Nervous System By: Sean Moran, Zach Persechino & Shannon Boyd

The nervous system is made up of the brain, spinal cord, and a network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. This system can be divided into two parts: the central nervous system and the peripheral nervous system.

The central nervous system is the processing center for the nervous system. It receives information and sends information to the peripheral nervous system. The two main organs of the central nervous system are the brain and spinal cord. The brain processes sensory information sent from the spinal cord. Both the brain and spinal cord are protected by three layers of tissue called the meninges. The peripheral nervous system carries information to and from the central nervous system. There are two types of cells in the peripheral nervous system. These cells carry information to and from the central nervous system. Cells of the sensory nervous system send information to the central nervous system from internal organs.

Each neuron receives an impulse and must pass it on to the next neuron and make sure the correct impulse continues on its path. Through a chain of chemical events, the dendrites pick up an impulse through the axon and transmitted to the next neuron. The entire impulse passes through a neuron in about seven milliseconds — faster than a lightning strike.

There are more nerve cells in the human brain than there are stars in the Milky Way. The left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body. An average adult male brain weighs about 1375 grams. An average adult female brain is about 1275 grams.

The Nervous System works with many other systems in your body they include: Skeletal System because the bones provide calcium that is essential for the function of the nervous system Respiratory System because the brain monitors respiratory volume and blood. Muscular System because receptors in muscles provide the brain with info about body positions and movements.
