Document Summary
Reductionism: try studying complex item by studying its simpler form. Study what"s normal and working then figure out what isn"t working in the broken system. Things to think about during any discussion of experiments. Detect changes in the external and internal environment. Transmits this info to other cells for processing and storage. Instructs other cells how to respond to the changes detected. Central nervous system (cns) peripheral nervous system (pns) Human has 31 pairs of spiral nervous and 12 pairs of cranial nervous. Receive conduct and transmit signals over long distance and to precise target. Generally a single unbranched projection then branches at end. At the end, it signals to the next cell. Having multiple neurons connect by synapse to form circuits. Synapse= site of inter-cellular biochemical communication, i. e. sites at which one cell talks to the next cell in the pathway. To surround neurons and hold them in place. But problem: most drugs can"t pass thru it.
