We, the human beings, are the medium-sized member in the Mammal group of this world. We bear in our body the smallest bone that measures only 3mm in length and 3mg in weight! It is the Stapes bone (Stirrup bone). It is one of the three auditory ossicles (bones) found in the Middle ear of us, one on each side. It is the innermost bone. The other bones are the Incus present in the middle and the Malleus in the outer side.
