Where does the muscle attach (where is its origin and insertion)?
Use your text to find these points. Put a dot (or line) for the origin and a dot (or line) for the insertion on the skeletal diagram provided. Use Anterior, Lateral or Posterior View according to the muscles location; note that superficial muscles are on the left and deep muscles on the right. B. Use a colored pencil to connect the origin and the insertion. This is the LINE OF PULL and represents the direction in which the muscle will exert its force. The point of the arrow should be pointing toward the origin. C. Label each muscle, using parallel lines or use a color-coded legend.
