Document Summary

Neurons: one of the major types of cells found in the nervous system, that are responsible for sending and receiving messages throughout the body. Transmitting info to other neurons allows single neurons to work together in networks involving thousands of other cells; this eventually leads to some form of behaviour. Neurons transmit info to other groups of neurons. Parts of the neuron are specifically designed to receive information and parts designed for transmitting info to other cells. All neurons have a cell body which contains the nucleus that houses the cells genetic material. Genes in the cell body synthesize proteins that form chemicals and structures allowing the neuron to perform. Dendrites: receive messages from other cells and transmit those messages toward the rest of the cell. Neurons receive many impulses at once and these impulses travel to the axon hillock, which creates a chemical reaction that flows to the axon.
