Leg - Tetrapod Legs

Tetrapod Legs

In tetrapod anatomy, leg is used to refer to the entire limb. In human medicine its precise definition refers only to the segment between the knee and the ankle. This segment is also called the shank, and the front (anterior) of the segment is called the shin or pretibia.

In bipedal tetrapods, the two lower limbs are referred to as the "legs" and the two upper limbs as "arms" or "wings" as the case may be.
