Physiology 2130 Lecture Notes - Ear Canal, Cone Cell, Sensory Neuron
Document Summary
Objectives: by the end of this section, you should be able to: Define a sensory receptor and its adequate stimulus. List the receptors responsible for touch, vibration, temperature, pain, and proprioception (limb position and movement). Name the two major ascending sensory pathways and describe their anatomy and the information they carry. List the somatotopic organization on the postcentral gyrus (somatosensory area), 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 the 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 action potentials. List four types of eye movements, describe when they occur, and describe their. Introduction changes to the sensory system changes rapidly. Section 7. 3 overall function. from air to fluid.
