Unformatted text preview: 1 Department of Biology BY 101 Human Senses 2 Topic Objectives 1. What are the five senses? To what type of stimulus does each respond? 2. What are the three primary structures of the auditory system? What is the primary function(s) of each? 3. Know the structures and functions of the outer ear 4. What are the components of the middle ear? What are their functions? 5. What is the primary structure of the inner ear? What is the internal composition of this structure? 6. What is the progression of sound (energy) waves through the inner ear? 7. Where is sound produced? Explain. 8. What part of the ear is involved with the sense of balance? Understand how each structure contributes to balance. 3 Topic Objectives 1. In addition to the structures in the ear, what other parts of the body are involved with the sense of balance? 2. What is the sense organ for the sense of touch? Where in the sense organ are the sensory neuron actually located? 3. What determines the sensitivity of the skin? What determines the ability of the skin to detect different types of sensations? 4. What is the sense organ for the olfactory system? Where are the sensory neurons located? What is the sensory stimulus? 5. Why is the olfactory system so unique when compared with the other four senses? 6. What is the sense organ for the sense of taste? Where are the sensory neurons actually located? What is the sensory stimulus for this sense? 7. What are the five taste sensations? 4 Topic Objectives 1. What is the relationship between the senses of smell and taste? 2. What are the sense organs for the sense of vision? What is so unique about the organs? 3. What part of the electromagnetic spectrum can human eyes detect? 4. What are the external structures, and what do they do? 5. Where are tear glands located, and what is their function? 6. Know the internal structures of the eye. How do they contribute to either the structure of the eye or the function of the eye? 7. What structure(s) controls the focusing of light on the retina? How is this focusing process controlled? 8. What are the two photosensitive neurons in the sense of vision? Where are they located? 5 Topic Objectives 1. Know how the rods and cones function? What is the difference in their chemistry? 2. What is the difference between vision and perception? 3. Understand the relationship between visual pathways and depth perception. 4. Understand the problem with each of the following visual abnormalities: Myopic vision, hyperopic vision, astigmatism, presbyopia, and cataracts 6 Peripheral Nervous System (PNS): Two Functional Divisions Sensory (afferent) division Sensory neurons carry impulses from all senses to the central nervous system Motor (efferent) division Transmits impulses from the central nervous system to effector organs 7 Human Senses Hearing Touch Smell Taste Vision Mechanical stimuli Chemical stimuli Electromagnetic stimuli 8 Hearing Auditory System...
