Document Summary
The human body is composed of many different types of cells. Psychologists are most interested in neurons: one of the major types of cells found in the nervous system, that are responsible for sending and receiving messages throughout the body. 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. Doing so allows single neurons to work together as part of networks, involving thousand and even millions of other cells, this will eventually lead to some form of behavior. All neurons have a cell body also known as a soma, is the part of a neuron that contains the nucleus that house the cell"s genetic material. Genes in the cell body synthesize proteins that form the chemical and structures that allow the neurons to function. The activating of these genes can be influenced by the input coming from other cells.
