Document Summary
Made up of neurons: basic units of the nervous system; cells that receive, integrate, and transmit information in the nervous system. Operate through electrical impulses, communicate with other neurons through chemical signals and form neural networks. Work with thousands of neurons to create a neural network. Neural networks work together to create the nervous system. The different divisions are the central nervous system and the peripheral nervous system. Central nervous system (cns): brain and the spinal cord. Organizes information from pns and directs it. Peripheral nervous system (pns): all the other nerve cell in the rest of the body. Made up of the autonomic and somatic nervous systems. Powered by electrical impulses and communicate with other cells through chemical signals. Reception phase: take in the chemical signals from other neurons. Transmission phase: pass their own signals to another receiving. Sensory: detect information from the physical world and pass that info to the brain (spinal cord)
