The auditory ossicles are associated with the tympanic membrane (eardrum) on the malleus/hammer side and the oval window in the stapes/stirrup side. The base rises from the temporal bone and these "little bones" are exposed to the air environment of the middle ear.
The associated bones of the skull include the mandible (jawbone), hyoid bone, and auditory ossicles (malleus, incus, and stapes).
The auditory ossicles are located in the middle ear. Their function is to transmit and amplify the sound vibrations from the tympanic membrane (eardrum) to the oval window.· tympannic side = malleus or hammer· middle = incus or anvil· oval window side = stapes or stirrup
The middle ear contains the auditory ossicles, consisting of the malleus, incus, and stapes, which transmit sound vibrations from the eardrum to the inner ear. The middle ear is an air-filled space located behind the eardrum and helps amplify these vibrations before they reach the cochlea. Proper functioning of the auditory ossicles is essential for normal hearing.
The now fluid vibrations will stimulate the mecanoreceptors turning the vibrations into electrical energy which will then be sent by the auditory nerve (cranial nerve #8) to the brain for interpretation.
The necessary anatomical structures within the middle ear for the detection of sound include the tympanic membrane, the three auditory ossicles, and the two muscles that control the resonance of the ossicles. The three auditory ossicles (ie bones of the ear) are the malleus, incus, and the stapes. The tensor tympani muscle pulls on the malleus and the Stapedius muscle pulls on the stapes. The tension and relaxation of these two muscles control the amplification of sound. This acts to protect against the damage loud noises can cause to the inner ear.

auditory ossicles
The term "ossicles" literally means "tiny bones" and commonly refers to the auditory ossicles, though the term may refer to any small bone throughout the body. The three auditory ossicles are the hammer, stirrup, and anvil.

The vibrations received by the tympanic membrane are transferred to the oval window by the three auditory ossicles: the malleus, incus, and stapes. These ossicles amplify and transmit the sound waves from the eardrum to the inner ear for processing.
Fusion or fixation of the ossicles is where one or more of the three auditory ossicles cannot transmit sound vibrations for a variety of reasons. This does cause "conduction" deafness or hearing loss.

Auditory ossicles of the ear are the smallest bones of the body.

There are three auditory ossicles in each ear: the malleus, incus, and stapes. These three tiny bones are located in the middle ear and transmit sound vibrations from the eardrum to the inner ear.
Spongy bone growing between the auditory ossicles is called otosclerosis. This is one of the causes of Conductive Deafness or Hearing Loss where the ossicles are not able to "conduct" the sound vibrations from the eardrum to the oval window. The spongy bone "dampens" the vibrations instead of amplifying them.
