Limb

A limb is an appendicular structure used for support, movement, manipulation, flight, or other functions depending on the animal.

In comparative osteology, limbs are studied through their bones, joints, proportions, and relationship to locomotion.

Limb structure helps visitors connect skeletal form with movement.

A limb can show:

  • support
  • leverage
  • stride
  • grasping
  • flight
  • swimming
  • digging
  • weight-bearing

When observing a limb, ask:

  • Which segments are present?
  • Which bones are long, short, fused, or reduced?
  • How do the joints appear to move?
  • How does the limb compare with another animal’s limb?

Ask students to compare a bird wing, mammal forelimb, and human arm model. What is similar? What is modified?
