  • Posture.
  • Circulation.
  • Respiration.
  • Digestion.
  • Urination.
  • Childbirth.

What are the 5 major functions of muscles?

The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation:

  • Movement. Skeletal muscles pull on the bones causing movements at the joints.
  • Support. Muscles of the body wall support the internal organs.
  • Protection.
