  1. Components of the Cerebral Cortex
    • Frontal lobe- personality, Bx, emotion, intellect
    • Parietal lobes- sensation
    • Occipital lobe- visual receptor center
    • Temporal lobes- auditory receptor center
  2. Function of Basal Ganglia
    automatic associated movements (extrapyramidal) i.e. alternating legs while walking
  3. Function of the Thalamus
    relay station. Sensory pathways of spinal cord and brainstem form synapses on way to cerebral cortex
  4. Function of the Hypothalamus
    control center. Vital function control (Temp, HR, BP), sleep, regulates ant. + post. pituitary gland, ANS coordinator, emotional status
  5. Function of the Cerebellum
    the “automatic pilot” . motor coordination of voluntary movements, equilibrium (posture), muscle tone
  6. General Function of the Spinal Cord
    “Highway” for descending and ascending fiber tracts connecting brain to spinal nerves; mediates reflexes
  7. What are the 2 pathways of the CNS and each of their routes?
    • 1. Sensory pathways: (afferent)
    • a. Spinothalamic tract: pain, temp, light touch
    • b. Posterior (dorsal) column: position, vibration, fine touch
    • 2. Motor pathways (efferent)
    • a. Corticospinal or pyramidal tract: mediate skilled, discrete, purposeful movements
    • b. Extrapyramidal tracts: maintain muscle tone and control body movements
    • c. Cerebellar system: coordinates movement maintains equilibrium and posture

    • [tip: confusing because they sound the SAME.
    • Sensory = Afferent. Motor = Efferent ]
  8. 4 Types of Reflexes
    • 1. Deep Tendon Reflexes (ex. knee jerk)
    • 2. Superficial (abdominal reflex)
    • 3. Visceral (pupil response to light)
    • 4. Pathologic (Babinski’s in adult)
  9. Glasgow Coma Scale
    • defines LOC by numeric value.
    • 1. Best eye opening
    • 2. Best motor response
    • 3. Best verbal response
  10. Cranial Nerve Assessments
    • I, II: smell, visual acuity
    • III, IV, VI: extraocular movements
    • V, VII: corneal reflex, facial movements
    • VIII: sound articulation (whisper test)
    • IX, X: cough, swallow, "ahh"
    • XI: neck and head movement
    • XII: tongue movement, articulation
  11. What is a dermatome?
    circumscribed skin area that is supplied mainly form one spinal cord segment thru a particular spinal nerve (they overlap on edges)
  12. Dysphagia vs. Dysphasia
    • DysphaGia- difficulty swallowing [G for Gut]
    • DysphaSia- difficulty speaking [S for Speech]
  13. Components of a Neuro Re-check
    • 1. LOC (x 4)
    • 2. Motor function (voluntary movement, hand grasp)
    • 3. Paupillary response (direct and consensual)
    • 4. Vital signs (temp pulse, RR, BP)
    • (5.) Glasgow Coma Scale
