Range of Movement

By the end of this lesson, I will be

able to:

Understand how muscles work together to move my bones.

Know the different ranges of movement my body allows.

Recap

How do we move?

  • Muscles pull on our bones.

  • One contracts while the other relaxes.


Muscles as pairs l.jpg
Muscles as Pairs

  • Muscles work in pairs-

    antagonistic muscle action.

  • The muscle that contracts is known as the primemover or the agonist (In agony!!).

  • The muscle that relaxes is known as the antagonist.

  • The prime mover is also helped by other muscles called synergists which hold the body in position for the prime mover to work smoothly.

Muscles as Pairs

  • A voluntary muscle usually works across a joint.

  • It is attached to both bones by strong cords called tendons.

  • When a muscle contracts, usually one bone moves.

  • The other is stationary.

  • The origin is where the muscle joins the stationary bone.

  • The insertion is where the muscle joins the moving bone.

  • When a muscle contracts, the insertion moves towards the origin.
