THE MUSCULAR SYSTEM Advanced Health -Pacheco

Voluntary Movement Involuntary Movement

Contraction (shortening of a muscle) – Isometric – Eccentric – Concentric Extension (stretching of a muscle)

Cardiac muscle: striated muscle that forms the wall of the heart Skeletal muscle: attached to bone by tendons ; voluntary movement by use of flexors and extensors Smooth muscle: act on the lining of passageways and internal organs

Physical activity – Prevents atrophy (decrease in size and strength) Protective wear

Contusion (Bruise) Sprain vs Strain Tendonitis

Muscular Dystrophy - genetic disorder - muscle fibers are eventually destroyed
