Term
what do spinal nerves control?
Definition
various bodily activities that are executed with little conscious effort or knowledge -- they transmit motor information from the CNS to the muscles, and carry sensory information from the peripheral receptors to the CNS

Definition
PNS
Term
what does the autonomic nervous system do?
Definition
controls and regulated the internal environment of our bodies
Term
