Document Summary

How do they interact? (e. g. as in figure 2. 10) A sensory neuron is neurons that detect external and internal environment and sends and receive these information to the central nervous system. A motor neuron controls the contraction of muscles and secretion of glands. An interneuron lies entirely within the central nervous system: local interneuron form circuit with nearby neurons and analyse small piece of information, relay interneuron connect local interneuron from one region of the brain to another. Cns is called the central nervous system which consist the brain and spinal cord. Soma(cell body) contains the nucleus and support the life processes of the cells. Axon transfer message from the cell body to the terminal button. Axon hillock a specialized part of the cell body that connects to the axon. Trigger zone the area at the axon hillock where action potential occurs when the threshold is reached. Myelin a sheath that surrounds the axon to insulate one axon from another.
