, and details how skin receptors transmit stimuli to nerves. The importance of sensory adaptation and the two-point touch threshold in various skin regions is highlighted.
    • 11.2: Sensory Tests on the Eye
      This page outlines various tests for evaluating visual perception and acuity, including identifying the blind spot, using the Snellen eye chart for visual acuity assessment, testing for astigmatism with an astigmatism chart, and observing the pupillary light reflex. Each test serves to measure different aspects of vision, such as myopia, hyperopia, and astigmatism, along with pupil responses.
    • 11.3: Sensory Tests on the Ears
      This page explains bone conduction's importance in hearing, allowing sound to bypass the middle ear. It details Rinne’s and Weber’s tests to differentiate between conduction and sensory deafness, including sound localization in Weber’s test and air versus bone conduction hearing in Rinne’s test. The page also provides steps for practically conducting both tests.
    • 11.4: General Sensory Tests
      This page details three sensory tests: the two-point threshold test evaluates touch receptor density by identifying the minimal distance for distinguishing two points on the skin; the temperature receptor adaptation test measures how quickly sensory receptors adapt to temperature changes; and the Romberg test investigates balance reliance on proprioceptors and visual input by assessing body movements with eyes open and closed. Results from these tests are to be carefully recorded.
    • 11.5: Results of Sensory Tests
      This page discusses sensory tests for vision, hearing, and equilibrium, detailing the Blind Spot Test, Snellen Eye Chart, Astigmatism Chart, Pupillary Reflex Test, Rinne's and Weber's Hearing Tests, Two-Point Threshold Test, Temperature Adaptation Test, and the Romberg Test. Students are tasked with documenting their findings and responding to questions about sensitivity, pupil reactions, types of hearing loss, and balance challenges experienced with closed eyes.
