Muscular System

Toxic Myopathy

related to MD, caused by binge drinking or steroid abuse, toxins shut down the mitochondria in the muscle cells which become weak and start to degenerate

Skeletal Muscles

muscles attached to bone, function: movement posture, maintain body temperature

Sacromeres

contraction unit of a skeletal muscle,

Myofibils

made of repeating contraction units called sacromeres

Myofibers

makes up muscle, cell that contains multiple nucei and Myofibrils

Shin Splints

muscle sheering away from bone, causes inflammation and pain around tibia

Muscle Contraction

sliding filament model, nerve impulses tell myosin heads to pull the actin filaments towards each other, powered by ATP, once ATP has been broken down the myosin heads release the actin filaments and the scaromeer returns to original form

Cardiac Muscle

specialized muscle of the heart, function: to pump blood throughout the body

Smooth Muscle

walls of organs

Muscular Dystrophy

x linked genetic disorder where muscless weaken and degenerate over a short period of time
