Document Summary
Nervous system- complex communication networks in which signals are constantly being transmitted, received and integrated behaviour depends on rapid information processing. The 2 types of nervous system cells are . Glia- glue ; provide structural support, nourishment and insulation for neurons: involved in the removal of waste, helps maintain the chemical environment of the neurons. Neurons- the individual cells in the nervous system that receive, integrate (put together) and transmit information: basic links that permit communication. Soma- or cell body; contains the cell nucleus and much of the chemical machinery common to most cells used for handling information. Dendrites- the parts of a neuron that are specialized to receive information (branch-like) Axon- a long, thin fibre that transmits signals away from the soma, to other neurons or to muscles or glands branch off to communicate with a number of other cells.
