Document Summary

Module 7 - sensory systems: y the body has several sensory systems that allow it to detect external changes rapidly. Transduction of environmental information: is how information from the external environment is turned into language the brain understands - action potentials. Includes: y touch y pressure y vibration y propioception (muscle sense) y y this stimuli will stretch sensory receptors in the skin and open ion channels causing a. Sound depolarization of the sensory neuron producing an ap. Includes: y taste y pain y odours y y y. Like a sour taste on the tongue or an odour in the nose, binds with a receptor, causing depolarization and then an ap. Light energy is absorbed by photoreceptors of the eye (rods and cones in the retina) and eventually produces aps.
