Study Notes
Chapter 16 Learning Objectives
- Define receptor, sense organ, and transduction
- List four types of information obtained from sensory receptors and how the nervous system encodes each type
- Outline three ways to classify receptors and provide examples of each
- List several types of somatosensory receptors and provide an example of each
- Describe projection pathways for general senses
- Briefly explain pain mechanisms and spinal blocking of pain signals
- Describe the anatomy of a taste bud and the physiology of taste
- Describe the projection pathway for taste
- Describe the anatomy and physiology of smell perception
- Describe the projection pathway for smell
- Identify properties of sound waves (pitch and loudness)
- Describe the gross and microscopic anatomy of the ear
- Explain how the ear converts vibrations to nerve signals and discriminates between sound of different intensity and pitch
- Describe the anatomy of the vestibular system and how it helps the brain interpret body position and movements
- Briefly describe the pathways taken by auditory and vestibular signals to the brain
- Describe the anatomy of the eye and its accessory structures
- Describe the structure of the retina and its receptor cells
- Explain how the optical system of the eye creates an image on the retina, and how the retina converts this image to nerve impulses
