Skeletal & Muscular System
The Skeletal System
Performs vital functions support, movement, protection, blood cell production, calcium storage and endocrine regulation.
Bones- support, protection, and movement
Ligaments- define range of motion, protect joints and bones, connect bone to bone.
Muscles- ability to contract and maintenance of proper posture
Tendons- soft tissue , and connects muscle to bone.
Nerves- communicate with brain through transmitters and conducts impulses
-paralyzation of bones
-pain in spine, and bones
-70% of adults between 55 and 78 years of age
-therapy is best
-when foot is pointed inward
-soreness and noticeable
-150,000-200,000-no real treatment besides surgery maybe
The Muscular System
It permits movement of the body, maintains posture, and circulates blood throughout the body.
How skeletal muscle contracts
Myositis: inflammation in the muscles
muscle weakness and muscle pain
effects less then 200,00 people a year
Muscular Dystrophy: Cause progressive weakness and loss of muscle mass. In muscular dystrophy, abnormal genes (mutations) interfere with the production of proteins needed to form healthy muscle.
Difficulty getting up from a lying or sitting position
Trouble running and jumping
Walking on the toes
Large calf muscles
Muscle pain and stiffness
1.3 to 1.8 per 10,000
no cure, but therapy slows down the disease
