Show Answers:

  1. respiration
    • power source for speech
    • breathing is typically involuntary
    • respiration for speech differs from respiration for breathing
    • many structures involved in breathing
  2. Heshal's gyrus
    connects broca's wernike's
  3. 5 organizational principles of the brain
    • interconnectedness  
    • hierarchy      
    • specialization    
    • plasticity    
    • critical period
  4. interconnectedness
    • has to the do with the fact that the brain is interconnected    
    • both hemispheres interact
  5. hiearchy
    • the central nervous system is hierarchical  
    • ex. when you put your hand on a hot stove, you know that you should take your hand off
    • levels of where stuff happens
  6. specialization
    • the two hemispheres are specialized to some degree (very important in certain functions)
    • language- left side; temporal parietal
  7. plasticity
    • brain's ability to change    
    • organize and modify functions      
    • brain should always be changing; always learning and growing
  8. critical period
    there is a period in which it is easier for you to learn language than others
  9. frontal lobe
    executive function (overall planning of what we do); personality; controlling speech
  10. broca's area (left frontal)
    fine motor coordination of speech; output of speech
  11. parietal
    on posterior; responsible for perceiving and integrating information; a lot of speech goes on here; math capabilities happen here
  12. central sulcus
    area in between the frontal and central lobe
  13. auditory cortex
    temporal processing and pitch processing; on the right side melody; on the left side the temporal
  14. right side of the temporal lobe
    wernike's lobe (language comprehension)
  15. occipital lobe
    visual information; understanding what you see
  16. brain controls _____ side of the body
    • opposite
    • ex. if you get in an accident and the left side of brain, you may get paralysis on the right side
  17. cerebrum
    that's where we do our thinking and planning problem solving
  18. cerebellum
    • has to do with balance and motor movement
    • also with some higher motor functions
  19. brain stem
    • at the top of the spinal cord (beneath the brain)    
    • carries a lot of nerve tracks    
    • communicates a lot of things to the brain
    • auditory and visual reflexes are controlled
    • associated with metabolism and arousal (what keeps us awake)
  20. brain
    commander and chief and mediator of the whole body
  21. vassals
    • cardiac: regulates heart          
    • baso motor center: controls blood vessels
    • respiratory: breathing
  22. speech and language are ____ functions
  23. central nervous system
    • brain 
    • spinal cord
  24. peripheral nervous system
    • has to do a lot with writing
    • 12 pairs of cranial nerves (these carry information to and from the brain and the spine and the rest of the body)    
    • parts of these nerves are sensory (what can you sense) which means they take information to the brain      
    • parts of these nerves are motor which means they carry information from the brain to parts of the body telling it what to do
  25. neurons
    • made up of a cell body with two extensions
    • dendrites that go into the cell body are called afferent          
    • axons are efferent
  26. Nervous system is made up of highly specialized cells called...
  27. synapse
    space where two neurons meet
  28. neurotransmitters
    chemicals that help neurons jump that synaptic cleft (from the axon on one to dendrite on another)
  29. the growth of the _____ isn't complete until late childhood
  30. what is the loss of myelin?
    multiple sclerosis
  31. pharynx (throat)
    • nasopharynx (level with nose)  
    • laryngopharynx (just above the larynx); sound source
  32. phonation
    • pharynx (throat)    
    • larynx
    • vocal fold vibration
    • trachea (tube that goes to your lungs)
  33. phonotory system
    manipulate air flow to create highly precise speech sounds
  34. maxilla
    upper jaw
  35. mandible
    lower jaw
  36. hearing
    • sound wave
    • mechanical energy
    • hydraulic energy
    • electrical energy to brain
  37. eustachian tube
    ventilates the middle ear
  38. dysphagia
    ineffeicient or unsafe swallowing
