In lizards, the broken tail or limb is restored through the process of regeneration.

Regeneration is a process in which a few specialized cells called stem cells, repair and restore a severed body part. It is commonly observed in lower invertebrates like flatworms, cnidarians, etc. as a process associated with reproduction but in vertebrates, regeneration is restricted to the restoration or repair of an organ or body part only.

Lizards are vertebrate reptiles that can regenerate their broken tails or limbs through the process of regeneration.
