| | Since these ossicles are strongly attached to that bone of the thumb, they are convex on the outside and resemble the part of a bone which puts forth ligaments and receives the insertion of tendons. | | | That this ossicle was called Albadaran by the Arabs and by the truly occult and shadowy philosophers is better known by superstitious men than by students of anatomy, who may also be able to compare the fourth bone of the carpus [os pisiforme] to a chickpea. | | | In the inspection of muscles rather than bones, I have found no unsatisfying number of these ossicles, as much in the foot as in the hand, since most and in fact nearly all are attached to tendons. |

| | TPOS - The Middle Ear |
| | One, the tensor tympani, is inserted on the medial surface of the malleus, and when it contracts, it pulls the bone inward. | | | The tensor tympani muscles also help to keep a steady tension on the eardrum, which makes sure that the transmission of vibrations to the ossicles is effective. | | | This reflex makes the muscles act, pulling on the malleus and stapes, making the chain of ossicles in the middle ear more rigid and less effective in transmitting vibrations to the inner ear. |

| | Four of the 6 foals had ossicles in at least one foot, all of which had "healed" completely by 14 months of age. | | | So whenever these wing fractures or ossicles are found in sucklings, weanlings, or yearlings, they should simply be given time to heal; surgery, confinement, and shoeing changes are usually unnecessary. | | | This common phenomenon in foals may be a traumatic form of developmental bone disease, and could be considered to be a sentinel for nutritional or other pasture footing problems (ground too hard, too many socks, etc.). |

| | If a high-frequency sensorineural hearing loss occurs, an iatrogenic injury from the transmission of mechanical or acoustic trauma to the inner ear during surgery may be present. | | | In general, the inner ear is not affected because its development is complete by the time the ear canal begins to form. | | | Patients with severe CAA have total canal atresia and usually present with unfavorable middle ear anatomy and temporal bone development for reconstruction. |

| | The Ossicles and Their Function |
| | The vibration of the eardrum is transmitted to the oval window of the inner ear by means of the ossicles, which achieve an amplification by lever action. | | | This lever action is thought to achieve an amplification by a factor of about three under optimum conditions, but can be adjusted by muscle action to actually attenuate the sound signal for protection against loud sounds. | | | The ossicles can be thought of as a compound lever which achieves a multiplication of force. |

Vibrations in the stapes at the oval window causes motion in a fluid within the inner ear to stimulate the hearing receptors. | | | The auditory ossicles - the "malleus" (hammer), "incus" (anvil), and the "stapes" (stirrup) - are attached to the wall of the tympanic cavity in the ear by tiny ligaments and are covered by mucous membrane. |

| | Otosclerosis |
| | Otosclerosis can also affect the other ossicles (malleus and incus) and the otic capsule -- the bone that surrounds the inner ear. | | | The ossicles become knit together into an immovable mass, and do not transmit sound as well as when they are more flexible. | | | A bony ankylosis (knee) knits the bone of the middle ear to the stapes, preventing normal transmission of sound from the eardrum into the inner ear. |

| | Hearing Impairment |
| | A blockage or other structural problem interferes with how sound gets conducted through the ear, making sound levels seem lower. | | | For example, a tear or hole in the eardrum can interfere with its ability to vibrate properly. | | | People also get conductive hearing loss when key parts of the ear - the eardrum, ear canal, or ossicles - are damaged. |
