Document Summary
Neurons one of he major types of cells found in the nervous system, that are responsible for sending and receiving messages through 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. Cell body (also known as the soma) the part of the neuron that contains the nucleus that houses the cells genetic material. Genes in the cell body synthesize proteins that form the chemicals and structure that allow the neurons to function. The activity of these genes can be influenced by the input coming from other cells. Dendrites small branches reading from the cell body that receive messages from other cells and transmit those messages toward the rest of the cell. At any given time, neurons will receive input from several other neurons.
