Document Summary

Major divisions of the nervous system (i): central nervous system (cns) comprises the brain and the spinal cord, peripheral nervous system (pns) consists of everything outside the skull and spinal column. Major divisions of the nervous system (ii): afferent: going towards (approach, advance, efferent: going away (exit, escape, somatic, interacts with external environment, afferent nerves, carry sensory signals from eyes, ears, skin, etc. To cns: carry motor signals from cns to skeletal muscles, efferent nerves, autonomic, regulates body"s internal environment, afferent nerves, carry sensory signals from internal organs to cns, efferent nerves, carry motor signals from cns to internal organs. Santiago ram n y cajal (1852-1934): a pioneer of neuroscience, became an anatomical researcher, used gogli technique (staining using silver salts) to see cells; has advantage of staining entire length of a single neuron. They receive information from other cells and carry it to the soma. Terminal buttons are button-like endings of the axon branch.
