THE NERVOUS SYSTEM By: Reece, Sheldon, Austin H

 The nervous system is made up of all of the nerve cells in your body, the nerve system is how we communicate with everyone and everything around us, without it we couldn’t communicate. At the same time many mechanisms inside our body are controlled. The nervous system takes the information from our senses, processes the information and triggers reactions, making muscles move, causes you to feel pain and all those fun things. If you touch a hot pot or a burner on a stove without the nervous system you would never know it was hot. The nervous system automatically send messages to you hand to make it pull back away from the heat and tells you that it is hot. What does the nervous system do?

 Central nervous system:  The central nervous system is the one that controls your brain and spinal cord. It is the side telling you the answers on the math test, the one making your palms all sweaty while you get ready for the test and the one that gives you that relieved feeling once you are done and hand it in.  Peripheral nervous system:  This is the side that controls all your limbs and muscles. Without this you couldn’t pick up a weight or extend your arm, or even walk.

 How does the nervous system work with other systems of the body.  The Nervous System Interacts with Other Systems in Your Body Skeletal System Digestive System Baroreceptors send the brain information on the blood pressure. The brain regulates the heart rate using the nerves. Cardiovascular System The brain monitors the respiratory volume and blood gas levels. The brain regulates respiratory rates Respiratory System Endocrine System The brain receives sensory information from the bladder. Urination is controlled by the brain. Urinary System The calcium from your bones helps your nervous system function.

 The cerebrum or cortex is the largest part of the human brain, The cerebral cortex is divided into four sections, called "lobes“ Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli Occipital Lobe- associated with visual processing Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech

Spinal Cord The spinal cord is a long, fragile tube-like structure that starts at the end of the brain stem and continues down almost to the bottom of the spine The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. It is also the center for reflexes. Cervical Nerves : (nerves in the neck) supply movement and feeling to the arms, neck and upper trunk. Thoracic Nerves: (nerves in the upper back) supply the trunk and abdomen. Lumbar Nerves and Sacral Nerves "S" : (nerves in the lower back) supply the legs, the bladder, bowel and sexual organs

 Nerves send information to your brain such has if something is hot or cold. And your brain also sends messages through your nerves such has lift the arm, left leg forward, right leg up, so on and so forth

The brain is what it is because of the structural and functional properties of interconnected neurons. The mammalian brain contains between 100 million and 100 billion neurons, depending on the species Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites. The cell body contains the nucleus and cytoplasm.

2 diseases Epilepsy is one, another word for it is seizure. Seizures may have many causes and not all seizures are epilepsy. High fevers in young children may trigger seizures which are short in time, they are easily controlled and, typically, have no permanent results. Epilepsy is a specific condition which may occur at any age, seizures are more intense, longer lasting in time. The condition may be controlled with medication, if the drugs do not work they may require surgery Alzheimer's disease Alzheimer’s is when you have total mind loss, you have no idea who comes and visits you. Alzheimer's is a type of disease that robs people of their memory. At first, people have a hard time remembering recent events, though they might easily recall things that happened years ago. People with Alzheimer's might forget their loved ones. They might forget how to dress themselves, feed themselves, and use the toilet. As time goes on, other signs can appear, including: Trouble focusing5 A hard time doing ordinary activities Feeling confused or frustrated, especially at night Dramatic mood swings -- outbursts of anger, anxiety, and depression Feeling disoriented and getting lost easily Physical problems, such as an odd walk or poor coordination Trouble communicating

6 fun facts - There are more nerve cells in the human brain than there are stars in the Milky Way. - If we lined up all the neurons in our body it would be around 600 miles long. - 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. - As we get older, the brain loses almost one gram per year. - The base of the spinal cord has a cluster of nerves, which are most sensitive. - The Nervous System can transmit impulses as fast as 100 meters per second.
