The nervous system is broken up into 2 parts; the
central
nervous
system
(
CNS
) and the
peripheral
nervous
system
(
PNS
)
The Central Nervous System (
CNS
) is broken up into the
brain
and
spinal
cord
The
spinal
cord
transfers messages between the
brain
and
body
The peripheral nervous system is broken down into the
autonomic
nervous system and the
somatic
nervous system
The autonomic nervous system carries out
homeostasis
keeping the
internal
conditions
of the body
constant
The
autonomic
nervous system is broken down into the
sympathetic
and
parasympathetic
divisions
the
sympathetic
division of the
autonomic
nervous system carries out
fight
or
flight
the
parasympathetic
division of the
autonomic
nervous system carries out
rest
and
digest
the
somatic
nervous system communicates
sense
organs
with
voluntary
muscles
6 main brain regions;
frontal
lobe,
parietal
lobe,
temporal
lobe,
occipital
lobe,
brain
stem
, and
cerebellum
The Frontal lobe controls
logic
and
thinking
the parietal lobe controls
spatial
navigation
the temporal lobe processes
auditory
information
the occipital lobe processes
visual
information
the brain stem controls
involuntary
functions
the cerebellum controls
coordination
both the
brain
stem
and
spinal
cord
control
involuntary
functions
EG brain stem controls
breathing
and the spinal cord controls the
reflex
arc
the brain allows for
conscious
awareness
while the spinal cord carries out simple
reflex
responses
the brain has
multiple
regions
that carry out many different
functions
while the spinal cord only has
one
main
function
the
somatic
and
autonomic
nervous system both respond to
external
stimuli
the
autonomic
nervous system consists of
two
subsections
while the
somatic
does not
the
somatic
nervous
system has both
sensory
and
motor
pathways while the
autonomic
only has
motor
pathways
the
autonomic
nervous
system controls
internal
organs while the
somatic
nervous
system controls
muscle
movement
The
endocrine
system
consists of a network of
glands
that secrete
hormones
into the
blood
stream
that work
slower
than
nerve
impulses
