Document Summary
Cells and structures: the anatomy of the nervous system. All of your organs and muscles are in communication with the nervous system, which is made up of cells. The most important of these are the neurons, arranged into neural circuits that underlie the simplest and the most complex of behaviors: neurons: also called nerve cell. The basic unit of the nervous system, each composed of receptive extensions called dendrites, an integrating cell body, a conducting axon, and a transmitting axon terminal. Each neuron receives inputs from many other neurons, integrates those inputs, and then distributes the processed information to other neurons. Glial cells provide a variety of support functions but also participate in information processing: glial cells: also called glia. Nonneuronal brain cells that provide structural, nutritional, and other types of support to the brain. Cajal was the first anatomist who was able to show that although neurons come very close together, they are not quite continuous with one another.
