Nature, 1962
FEW problems in morphology have aroused more interest than that of the origin of the ear ossicles. It is a familiar fact that the Mammalia differ from all other gnathostomes in having a chain of three ossicles (stapes, incus, and malleus) serving to convey vibrations from the tympanic membrane to the labyrinth lodged in the auditory capsule.

Photomicrography of the middle ear ossicles
The Journal of the Acoustical Society of America, 2019I removed temporal bone sections from human cadavers with the help of my colleagues. From there, I utilized a Dremel tool to access the otic capsule and remove the malleus, incus, and stapes from each section. Not all attempts were successful due to the fragile nature of these bones.

Middle Ear Ossicles of Australian Aborigines
Archaeology in Oceania, 1982in this study are listed by sex and region in Table 1. The first sample comes from various parts of Western Australia and the four subdivisions used are those delineated in two previous studies of Western Australian Aboriginal skulls and teeth (Margetts and Freedman 1977, Freedman and Lofgren 1981). The second sample is from the Murray Black Collection

Rotation of middle ear ossicles during cetacean development
Journal of Morphology, 2001AbstractCetacean middle ears are unique among mammals in that they have an elongated tympanic membrane, a greatly reduced manubrium mallei, and an incudal crus longum that is shorter than the crus breve. Elongation of the tympanic membrane and reduction of the manubrium is thought to be related to an evolutionary rotation of the incus and malleus out ...

The phylogeny of the middle ear ossicles
Indian Journal of Otolaryngology, 1988Morphology of the ossicles tends to show adaptation to the need of the animal, as one traces the phylogeny existing in vertebrates. Tumarkin (1948) has described the vestibulo-ossicular and vestibulo-quadrate mechanisms from primitive vertebrates. It is interesting to observe how the vestigeal organs have cleverly adapted to serve the perception of the

A study of the human ear ossicles
Indian Journal of Otolaryngology, 19731. Detailed observations have been recorded on incus, malleus and stapes of 50 temporal bones of adult human males. 2. Gross malformations of the ear ossicles, in the form of partial or complete absence have not been observed. 3. The average measurements of the stapes are lower, as compared with observations of other workers.

[Kinematics of the ear ossicles].
Vestnik otorinolaringologii, 1995The paper details the movements of the auditory ossicula in exposure to low- and high-frequency sounds. Low-frequency sound causes the hammer to vibrate along the line crossing the tympanic anterior and posterior folds. Because of the screw shape of the anvil-hammer junction these hammer movements produce dislocation of the long anvil process along the

Densitometry of implanted allograft ear ossicles.
Revue de laryngologie - otologie - rhinologie, 1990Densitometry measurements of allograft ear ossicles implanted in humans middles ears for more than 10 years have been performed by means of High Resolution Computerized Tomography and compared with similar measurements made in the opposite normal middle ear ossicles.

[Dentin ossicle prostheses (DOP)--a new concept in replacing the ear ossicles].
Laryngologie, Rhinologie, Otologie, 1988The variety of materials used for replacement of the ossicles is proof enough that no single material can satisfy all criteria: availability, mouldability, stability and biocompatibility. The trouble-free availability as well as the excellent mouldability enable the development of a principle of preparation of ossicular replacement prosthesis from ...

[Functional model of the middle ear ossicles].
Kaibogaku zasshi. Journal of anatomy, 2009In students' dissection practice, it is very difficult to teach students the structures and functions of the middle ear ossicles. The middle ear ossicles are too small to explain their structures and functions. Models are useful in explaining these points, but there have been no models that accurately explain the movements of the middle ear ossicles ...
