Document Summary
Neuron is a cell in the nervous system whose function it is to receive and transmit information. Soma contains the nucleus of the cell alive. Dendrite, which is a branching, treelike fiber, collects information from other cells and send the information to the soma; and a long, segmented fiber known as the axon. Axon transmits information away from the cell body toward other neurons or to the muscles and glands. Terminal button is at the tip of each axon branch. Synapses is the spaces between the cells. Dendrites receive signals from other neurons via synapses. This information is the processed in the cell body/ soma, and if the signal is strong enough, the message is pushed through and travels down the axon. The signal travels to the end of the axon to the terminal buttons where another signal triggers neurotransmitters to be released, passing through the synaptic cleft onto the dendrites of another neuron.
