Document Summary

Transducion: changing energy from one form to another, nervous system is an electrical system. Diferent objects relect colours diferently: proximal simulaion. Light being shone onto the back of our eye (reina) Mechanical energy: molecules cause movement in ear and neurons are acivated. Interpretaion: what does the patern of electrical signals mean, can add informaion to ill in missing parts (necker cube) Overview: the neuron and its parts: nervous system take informaion from one place to another (communicaion system, neuron. Size of axon determines speed electric charge travels: thicker axons faster, narrow axons slower. In invertebrates only the axon size determines how quickly informaion travels. Informaion sends quicker when there is myelin on the axon. Myelin forms from head to toes, and center of the body to the periphery. How is informaion transferred inside a single neuron (pre-synapic transmission) Element is the pure form of a substance. Ion charged paricles (steals electrons from another element)
