processes, interprets, stores information; issues orders to muscles, glands, and organs
central nervous system
transmits information to and from the central nervous system
peripheral nervous system
bridge between brain and peripheral nerves
spinal cord
controls skeletal muscles
somatic nervous system
regulates glands, blood vessels, internal organs
autonomic nervous system
mobilizes body for action and energy output
sympathetic nervous system
conserves energy and maintains a quiet, at rest state
parasympathetic nervous system

Many functions
Relays information to/from cerebral cortex
Role in sleep/wake cycles, consciousness
thalamus
Many functions: hunger, thirst, temperature, sleep,
Regulating ANS
Hormone release
hypothalamus
allows left and right hemispheres to communicate
corpus callosum
plays a central role in states of consciousness and levels of arousal and has fibers that run vertical along the parts of the brain stem
reticular formation
the brain stem includes the:
midbrain, pons, medulla
Respiration Cough/gag reflex Pupillary response Swallowing Information relay between brain and spinal cord Unconscious motor movement
brain stem functions
Unconscious motor system that operates on a subcortical level
basal ganglia
“Little Brain”
Coordination, precision, balance at unconscious level
Speech fluidity
May also have a role in attention, memory, perception, social skills
cerebellum
OLD part of brain, raw emotion
Emotion, memory, behavior, smell
limbic system
ROLE in DECISION MAKING
Cingulate gyrus
FEAR, ANXIETY, ANGER, social cues, empathy
