  1. Anatomy and Physiology for Emergency Care Chapter 10 Sensory Functions

  2. Objectives • Distinguish between the general senses and the special senses • Identify the receptors for the general senses, and describe how they function • Describe the receptors and processes involved in the sense of smell • Discuss the receptors and processes involved in the sense of taste

  3. Objectives • Identify the parts of the eye and their functions • Explain how we are able to see objects and distinguish colors • Discuss how the central nervous system processes information related to vision • Discuss the receptors and processes involved in the sense of equilibrium

  4. Objectives • Describe the parts of the ear and their roles in the process of hearing • Describe the effects of aging on olfaction, tasting, vision, and hearing

  5. General Senses • Pain • Temperature • Touch, Pressure, and Position • Tactile receptors • Baroreceptors • Proprioceptors
