Nervous System
 Neurons- cells that transfer information throughout
the body
 Chemical
 Electrical
 Brain- large group of neurons
Neuron Anatomy & Physiology
 Cell highly specialized- perfect for receiving and sending
signals
 Cell body
 Dendrites
 Axon
 Synapse
Nerve Impulse
Nerve Impulse
Support System- Glial cells
 Nourish neurons
 Regulate extracellular fluid
 Protective covering (myelin)
Information Processing
 3 stages: Sensory input, integration, motor output
 Sensory neurons
 Interneurons
 Motor neurons
Organization
 Central Nervous System- consists of neurons that deal with
integration
 Spinal cord and brain!
 Peripheral Nervous System- neurons that carry information into
and out of the CNS
