Document Summary

Neurons: specialized cells that are the basic building blocks of the nervous systems. Theses cells link together like a circuit. Each neuron has 3 main parts: cell body (soma) Contains the biochemical structures needed to keep the neurons alive and its nucleus carries the genetic information that determine how the cell develops and functions: dendrites. Brank like fibers that acts like antennas that collect messages from neighboring neurons and send them on to the cell body: axon. Conducts electrical impulses away from the cell body to other neurons, muscles, or glands. The axon branches out at its end to form a number of axon terminals. Each axon may connect with dendritic branches. There are more than 200 types of neurons. Neurons are supported in their functions by glial cells: glial cells: surrounds neurons and holds them in place. Also manufactures nutrient chemicals and forms the myelin sheath. The glial cells outnumber neurons about 10 to 1.
