Nervous system

Cards (24)

  • 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
