central nervous system includes | brain & spinal cord |
peripheral nervous system includes | 12 prs cranial nerves 31 prs spinal nerves all their branches |
peripheral nervous system carries sensory messages: | TO the CNS |
cerebral cortex | cerebrum's outer layer of nerve cell bodies: also called gray matter |
cerebral cortex is the center for | humans' highest functions governing thought memory reasoning sensation voluntary movement |
Each half of the cerebrum is a | hemisphere |
Each hemisphere is divided into four lobes: | frontal parietal temporal occipital |
In addition to the cerebral cortex, the CNS has other vital coponents: | thalamus hypothalamus cerebellum midbrain and pons medulla spinal cord |
Frontal lobe fx | personality behavior emotion intellectual fxs |
Broca's area of cerebral cortex | motor speech |
precentral gyrus of cerebral cortex | primary motor area |
postcentral gyrus of cerebral cortex | primary sensory area |
parietal lobe fx | sensation |
Wernicke's area fx | speech comprehension |
occipital lobe fx | visual reception |
cerebellum | motor coordination equilibrium balance |
temporal lobe fx | hearing taste smell |
