  1. What are the five functions of the nervous system
    homeostasis, integration, mental activity, sensory input, control of skeletal muscles
  2. What is the basic unit of a nervous cell
  3. What is an afferent neuron
    it is a neuron that takes information from the environment and takes it into the central nervous system
  4. what is an efferent neuron
    a neuron that takes inforation fro he central nervous syste and takes it to the environent
  5. What are motor neurons
    they are neurons that control movement
  6. what are the sensory neurons
    they are the neuron that control the 5 senses
  7. WHat are the two nervous systes
    central nervous and paripheral nervous
  8. what makes up the centrl nervous syste
    the brain and spinal cord
  9. what makes up the paripheral nervous system

  10. What are the three types of neurons
    multipolar;bipolar; unipolar
  11. what makes each type of neuron that kind of neuron
    • multipolar-when a neuron has many dendrite and one axon
    • bipolar-a neuron having one axon and one dendrite
    • unipolar-had one projection usually an axon
  12. what is the name of the litle gap between the the dendrites
  13. what enables the message to jump across the cynapse to the oher neuron
  14. What is a nissl body
    a large consintration of rough er.. mostly inly in neurons
  15. How many hemispheres are the brain divided into
    2; left and right
  16. what is the function of the corpus colosum

  17. How many lobes is in the human brain
  18. what are the four lobes of the brain
    frontal, pariteal, temperal, occipital
  19. what are the four regions of the brain
    cerebellum, cerebrum, brain stem and the dienlephalm
  20. what are the three parts of the dienlephalm
    epithalamus, thalimus, hypdthalimus
  21. which lobe controls the volunary motor functions, modivation, aggression, mood, and smell reception
    frontal lobe
  22. whichlobe controls reception, evaluation of dendory skills, touch, pain, temperature, balance, and taste
    parietal lobe
  23. whichlobe controls reception and integration of visual concepts
    occipital lobe
  24. which lobe controls ofactory sinsation(smell) hearing, and memory
    temporal lobe
  25. What three protections does the human body have to protect the bran and spinal cord
    menengies, skull, and cerebrospinal fluid
  26. what are the three parts to the menengies
    dura mater, arachnoid mater, and the pia mater
  27. whar are three parts o fthe brain stem
    medulla oblongata, pons mid brain
  28. white matter
    white in appearance; myelinates fibers of neurns(axons)
  29. grey matter
    composed of redish-grey dendrite fibers and amd nervoual bodies
  30. where is memory stored
    cerebral cortex
  31. what are brain waves measured by
  32. what are the four types of brain waves
    Alpah, theta, beta, delta
  33. when is the brain transmitting alpha waves
    in the 1st stage of sleep
  34. when is beta waves trasmitted
    when awake
  35. when isthe brain transmitting thea waves
    in the second stage of sleep
  36. when is the delta waves transmitted
    in the 3ed stage of sleep
  37. what stage of sleep is when R,E.M and dreams take place
    the fourth and last stage
  38. how are the vertebrae identified
    the region and the nUMBER
  39. How many cranial nerves are there
    12 pairs
  40. how many spinal nerves are there
    31 pairs
  41. what do the cerviacal spinal nerves control
    arms, neck, and hands
  42. what does the theracic spinal nerves do
    chest, abdoman, and arms
  43. Lumbar spinal nerves control
    legs and thighs
  44. sacral nerves control
    legs toes and groin
  45. why does the brain have sulci and gyri
    to have more surface area for chemical reactions
  46. what side of the brain is invovlved with problem solving, critical thinking, math, writing, and language
    left brain
  47. which side of the brain controls creativity, art, music, and space relation
    right brain
  48. what are the two types of brain matter
    white and grey
