  1. diencephalon
    • Thalamus
    • hypothalamus
  2. The 2 major arteries from the aortic arch?
    • Internal carotid arteries
    • Vertebral arteries
  3. Carotid arteries branch to supply most of the
    • Frontal, parietal, and temporal lobes
    • Basal ganglia
    • Part of the diencephalon
  4. Vertebral arteries join to form the basilar artery, which supply the
    • Middle and lower temporal lobes
    • Occipital lobes
    • Cerebellum
    • Brainstem
    • Part of the diencephalon
  5. Right and Left Carotid Arteries connect when they enter the brain
    • each sends out a small lateral branch that meets in the space between (Anterior Communicating Arteries)
    • carotids branch backwards to join with posterior cerebral arteries (Posterior Communicating Arteries)
    • *It attempts to protect the brain should major arteries coming through neck be blocked*
  6. Anterior Circulation- supplies the front, top & side portions of the cerebral hemispheres via the Internal Carotid Arteries and their branches
    Anterior Cerebral Arteries (ACA)
    Middle Cerebral Arteries (MCA)
  7. Posterior Circulation- supplies the brainstem, cerebellum, as well as the posterior and undersides of the cerebral hemispheres via the Vertebral Arteries and their branches
    • Basilar Arteries
    • Posterior Cerebral Arteries (PCA)
  8. Frontal lobe
    • Front-Higher mental function-concentration, planning, judgement, inhibition (self-conscious), emotional expression, creativity.
    • Middle (Cerebral cortex)-eye movement and orientation (motor function area)
    • Side (broca's area)-muscles of speech
    • Back (precentral gyrus) -Initiation of voluntary muscles (motor function area)
  9. Parietal lobe
    • front (post central gyrus)-sensation from muscles and skin (sensory area)
    • back-object recognition (wieght, temperature, texture) (somatosensory association area)
  10. Temporal
    • Front-Association area-short-term memory, emotion, equilibrium. (association area)
    • top rear-hearing (auditory area)
    • bottom rear-written and spoken language comprehension (wernicke's area)
  11. occipital lobe
    sight, image recognition, image perception (visual area)
  12. cerebellum
    coordination of movement, balance and equilibrium, posture. (motor functions)
  13. Deep around thalamus
    emotion
  14. bottom right and left temporal
    Olfactory
  15. Anterior Cerebral Artery CVA: (rare)
    • Paralysis and impaired sensation of LE more severe than UE on contralateral side
    • Loss of bowel and bladder control
    • Balance problems in sitting/standing
    • Memory deficits
    • Lack of spontaneity of emotions
    • Loss of communication
  16. Right-Sided CVA of MCA:
    • Weakness/paralysis/impaired coordination on left side of face, trunk, extremities
    • Impaired sensation on left side of body
    • Deficits in spatial and perceptual awareness, including dressing apraxia
    • Left neglect
    • Visual field cuts on left side of visual field
    • Impulsive behavior/ impaired judgment
    • Dysphagia related to   initiation/swallow
  17. Left –Sided CVA of MCA:
    • Weakness/paralysis/ and impaired coordination on right side of face/trunk/extremities
    • Impaired sensation on right side of body
    • Visual field cuts usually on right side of visual field
    • Dysphagia – swallow impairment – weakness related
    • Language deficits (aphasia and dysarthria)
    • Memory deficits for recent or past events
    • Analytical – very slow to process
  18. Vertebral /Basilar CVA:
    • Variety of visual disturbances incl. impaired ocular coordination
    • Impaired sensation and weakness/paralysis of extremities/face/tongue due to cranial nerves
    • Impaired ability to read/name objects
    • Vertigo/Ataxia
    • Memory impairments
  19. brainstem
    • Swallow
    •  Breath
    • Heartbeat 
    • Wakefulness
