Organs in the Nervous System

The Organs that make up the nervous system are the Brain, the Spinal Cord, and the peripheral nervous system throughout the body.

The Brain

The brain is made of over 100 billion nerves that work together in many ways. The brain is made up of three main parts: the forebrain, midbrain, and hindbrain. The brain sends all signals to the spine to perform actions.

The Spine

The spine is made up of nerves that run up and down the spine. The spine sends the signals that are sent from the brain to the parts of the body that are requested to move. Its sends signals from the brain every second. Every movement of the body is moving because of signals that resonate from the nerves of the spine.

Peripheral Nervous System

The function of the peripheral nervous system is to connect the central nervous system to the limbs and organs.

How it all works

All organs in the nervous system work together to send signals all around the body to tell other organ systems what to do, what muscles are to be moved, and what actions should be performed in the body.

Diseases/Disorders

Diseases associated with the nervous system are Alzheimer's Disease, Epilepsy, Parkinson's, Muscular Dystrophy, and Multiple Sclerosis.

Alzheimer's Disease

Alzheimer's Disease is the slow degeneration of brain tissue that causes a person to lose social and even intellectual skills. Over time memory loss, disorientation, and loss of the ability to use judgment is what Alzheimer's will cause.

Epilepsy

Epilepsy is a neurological disorder that causes seizures from a misfired electrical impulse in the brain. Epilepsy causes uncontrollable jerking movements, confusion, and blank staring spells. Epilepsy can also cause seizures that can become very .

Parkinson's Disease

Parkinson's is a neurological disease that affects the bodies ability of movement and is believed to be caused by genetic mutations. This causes the trembling of hands, movement being slowed, change in speech, and memory loss. Over time, daily tasks become more difficult.

Muscular Dystrophy

Muscular Dystrophy is the degeneration of muscles over time and is commonly due to genetic deficiency of dystrophin, a muscle protein. Muscle weakness, frequent falls, progressive crippling, and lack of coordination are all symptoms of MD.

Multiple Sclerosis

Multiple Sclerosis affects the central nervous system and leads to eventual paralysis. MS occurs when the body's immune system attacks a protective layer on the nerves and this disturbs signals between the brain and the body. Symptoms are blurred vision, double vision, or even a distortion of the colors red and green.
