The nervous system By: Mercedes Trowell Facts about the nervous system The nervous system is responsible for coordinating and regulating activities of the cells The nervous system is divided into two parts, the central nervous and the peripheral nervous systems Basically the nervous systems job is to send messages from one cell to the other The spinal cord flexes your body and tells your spine to move Major organs of the nervous system There are two major organs to the nervous system: 1. The Brain The brain controls your entire body. For 1. Spinal Cord The spinal cord controls your reflexes for example if someone were to step on your foot your brain receives the message that comes from your sensory neurons and tells you to say ouch. example, When your at the doctors office and they tap your knee with the hammer and you kick your leg that is because the nerve in your knee is connected to your spinal cord Functions of the nervous system The nervous system has three major functions: Sensory Neurons- function is to receive information from the sensory receptors Interneurons- their job is to transfer and intercept impulses Motor Neurons their job is to send the appropriate impulses to the muscles and glands. Nervous system pictures The brain controls the entire body The spinal cord controls the movements of your body The peripheral nerve connects the nerves in your limbs to the spinal cord Responsibility of the nervous system The brainstem takes in, sends out, and coordinates all of the brain's messages. It also controls many of the body's automatic functions, like breathing. Questions well hmmm I guess I am done so any questions.
