  2. Involuntary Muscles Involuntary Muscles Muscles that are not under your conscious control. Examples - heart, muscles used for breathing

  3. Voluntary Muscles • Muscles that are under your conscious control. • Examples – smiling, turning a page in a book, and standing up.

  4. Skeletal • Are attached to the bones of your skeleton and provide the force that moves your bones. • They are Striated • Striated - banded

  5. Smooth • Involuntary muscles such as those in your stomach that aid in digestion.

  6. Cardiac • Found in your heart. • It is involuntary, and striated.

  7. Contraction • Muscle cells can only contract, not extend , so skeletal muscles must work in pairs. • While one contracts the other muscle relaxes to its original length.

  8. Exercise • Exercise makes muscle cells grow in size. As a result, the whole muscle becomes thicker, and therefore stronger.

  9. Tendons • Tendons are strong connective tissue that connect muscle to bone.
