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
