The term 'Anvil Bone' is composed of three parts: INCUS (5 letters), EAR (3 letters), and Ears (4 letters). INCUS is a small bone in the middle EAR that transmits sound vibrations from the eardrum to the inner EAR. The EAR is the organ of hearing and balance in vertebrates, which is composed of the pinna, auditory canal, eardrum, and ossicles. The Ears are the organs of hearing and balance in mammals, which are composed of the pinna, auditory canal, eardrum, and ossicles. Together, these three components make up the Anvil Bone, which is responsible for transmitting sound vibrations from the eardrum to the inner EAR.
