Document Summary
Neuron a nerve cell specialized for communication. The functioning of our brain depends on cross-talk among neurons. The cell body, also called the soma is the central region of the neuron. It manufacturers new cell components which consist of small and large molecules. It contains the nucleus, which is involved with protein manufacture; damage to this part of the neuron can be lethal to the entire cell. The cell body provides continual renewal of cell components. Dendrites branch like extensions for receiving information from other neurons. They spread out and listen in on conversations from neighbouring neurons and pass them on to the cell body. Axons the transmitters that send messages to other neurons. They are usually thin near the cell body, and this narrowness creates an area that"s easily activated by incoming signals. Synaptic vesicles travel the length of the axon on their way to a knoblike structure at its far end called the axon terminal.
