    Study Notes

    Central Nervous System (CNS)

    • Consists of the brain and spinal cord

    Peripheral Nervous System (PNS)

    • Consists of all nervous tissues outside the CNS, including nerves, ganglia, and sensory receptors
    • Consists of nervous tissue outside the CNS
    • Acts as a messenger, delivering CNS decisions to the rest of the body

    Nerve Pairs

    • Cranial nerves have 21 pairs
    • Spinal nerves have 13 pairs

    Control Systems

    • Two major control systems: sensory and motor

    Nerve Function

    • Carries information to the CNS (sensory function)
    • Carries information to the body from the CNS (motor function)
    • Processes information within the CNS (integration function)

    Neuron Structure

    • Typical neuron structure: many dendrites, 1 axon
    • Another type of neuron structure: 1 dendrite, 1 axon
