Nervous System

Structure that responds to a stimulus

Carries impulses from receptors to brain/spinal cord

Carries impules from brain/spinal cord to effectors

Connect the sensory to the motor neurons

Depolarization and repolarization of a neuron membrane

The minimum level of stimulus needed to start an impulse

Chemical released at the axon terminals carries impluses

Extension that recives message and carries impulse toward cell body

Contains the nucleus and most cytoplasm of neuron

Extension that carries impulse away from cell body

Sheath that surrounds axon

Makes up myelin

Space between Schwann Cells

End of axon at synapse

Small gap between neurons
