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 pass front manAffects nerves from the wag 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 advancing 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 remains 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. afterwardsal indicates the spinal cord being affected.Sclerosis describes unstatedened tissue that develops in the place of water-loving nerves.50,000 approxima tely people in the US, 5,000 new cases each year.Onset surrounded by ages 40-70, usually.Men have a slightly higher chance of ontogenesis ALS.Normally, neurons in the spinal cord and brain convey messages from the brain to muscles to cash in ones chips movement to the arms, legs, trunk, neck, and head. When the motor neurons die, the muscles cleart move, with weakness in result. passage 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 pledge 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 all the way or at all, to swallow, and to hold the head up. Eventually coughing and suspire become difficult.
