  1. Meninges
    • Dura Mater - outer
    • Arachnoid Mater
    • Pia Mater - Inner
  2. Frontal Lobe
    • Intellectual function & personalilty
    • voluntary movements, speech(expression)
  3. Parietal Lobe
    Sensory info is received
  4. Temporal Lobe
    • Sensory infor is interperted and memory is stored
    • hearing, language reception and understanding, memory
  5. Occipital Lobe
    Vision & processing or visual infor
  6. homunculus
    Representation of the body on the surface of the brain on the sensory and motor strips
  7. Cerebellum
    • Muscle coorination
    • tone
    • possure
    • equillibrium
  8. Basal Nuclei
    • Moto control and coordination
    • located in the midbrain
  9. Limbic System
    Nuclie and fibers at teh top of the brainstem responsible for emotional reactions and feelings
  10. Hyopthalamus
    • Controls body temp appetit sleep
    • Maintains homeostaiss
  11. Thalumus
    Relay station for sensory impulses
  12. Medulla
    control center ofr respiratory vasomotor & cardiovascualr function cough reflex, swallowing, vomitng
  13. Pons
    dundles of affernet/ efferent fibers
  14. Reticular Activiating System
    • Scattered neurons, governs degree of arousal or awarness
    • Puts people in a coma
  15. 4 main Branches of blood supply to the brain
    • Anterior Berebral Artery ACA
    • Middle Cereral Artery MCA Most common for CVA
    • Posterior Cerevral Artery PCA
    • Vertebrobasilar
  16. Ascending White Matter Tracts
    • Spinocerebellar
    • Spinothalamic
    • Dorsal Columns
  17. Descending White Matter Tracts
    • Corticospinal
    • Tectospinal
    • Reticulospinal
    • Rubrospinal
  18. What do the Dorsal Columns Detect
    Touch and pressures
  19. Anterior Apinothalamic Tract
    Light Touch
  20. Lateral Spinothalamic Tract
    Pain and Temp
  21. Anterior Spinocerebellar
    Position Sense
  22. Autonomic Nervous System
    • Sympathetic (fight or flight)
    • Parasympathetic
  23. Glasgow Coma Scale
    • Eye Opening
    • Motor Response
    • Verbal Response
  24. Coma
    Pt doesn't respond to painful or verbal stimulie body is flaccid
  25. Persistent Vegetavtive State
    • a continuing and unremitting clinicla condition of complete unawareess of the environment accompied by slepp wake scyles
    • will have partial or complete preservation of hypothalmus and branstem autonomic functions
  26. Locked in Syndrome
    • A paralytic condition, superficially resembling coma
    • Pt has no voluntary control over muscles but remains awake and alert. Usually the result of a brainstem lesion especiall the pons. In some Pt eye blinking is precerved and communicaiton wiht the Pt becomes possible
  27. Brain Death
    • Flat EEG
    • Cessation of brain funcion
    • Absent Brainstem refexes absence of spontaneous respiration
  28. Decorticate Posture
    • Mid brain injury
    • Arms in flexion
  29. Decerebrate Posure
    • Worse of the two
    • Arms in extension
  30. Upper Motor Neuron Lesion
    • Lesion above the AHC
    • Loss of Voluntary control
    • Hyeractive reflexes
    • Increased tone sensory loss
    • Involuntary motions
    • EX: CVA tumor Parkinsonims, CP
  31. Lower Motor Neuron Lesion
    • Lesion at or below AHC
    • Decreased or absent reflexes
    • Atrophy
    • Fasciculation
    • May affect Sensation
    • EX: trauma, infections, GB, MD, Spina Bifida
  32. Tremors
    • Involuntary, pruposless, rhymatical movement
    • can be resting or intension
  33. Chorea

  35. Homoynous Hemianopsia
    One half of each visual field is lost
  36. Expressive Aphsia
    • Thoughts are in the head but can not get them out written or verbal
    • Broca's Area posterior Frontal Lobe
  37. Receptive Aphasia
