Vestigial organs are the organs that once was useful in an animal's evolutionary past, but that now is useless or very close to useless.
Human body has about 90 vestigial organs. These included the muscles of the ear, wisdom teeth, the appendix, the tail bone,body hair, and the semilunar fold in the corner of the eye (Plica semilunaris). Malleus is one of the 3 bones present in inner ear. It receives vibrations from the tympanic membrane and transmits this to the incus.
