The Nervous System Your bodies control center What does it do? • The nervous system is a network of cells which allow the brain to communicate with all other organs What makes up the Nervous system ? • Central Nervous • System (CNS) Peripheral Nervous System (PNS) Central Nervous System • Brain: weighs about 3 pounds and is composed of 10 Billion neurons that control all actions, thoughts, and memory. • Spinal Cord: Long bundle of neurons which relay messages to and from the brain Brain Vocabulary • • • • • • CEREBRUM – The largest portion of the brain; controlling the senses, movement of muscles, thinking, and speech. CEREBELLUM – Section near the brain stem that controls balance, posture, and coordination. BRAIN STEM – Controls some important automatic body functions such as heartbeat, breathing, blood pressure and digestion. NERVE – A bundle of neurons that act like an electrical cord moving signals through the nervous system. NUERONS – Specialized cells that send quick messages through the brain and body. NERVOUS SYSTEM – Controls all of your body’s actions. Peripheral Nervous System • The PNS is made up • of the nerves that branch out from the spinal cord to the body There are two different kinds of PNS nerves: Somatic & Autonomic Somatic & Autonomic Nerves • • Somatic Nerves: A nerve dealing with an action you have control over (i.e. legs & arms) Autonomic Nerves: A system dealing with actions you do not usually control (i.e. breathing & digesting) Problems • Head injuries kill brain neurons which cannot be replace • Spinal cord injury can result from damage to the head, neck or body. Paralysis of all or part of the body may occur. • Nerve inflammation (“pinched nerve”) can follow a minor injury and cause pain in a single part of the body such as the elbow, back or shoulder. • Diseases unrelated to injuries can also attack the nervous system. Examples: Brain Tumor, Epilepsy, Multiple Sclerosis, Alzheimer’s Disease Care • SLEEP: your NS needs rest and sleep to function properly. • AVOID ALCOHOL & DRUGS: Alcohol and many other drugs may destroy brain cells and interfere with clear thought and emotional stability. • PLAY SAFELY: Wear appropriate safety helmets and equipment. • SAFETY BELT: Click it whenever you are in a moving vehicle.
