Title: Incudomalleolar joint
Content:  Incudomalleolar joint (more correctly called incudomallear joint) or articulatio incudomallearis is a small synovial joint between the malleus (hammer) and the incus (anvil). The joint's function is to transfer vibrations between the ossicles in the middle ear, which is perceived as sound. Contrary to other synovial joints the movement is very limited. All of the ossicles move more or less as a unit, at least at low frequencies. When the eardrum is moved inward due to sound vibrations, transferred through the outer ear, it transmits to the handle or manubrium of the malleus which is connected to the ear drum. The head of the malleus (caput mallei) moves with it and transfers energy/movement to the corpus of the incus (corpus incudis), which is located directly behind. The sound vibrations are then transferred to the stapes (stirrup) through the incudostapedial joint.
Title: Incudostapedial joint
Content:  Incudostapedial joint is a small, synovial ball-and-socket joint between the incus (anvil) and the stapes (stirrup). The joint's function is to transfer vibrations between the two ossicles. The incudostapedial joint lies between the long leg (long crus, or crus longum incudis) and the head of the stapes (caput stapedis). The long leg moves with the rest of the incus and a small knob, the lenticular process, articulates with the head of the stapes.
Title: Ossicles
Content: The malleus ("hammer") articulates with the incus through the incudomalleolar joint and is attached to the tympanic membrane (eardrum), from which vibrational sound pressure motion is passed. ; The incus ("anvil") is connected to both the other bones. ; The stapes ("stirrup") articulates with the incus through the incudostapedial joint and is attached to the membrane of the fenestra ovalis, the elliptical or oval window or opening between the middle ear and the vestibule of the inner ear. It is the smallest bone in the body. The ossicles are, in order from the eardrum to the inner ear (from superficial to deep): the malleus, incus, and stapes, terms that in Latin are translated as "the hammer, anvil, and stirrup".
Title: Incus
Content:  The incus is the second of the ossicles, three bones in the middle ear which act to transmit sound. It is shaped like an anvil, and has a long and short crus extending from the body, which articulates with the malleus. The short crus attaches to the posterior ligament of the incus. The long crus articulates with the stirrup at the lenticular process. The superior ligament of the incus attaches at the body of the incus to the roof of the tympanic cavity.
Title: Posterior ligament of incus
Content:  The Posterior ligament of the incus is a fibrous band that connects the tip of the short crus of the incus to the fossa incudis, running to the mastoid (posterior wall of the middle ear chamber). The posterior incudal ligament plays an important role in the vibration of the middle ear bones: together with the anterior ligament of the malleus, it forms a pivotal axis around which the ossicles rotate. This rotation conveys vibrations from the tympanum to the oval window on the bony labyrinth (where they can be transduced into electrical signals transmitted to the nervous system).
Title: Incus
Content:  The incus or anvil is a bone in the middle ear. The anvil-shaped small bone is one of three ossicles in the middle ear. The incus receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes medially. The incus is so-called because of its resemblance to an anvil (Incus).
Title: Malleus
Content:  The malleus is a bone situated in the middle ear. It is the first of the three ossicles, and attached to the tympanic membrane. The head of the malleus is the large protruding section, which attaches to the incus. The head connects to the neck of malleus. The bone continues as the handle (or manubrium) of malleus, which connects to the tympanic membrane. Between the neck and handle of the malleus, lateral and anterior processes emerge from the bone. The bone is oriented so that the head is superior and the handle is inferior.
Title: Malleus
Content:  The malleus, or hammer, is a hammer-shaped small bone or ossicle of the middle ear. It connects with the incus, and is attached to the inner surface of the eardrum. The word is Latin for 'hammer' or 'mallet'. It transmits the sound vibrations from the eardrum to the incus (anvil).
Title: Incus
Content:  Vibrations in the middle ear are received via the tympanic membrane. The malleus, resting on the membrane, conveys vibrations to the incus. This in turn conveys vibrations to the stapes.
Title: Incudostapedial joint
Content:  Although the joint is synovial, it nonetheless allows only for a very limited, linear range of motion. All of the ossicles move almost as a single unit. As the transfer of kinetic energy from the incident sound waves to the perilymph of the inner ear involves a loss of energy, the ossicular system functions to compensate for the loss by decreasing the lever ratio between the surface of the eardrum and base of the stapes, but also through the ratio between the manubrium mallei (the handle of the malleus) and the long leg of the incus. The ossicular system thus increases the force of transmitted oscillations by some 25-times between the tymphanic membrane and the base of the stapes.
