Sympathetic Nervous System (Arousing)
Parasympathetic Nervous System (Calming)
Afferent Nerves - sensory nerves
- transports information from
the sensory system to the brain
Efferent Nerves - motor nerves
- transports information from
the brain to the muscles
Inter-neurons - transports information from one neuron to another neuron

Resting potential = -70 millivolts
Sodium channels open and Sodium ions enter the neuron
Electrical charge becomes positive
Potassium channel open and Potassium moves out of the neuron
Electrical charge becomes negative
