The Muscular System
By Maya Myers
Some organs and functions in the Muscular System
Involuntary- Smooth muscles that cannot be controlled by will.
Voluntary- muscles whose actions can be controlled voluntarily.
Some functions of the muscular system are skeletal movement, blood pumping, and heart beating.
Some tissues in the muscular system are:
Skeletal Muscle Tissue-movement of tissue of a facial expression under conscious control.
Cardiac Muscle Tissue-pumping of blood through the heart; Alternate contraction and relaxation.
Smooth Muscle Tissue-controls slow, involuntary movements such as the contraction of the smooth muscle tissue in the walls of the stomach and intestines.
What are some diseases in the muscular system?
Dermatomyositis- autoimmune disease causing skin rash and muscle weakness.
Muscular Dystrophy- genetic disease that renders muscle fibresmore vulnerable to damage than normal.
Compartment syndrome- the result of too much pressure building up around the muscles causing severe pain and sometimes cellular death.
Rhabdomyolysis- causes muscle fibbers to break down to get absorbed into the bloodstream. Alcoholism, drug abuse, and heatstroke are several known causes.
treatments: there is no known cure for it.
Symptoms: frequent falls, walking on the toes, and muscle pains.
causes: genetic mutations particular to that type of the disease.
