  1. 1. The Muscular System Chapter 4 Lesson 2
  2. 2.

  4. 4. Moving the human body Muscle-an organ that contracts and gets shorter- this provides the force to move your body parts. Muscles of the body
  5. 5. Muscle Control • Voluntary musclesmuscles that you are able to control. • Examples are leg and arm muscles • Involuntary Musclesyou can not move them consciously. They just keep working. • Example- heart
  6. 6. Types of Muscles *Smooth *Cardiac *Skeletal
  7. 7. Smooth Muscles • Smooth muscles are non-striated • Involuntary movement • Move the internal organs • Contract and relax slowly. • Example- small intestine
  8. 8. Cardiac Muscle • Cardiac muscle are found only in the heart. • Involuntary movement. • Striations • Contracts about 70 times a minute every day of your life.
  9. 9. Skeletal Muscles • Skeletal Muscles-muscles that move bones. • Attached to the bones by tendons. • Most numerous in the body. • Look striped or striated. • Voluntary muscles.
  10. 10. How Muscles Work • Skeletal muscles-when one muscles contracts- another muscle relaxes. • Muscles always pull- never pushes. • Muscles use glucose (sugar) • Produce energy when they contract. • Muscles that are not exercised become smaller.
  11. 11. Muscles and bones work together
