Autonomic nervous system

• Consists of the brain and spinal cord.

• Division of the PNS that transmits action potentials from sensory organs to CNS.

• Efferent subdivision that transmits impulses from CNS to skeletal muscle.

• Consists of nerves, receptors, ganglia, and synapses outside the CNS.

• Efferent subdivision that transmits impulses from the CNS to smooth muscle, cardiac muscle and Glands.
