| Question | Answer |
|---|---|
| Two parts of the Nervous system | central peripheral |
| 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 |
