ALS DISEASE Oral Notes :: essays research papers

ALS- Amyotrophic lateral sclerosisLou Gehrigs disease- Yankee B-Ball player 1903-1941Neurodegenerative disease- Unknown cause breaks tissue down in nervous system.Motor Neurons- they control heftiness military campaignAffects nerves from the brainiac to the spinal electric corduroy (upper motor neurons) then the lower spinal cord (lower motor neurons) which control muscle movement. With this disease, for unknown reasons, these neurons die, meaning a liberalist loss of the ability to move nearly any of the muscles in the body.Lou Gehrigs disease affects voluntary muscles, controlled by conscious thought, such as the arm, leg, and body muscles.ALS DOES NOT affect the heart muscle, or the smooth muscle of the digestive system, bladder, and other internal organs. Most keep eye movement as well.Amyotrophic- means the loss of muscle bulk. ulterioral indicates the spinal cord being affected.Sclerosis describes gravelyened tissue that develops in the place of hefty nerves.50,000 app roximately people in the US, 5,000 new cases each year.Onset surrounded by ages 40-70, usually.Men have a slightly higher chance of growth ALS.Normally, neurons in the spinal cord and brain convey messages from the brain to muscles to accomplish movement to the arms, legs, trunk, neck, and head. When the motor neurons die, the muscles batcht move, with weakness in result. going away of bulk is also a symptom. Loss of Lower motor neurons can make twitching.Two forms are known- Familial and sporadic.Familial accounts for about 10% of all Lou Gehrigs cases.Sporadic LGD has no known cause.The earliest scratch of LGD is weakness in arms or legs, and the throat and mouth muscles.-Speech slurred, hard to chew and swallow. Other early signs are twitching and muscle loss.Later symptoms lead to the loss of the ability to walk, use arms and hands, to speak clear or at all, to swallow, and to hold the head up. Eventually coughing and animated become difficult.
