Document Summary

Neurons: one of the main type of cells found in the nervous system, that are responsible for sending and reciving messages throughout the body. Billions of these cells receive and transmit messages every day, including when you are asleep. The primary purpose of neurons is to fire , to receive input from one group of neurons and to then transmit that information to other neurons- this will allow them to work together and form a certain behaviour. Cell body (also known as the soma): the part of the neuron that contains the neucleus that houses the cells genetic material. Genes in the cell body synthesize proteins that form the chemicals and structures that allow the neuron to function. The activity of these genes can be influenced by the input coming from other cells. Dendrites: small branches radiating from the cell body that receive messages from other cells and transmit those messahes towards the rest of the cell.
