This system receives information, interprets it, and decides on a response. The nervous system is formed by nervous tissue. Nervous tissue is found in every part of the body. This tissue is made up of one type of cell, neurons. Neurons have very long, thin structures through which they can send and receive messages. Neurons have a complex shape. Neurons are a type of cell with three parts: The body, which contains the nucleus and organelles. Dendrites, which are branched structures. With these structures neurons receive information from the sense organs or from other neurons. The axon, which transmits information to other neurons and sends orders to organs. Axons run beside other axons to form nerves. The nésnervous system is form Morataed by the central nervous system and the peripheral nervous system. The brain has three parts: • The cerebrum controls voluntary movements. • The cerebellum coordinates movements and maintains balance. • The brain stem regulates internal organs. The spinal cord controls reflex movements. The peripheral nervous system consists of nerves. It transmits information from the sense organs to the central CEIPnervous system and from theGi central nervous system to other organs.
