divisions of the nervous system Flashcards
what is part of the central nervous system
All the neurons within the brain and
spinal cord.
All the parts of the nervous system within the spinal column and skull
what is part of the peripheral nervous system
All the parts of the nervous system that are outside the brain and spinal cord.
what do the spinal cord and brain do
main controllers of neural activity and behaviour
the nervous system is made up of which 2 subsystems
the central nervous system and the peripheral nervous system
what are the 2 divisions of the peripheral nervous system
somatic and autonomic nervous system
what does the somatic nervous system contorl
voluntary muscle movement of skeletal muscle
what does the autonomic nervous system control
involuntary activity of non skeletal muscle and internal body systems
self regulating
what are the divisions of the autonomic nervous system
sympathetic and parasympathetic nervous system
the sympathetic nervous system is which one
the fight or flight response
the parasympathetic nervous system is whihc one
the rest and digest one
what are the 2 divisions of the peripheral nervous system (not somatic and autonomic)
sensory (afferent) division and motor (efferent) division
what does the sensory afferent division do
sends sensory input to the cns
what does the motor efferent division do
sends motor signals from the cns to muscles and glands
what are the 4 lobes of the cerebrum
frontal, parietal, occipital, termporal
what is the frontal lobe involved in
thought, speech production, impulse control, and working memory
what does the parietal lobe process
sensory information eg touch, pain temperature
what does the occipital lobe process
visual information
what does the temporal lobe involved with
hearing and language comprehension
the brain stem is responsible for regulating…… which are essential for….. eg
regulating autonomic function which are essential for life eg breathing, heartbeat, swallowing
the brain stem includes which strucutre
medulla oblongata
where is the cerebellum located
sits beneath the back of the cerebrum
what is the cerebellum involved in controlling
motor skills balance and coordinating muscles
the brain stem allows impulses to pass between the
brain and the spinal cord
where is the diencephalon located
on top of the brain stem
