The flashcards below were created by user amills1 on FreezingBlue Flashcards. What would you like to do?


  1. What is a ganglia
    grouping of neuron cell bodies outside the CNS
  2. What is absolute and relative refractory period
    • Absolute is when the membrane is depolarized and unable to create another AP
    • Relative is when hyperpolarized when a stronger than normal stimulus would be required to produce another AP
  3. What structures does the mid brain contain
    • Connects pons to diencephalon
    • contains ascending and descending tracts
    • contains oculomotor and trochlear CNs
    • contains relay stations for visual and auditory reflexes
    • contains subsstantia nigra
  4. purpose of substantia nigra
    • large motor nucleus connecting with the basal ganglia and cortex
    • important in motor control and muscle tone
  5. location and importance of pons
    • connects medulla oblongata to midbrain
    • allows passage of ascending and descending tracts
    • contains nuclei for trigeminal, abducens, facial, and vestibulocochlear CNs and nuclei for regulation for respiration
  6. location and importance of medulla oblongata
    • connects SC with pons
    • contains¬†all ascending and descending tracts
    • contains glossopharyngeal, vagus, spinal accessory, and hypoglossal CN nuclei
    • contains important centers for vital sign fxning: cardiac, respiratory, vasomotor centers, and reticular formation (maintenance of consciousness and arousal)
  7. what is the diencephalon composed of?
    thalamus anbd hypothalamus
  8. importance of thalamus
    • group of nuclei deep within the cerebrum
    • receives all sensory stimuli except smell
    • interprets crude sensory info
  9. importance of hypothalamus
    • primary role is homeostasis
    • regulates body temp, sugar and fat metabolism and water balance
    • primitive drives for eating, sexual behavior, rage, aggression, emotion, thirst, hunger, and sleep/wake cycles
  10. Fxns of the cerebellum
    • equilibrium
    • regulation of muscle tone
    • maintenance of posture and voluntary movements
    • coordinates smooth voluntary movements
    • motor learning
    • sequencing of movements
  11. How many total spine nerve pairs and how many per level
    • 30
    • 8C
    • 12T
    • 5L
    • 5S
    • A few coccygeal
  12. What segments make of the brachial plexus? Lumbosacral?
    • C5-T1
    • T12-S2
  13. UE synergy pattern of spasticity
    • retraction, downward rotation
    • adduction, IR, depression
    • Elbow flex
    • Pronation
    • Wrist flex and adduction
    • Hand finger flexion, clenched fist, thumb adducted inside
  14. LE spasticity pattern
    • Pelvis hiked
    • hip add, IR, /
    • knee /
    • ankle PF, inver, toes claw (MPT /, rest flexed)
    • toes curl
  15. What is glasgow scale for and general scoring of it
    • consciousness
    • 3-15, the lower the worse TBI class
  16. What is anosognosia
    severe denial, neglect, or lack of awareness of dysfxn or a condition
  17. Apraxia
    inability to perform purposeful movements when there is no loss of sensation, strg, coordination, or compreshension
  18. Cerebellar lesions result in hyper or hypone tone? LMNL result in? Spinal Shock?
    All flaccidity
  19. Modified Ashworth scale measures what?
    • Tone levels
    • 0-4 range, 0 being no increase in tone
  20. Nerve root level for DTRs c5-6, c7-8,
    • C5-6= biceps and brachioradialis
    • C7-8= triceps
  21. Nerve root level DTRs for L5-S3, L2-L4, S1-S2
    • L5-S3= h/s
    • L2-4= quads
    • S1-2= achilles
  22. What is Ramiste's phenomenon
    Resisted hip abd/add of uninvolved limb causes same reaction in involved limb
  23. What is homolateral limb synkinesis
    flexing involved UE causes flexion of involved LE
  24. What is dysdiadochokinesia
    difficulty performing rapid alternating movements
  25. What is chorea
    involuntary relatively quick twitches or "dancing" movements
  26. What is athetosis
    involuntary, slow, irregular, twisting, sinuous movements
