Multiple Sclerosis Multiple sclerosis is an autoimmune‚ is a chronic‚ often disabling disease that attacks the central nervous system (CNS)‚ which is made up of the brain‚ spinal cord‚ and optic nerves. Symptoms may be mild‚ such as numbness in the limbs‚ or severe‚ such as paralysis or loss of vision. The progress‚ severity‚ and specific symptoms of MS are unpredictable and vary from one person to another. Today‚ new treatments and advances in research are giving new hope to people affected by

to grow on the nervous tissue. These tumors can occur anywhere in the nervous system‚ this includes the brain‚ nerves‚ the spinal cord‚ skin‚ and many more of the body’s systems. These tumors tend to be benign or in other words they are non-cancerous. The development of these benign tumors may cause skin and or bone abnormalities. These tumors‚ also known as neurofibromas‚ form on nerves along the body and they also form underneath the skin. As the tumors increase in size‚ they may press against vital

Emily Muñoz 1/7 period Nervous System The nervous system consist of all the nerves the body has. Controlling not only the actions the body takes but the emotions a human being feels. The spinal cord‚ brain‚ and many nerves revolve around the nervous system. There are three overlapping functions that use millions of sensory receptors‚ that monitor the body. By monitoring the body the functions detect any changes the human body has had.Two components separate the nervous system allowing us to focus

it to different parts of the body. It does this via the spinal cord‚ which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. For example‚ if you accidentally touch a hot stove‚ the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily

system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response The nervous system has two distinct parts -- CENTRAL and PERIPHERAL. The central part is made up of the brain and spinal cord. The peripheral part of the nervous system is said to be peripheral because it is outside the central nervous systems. The human nervous system contains approximately 10 billion nerve cells. These neurons

Also called median nerve entrapment‚ CTS occurs when the median nerve‚ a major nerve running from the forearm to the hand‚ is compressed‚ causing heightened and even painful sensations to the palm and wrist. The median nerve is mainly in charge of the hand movements‚ controlling impulses to the hand muscles and the sensations felt in the palm and fingers. The carpal tunnel‚ then again‚ is a narrow passageway of ligaments found in the base of the hand‚ and is where the median nerve can be found. Too

It must be a neurological problem involved with the synaptic centers. Since Annie is having such problems when she is working out hard and just playing around
