cerebral cortex areas
Show Answers:

  1. Primary sensory area (Post-central gyrus) Parietal Lobe
    • Where we first become consciously aware of a sensation. body region being stimulated is identified via spatial discrimination.
  2. Somatosensory association cortex (Parietal Lobe)
    Produces an understanding of sensory inputs. Would not be able to recognize objects without looking at them
  3. Somatosensory homunculus
    shows the relationship of body part sensitivity relative to what its size would be
  4. Primary visual cortex (Occipital lobe)
    Produces visual sensations from neural impulses originating from the eye
  5. Visual association area (occipital lobe)
    uses past experiences to make sense of what is presently seen
  6. Primary auditory area (temporal lobe)
    pitch, loudness, and location of soundis interpreted
  7. Auditory association area (temporal lobe)
    permits what we “hear.” past sounds are also stored here
  8. Primary olfactory cortex (temporal lobe)
    Smell impulses are sent here
  9. Olfactory association cortex (temporal lobe)
    conscious awareness of odors/interpretation
  10. Primary gustatory area (temporal lobe)
    Interprets taste
  11. Wernicke’s area (temporal lobe)
    arranges vocabulary into meaningful speech
  12. Premotor cortex (frontal lobe)
    “Executive decision area” Decides whether or not to do something, if so compiles the plan for muscle contractions
  13. Prefrontal cortex (frontal lobe)
    Controls group muscle contraction
  14. Primary motor cortex (pre-central gyrus)
    Allow us to control voluntary movements of our skeletal muscles
  15. Broca’s area (frontal lobe)
    Controls motor speech function. Coordinates lips, tongue, and cheeks for speech
