Neurons
Nerve cell
basic structural unit of the nervous system
Parts of a neuron
Cell Body
contains the nucleus
Dendrites
nerve filters that carry impulses toward the body
Axon
a single nerve filter that carries impulses away from the body
Synapse
impulse must jump to carry message being transmitted
Neurotransmitters
Special chemical messengers that allows impulses to jump to next neuron
Myelin Sheath
fat covering on axon that insulates and increases rate of transmission
