Tendons of the hand.
You can see muscles on the dinner table; for they are only lean meat.
They are fastened to the bones by strong cords, called tendons (tĕn´dŏnz). These tendons can be seen in the leg of a chicken or turkey. They sometimes hold the meat so firmly that it is hard for you to get it off. When you next try to pick a "drum-stick," remember that you are eating the strong muscles by which the chicken or turkey moved his legs as he walked about the yard. The parts that have the most work to do, need the strongest muscles.
Did you ever see the swallows flying about the eaves of a barn?
Do they have very stout legs? No! They have very small legs and feet, because they do not need to walk. They need to fly.
The muscles that move the wings are fastened to the breast. These breast muscles of the swallow must be large and strong.
EXERCISE OF THE MUSCLES.
People who work hard with any part of the body make the muscles of that part very strong.
The blacksmith has big, strong muscles in his arms because he uses them so much.
