Document Summary
3. 1 cells of the nervous system: the first anatomists to study brain cells developed methods of highlighting individual cells in nervous system tissue, to make the tissue firm, they soaked it in formaldehyde. The red gene is obtained from coral, and the blue and green genes are obtained from jellyfish: the mice also received a bacterial gene called cre. Neurons: the basis of information processing: as the information-processing units of the nervous system, neurons acquire information, interpret it, and pass the information along to other neurons that initiate a behavior. In engaging in this activity, neurons also encode memories and produce our thoughts and emotions. It carries information from the cerebellum to the rest of the brain and spinal cord. Motor neuron: motor neuron: cell that carries efferent information from the brain and spinal cord to make muscles contract, motor neurons have extensive dendritic networks, large cell bodies, and long axons that connect to muscles.
