The term 'Malleus or Hyoid' refers to two different bones. The Malleus is a small BONE located in the middle ear and is part of the auditory ossicles, which are three tiny bones that transmit sound from the outer ear to the inner ear. The Hyoid is a U-shaped BONE located in the neck and is the only BONE in the body that does not articulate with any other BONE. It serves as an anchor for muscles of the tongue, larynx, and pharynx. Both the Malleus and the Hyoid are four letter words, with the Malleus spelled M-A-L-L and the Hyoid spelled H-Y-O-I-D.
