Sample answer

  • Ball and socket joints have a rounded head of one bone fitting into a cup-like socket of another bone which allows movement in multiple planes.
  • Hinge joints primarily allow movement in one plane, however, ball and socket joints permit flexion, extension, abduction, adduction, rotation and circumduction.
  • For example, the hip joint allows the leg to move in all directions while the hinge joint of the knee only allows flexion and extension, demonstrating how structural differences impact movement capabilities.
