关于此电子书
Through engaging, easy-to-read text, young readers learn that the human body's nervous system is like a supercomputer that coordinates all of the body's actions and reactions. Both the central nervous system and the peripheral nervous system, as well as their parts are discussed. Readers discover that the brain and the spinal cord make up the central nervous system and that the spinal cord connects the brain to the peripheral nervous system, which contains all the nerves in the body. The book explains that the nervous system makes the heart beat, keeps us breathing, and allows us to see and read. The brain's various parts, the cerebrum, the cerebellum, the brain stem, the hippocampus, the pituitary gland, and the hypothalamus, are also discussed, as well as the functions of these various parts, including control of our voluntary and involuntary muscles, control of our memory, sending growth hormones throughout the body, and regulating the body's temperature. A detailed diagram of a labeled neuron is included. Kid-friendly text and a graphic explanation describe how pain messages throughout the body. Senses, reflexes, and diseases that cause the nervous system to function improperly, such as multiple sclerosis and epilepsy, are also discussed. Common brain and spinal cord injuries and the ways to avoid these injuries are also highlighted. Readers also learn about the nutrients necessary to keep the nervous system working properly. These include glucose, fat, protein, vitamins, and minerals. Full-color photos, detailed diagrams, medical models, phonetics, glossary, and index enhance the text.
