3.3. How do we use our muscles

IDevice Icon 3.3. How do we use our Muscles





Each muscle has a special job:

  • We use the deltoid muscle to raise our arms.

  • We use our abdominal muscles to bend at the waist.

  • The quadriceps and gemellus work together when we walk or run.

  • We use the trapezius to raise our shoulders.
