5.7.1- Recall the way in which muscles, tendons, the skeleton and ligaments interact to enable movement including antagonistic muscle pairs, extensors and flexors.

  • Cartilage: a tissue made from collagen, which protects bone ends
  • A muscle: an organ that produces movement by contraction
  • A joint: the junction between two bones
  • A tendon: joins muscle to bone
  • A ligament: joins bone to bone to stabilise a joint

Muscles work in pairs. One muscle produces the opposite movement from the other muscle, therefore, the pairs are called antagonistic pairs.

Muscles which cause a joint to extend are called extensors, muscles which cause a limb to retract are called flexors.
