Document Summary

Define a sensory receptor and its adequate stimulus. List receptors responsible for touch, vibration, temperature, pain, and proprioception. Name the two major ascending sensory pathways and describe their anatomy and the information they carry. List the somatotopic organization on the postcentral gyrus, going from medial to lateral on the cortex. Draw and label a picture of the visual system and the eye. List the cell types in retina and draw a diagram of their anatomical arrangement. List the functional characteristics of the rod and cone systems. Draw a flow diagram of the sequence of steps in the retina by which light is transduced to ap. List 4 types of eye movements, describe when they occur, and describe their overall function. Draw a simple diagram of the auditory system. List three ways in which the outer and middle ear act to transmit pressure waves from air to fluid. Describe how different frequencies of sound are transduced into ap.
