  1. Muscle Notes

  2. Muscle System • Over 600 muscles in the human body

  3. Function • Movement of body • Complementary of skeletal system • Pump blood through body • Cardiac (heart muscle) • Move food through digestive system • Control movement of air in and out of lungs

  4. Functions, cont. • Complementary or opposing action • Muscles shorten to move skeleton (contraction) • Muscle groups include a flexor and extensor

  5. Types of Muscles • Smooth muscles (involuntary) -movement -digestion -lungs • Skeletal muscles (voluntary) -striped or striated -flexor/extensor • Cardiac Muscle (heart, Muscle) -pump blood through body -involuntary

  6. Smooth Muscle

  7. Skeletal Muscle

  8. Cardiac Muscle

  9. Problems with Muscle System • Lazy eye • Muscular Dystrophy -Wasting away of skeletal muscle -replaced by fat

  10. More Issues • -Muscle Strain -pulled muscle -tearing or stretching of muscle • -Bruise -discolored area under the skin caused by blood leakage due to injury • Tendonitis -inflammation of tendon due to over usage • Hernia -tearing of abdominal walls which allows the intestines to poke through the muscle walls.
