Document Summary

Nuerons are individual cells in the nervous system that receive and transmit information, glia cells are part of the nervous system that help insulate and enhance conduction of messages across the axon, they are present in the myelin sheaths. No, because they vary so much in terms of shapes and sizes, it is like trying to draw a tree. Describe the different components of a nerve cell. Soma: the cell body of the neuron, and it contains the nucleus. Dendrites: are the parts of the neuron that are specialize to receive information. Dendrites are usually great in numbers because a single neuron can receive signals from many other cells. Axon: it"s a long thin fibre in which the neuron"s signal is transmitted from one neuron to another, they can be very long. Myelin sheath: it"s the insulating material derived from glial cells and encases axons.
