The smallest muscle found in the human body is the stapedius muscle. This muscle is the smallest striped muscle of the human body. The stapedius muscle undergoes reflexive contraction in response to acoustic stimulation. It reacts to loud sounds.
Stapes is the smallest of the three ossicles of the ear. The other two ossicles are the Incus and the Malleus. The harmonized movement of these three ossicles allows for the amplification of sound.
