2 kinds of Autonomic Nervous System

– Controls unconscious activities

restores the body to normal or relaxed mode

– “rest and digest”

The — is made up of peripheral nerves that connect the CNS to the rest of the body.

-controls involuntary responses

Divisions:

– Decreases heart rate, bronchiole dilation, blood glucose, blood to skeletal muscle

– Cranial & spinal nerves connecting CNS to HSIG heart, stomach, intestines, glands

-helps the body conserve E;

controls voluntary movements

-responsible for the actions that a person can control

Ex. Rest ; digest

– Cranial & spinal nerves connecting CNS to skin & skeletal muscles

Rod of tissue that runs down and back to the brain

Made up of cranial and spinal nerves

-carry info into and out of the BRAIN STEM

– “fight or flight"

– Oversees conscious activities

SPINAL CORD Protected by the spinal column and with

– Increases digestion, pupil size, urinary output

Ex. Inc heart rate and breathing, sweating

– Increases heart rate, bronchiole dilation, blood glucose, blood to skeletal muscle

- prepares the body for action and stress; fight or flight

– Decreases digestion, pupil size, urinary output

These neurons can regenerate if damaged.

Connects the CNS to the ORGANS and limbs

Ex of AUTONOMIC

-carry motor and sensory signals

PNS • — pairs of spinal nerves • — pairs of cranial nerves
