Skip section 4 on the Endocrine System (pp 102-103)
Skip the specific neurotransmitters (Acetylcholine, GABA, Norepinephrine, Dopamine, Serotonin, Endorphin (pp 86-88)

Nervous System -
    Central Nervous System
            Brain
            Spinal Cord
    Peripheral Nervous System
            Somatic Nervous System (voluntary)
            Autonomic Nervous System (involuntary)
                    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

Neurons
    Cell Body
    Dendrites
    Axon
    Myelin Sheath
    Terminal Buttons
    Synapse
   
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

Action Potential
    All-or None Principle
