THE NERVOUS SYSTEM NEURONS --a nerve cell that is specialized to transfer messages in the form of fast-moving electrical energy NEURON STRUCTURE • Cell body contains nucleus & organelles • Dendrites— extension of the cell that receives info from other cells • Axons can be almost 1m long • The tip is called the axon terminal SENSORY NEURON • collect Information • Receptors— specialized nerve endings • • Detect changes inside and outside the body Ex. Eye detects light MOTOR NEURONS • Send impulses from the brain and spinal cord to other systems • Muscles get impulses from Motor Neurons=musc les contract NERVES • Collection of axons bundled together with blood vessels and connective tissues • Everywhere in PNS SPINAL CORD
