Show Answers:

  1. 3 main sections of frontal lobe and what they control
    • precentral gyrus: vol muscle activation
    • prefrontal cortex: emotions and judgments
    • broca's area: speech
  2. main area of parietal lobe
    postcentral gyrus: sensory, proprioception, pain, temp (contralat)
  3. temporal lobe - 3 main areas and what they do
    • primary auditory cortex: receives/processes auditory stim
    • associative auditory cortex: processes auditory stim
    • wernicke's area: language comprehension
  4. insula lobe does is where, asociated w what?
    • lateral sulcus
    • visceral functions
  5. limbic system deals with what
    instincts, emotions, feeding, aggression
  6. archicerebellum / glocculododular lobe -- does what
    • equilibrium
    • regulation of muscle tone
    • vestibulo-ocular reflex
  7. paleocerebellum / rostral cerebellum / spinocerebellum - for what?
    • proprioception
    • modifying muscle tone and synergistic actions of muscle
    • posture
    • voluntary movement control
  8. neocerebellum (pontocerebellum)
    • smooth coordination of vol mvmnts
    • ensures accurate force, direction
    • important for motor learning, sequencing mvmnts
  9. dorsal columns / medial lemniscal system -- do what?
    • ascending sensory pathway
    • convey sensations of proprioception, vibration, tactile discrim
  10. 2 parts of dorsal column / medial lemniscal system
    • fasciculus cuneatus (UE)
    • fasciculus gracilis (LE)
    • they cross in the medulla
    • they convey proprioception, vibration, tactile discrim
  11. spinothalamic tracts convey what?
    • pain and temp (lateral spinothalamic tract)
    • crude touch (ant spinothalamic tract)
  12. lat spinothalamic tract conveys what?
    pain and temp
  13. ant spinothalamic tract conveys what?
    crude touch
  14. spinocerebellar tracts convey what?
    proprioceptive info from muscle spindles, GTOs
  15. spinoreticular tracts convey what?
    deep and chronic pain
  16. corticospinal tracts are important for ...
    vol motor control
  17. vestibulospinal tracts are important for
    control of muscle tone, antigravity muscles, and postural reflexes
  18. rubrospinal tracts do what
    assist in motor function
  19. reticulospinal system is involved in what
    • modified transmission of sensation, esp pain
    • influences gamma motor neurons and spinal reflexes
  20. tectospinal tract does what
    assists in head turning responses to visual stim
  21. A nerve fibers are large, myelinated, fast conducting
    what do the alpha conduct
    proprioception, somatic motor
  22. A nerve fibers are large, myelinated, fast conducting
    what do the Beta conduct
    touch, pressure
  23. A nerve fibers are large, myelinated, fast conducting
    what do the gamma conduct
    motor to muscle spindles
  24. A nerve fibers are large, myelinated, fast conducting
    what do the delta conduct
    pain, temp, touch
  25. what are B fibers like
    • nerve fibers that are small, myelinated, slower than A
    • preganglionic autonomic
  26. C fibers?
    2 types
    • smallest
    • unmyelinated / slowest
    • dorsal root: pain, reflex
    • sympathetic: postganglionic sympathetics
  27. state of obtundation
    • pt can open eyes and look at PT but responds slowly and is confused
    • decreased alertness and interest in env
    • (more aroused than "stupor," less than "lethargy")
    • stupor - can be aroused from sleep only by painful stim
  28. unresponsive vigilance state
    what is it
    • vegetative
    • has sleep/wake cycles and normal bodily functions
    • can be aroused but is unaware / lacks cognitive responsiveness
  29. scoring on mini-mental state exam
    • 21-24: mild cog impairment
    • 16-20: mod impairment
    • <15 : severe impairment
    • (it's like the Rancho and Brunnstromm scales, where low is bad)
  30. apneustic breathing
    • abnormal resp marked by prolonged insp
    • accompanies damage to upper pons
  31. kernig's sign
    for what?
    • meningeal irritation
    • supine, bring knee to chest, then extend knee
    • pos: pain and tightness 2/2 spasm of hamstrings
  32. brudzinski's sign
    for what? 
    • meningeal irritation
    • supine, flex neck to chest
    • pos: this triggers flexion of hips and knees
