Divisions of Nervous System Flashcards
what is the central nervous system made up of
brain and spinal cord
what are the 4 main lobes the brain consists of
frontal lobe
parietal lobe
temporal lobe
occipital lobe
what are the lobes functions
frontal lobe- associated with higher order functions
parietal lobe- sensory information
temporal lobe- processes auditory information
occipital lobe- processes visual information
what does the brain stem control
involuntary processes e.g breathing
role of the spinal cord
to transfer messages to and from brain
the peripheral nervous system consists of
somatic nervous system
autonomic nervous system
what is the role of the peripheral nervous system
to relay messages from the CNS to rest of body
role of somatic nervous system
to carry sensory information from the outside world to the brain and provide muscle responses via the motor pathways
what is the somatic nervous system made up of
sensory receptors that that carry information to brain and spinal cord
role of automatic nervous system
actions without conscious awareness that are regulated by the ANS
what are the two components of the automatic nervous system
sympathetic nervous system
parasympathetic nervous system
what is the sympathetic nervous system involved in
responses that prepare the body for flight or fight response
sympathetic nervous system pathway
impulses travel from the SNS to organs in the body to help us prepare for for action
increase more important things like heart rate and suppress digestion
role of the parasympathetic nervous system
to relax body and return us to our normal resting state
slows down heart rate, breathing rate
