ossicle

Using a dissecting scope, I was able to identify a few things, including a complete ear ossicle.

Behind them others poured in a countless army, crowding and mantling every ossicle.

The ligament connecting the two valves is in an internal groove and the hinge has a free ossicle.

Under polarized light the ossicle behaves as if it were a single crystal because the axes of all the crystals are parallel.

The second ossicle which receives the hammer blows is the incus ("anvil" L).

There are about twenty short cirri, banded and arranged in transverse rows on a central raised ossicle.

The incus or anvil is the anvil-shaped small bone or ossicle in the middle ear.

When an ossicle becomes redundant, specialised cells known as phagocytes are able to reabsorb the calcareous material.

In reptiles, birds, and early fossil tetrapods, there is only a single auditory ossicle, the stapes.

There never had been any discernible damage to the auditory nerves, no apparent disorder to the ossicle, cochlea, or eardrum of either ear.

Water enters the system through the madreporite, a porous, often conspicuous, sieve-like ossicle on the aboral surface.

In many amphibians, there is also a second auditory ossicle, the operculum (not to be confused with the structure of the same name in fishes).

If the tiny muscles attached to them are damaged, or if the nerves leading to those muscles are, the ossicle movements become somewhat erratic.

Chronic ear infection (a fairly common diagnosis) can cause a defective ear drum or middle-ear ossicle damages, or both.

Each ossicle is composed of microcrystals of calcite arranged in a three-dimensional lattice known as a stereom.

"They have no outer ear-in itself not too important, but they have no ossicle and no tympanic cavity.

Because in doing so it strikes again and again on the second bone, this first ossicle is called the matteus (mal'ee-us; "hammer" L).

As sound waves vibrate the tympanic membrane (eardrum), it in turn moves the nearest ossicle, the malleus, to which it is attached.

A cirrus (plural cirri) is an articulated appendage projecting from an ossicle that forms part of the stalk of a crinoid.

There are a number of cirri or unbranched appendages on a low, cone-shaped dorsal ossicle, a bone-like structure in the centre of the disc.

Ossicle dates to c. 1570, from Latin ossiculum, a diminutive of Latin os "bone" (Genitive: Ossis).

Another specific wormian bone, the pterion ossicle, sometimes exists between the sphenoidal angle of the parietal bone and the great wing of the sphenoid bone.

The malleus or hammer is a hammer-shaped small bone or ossicle of the middle ear which connects with the incus and is attached to the inner surface of the eardrum.

All non-mammalian amniotes use this system including lizards, crocodilians, dinosaurs (and their descendants the birds) and therapsids; so the only ossicle in their middle ears is the stapes.

Using this approach, in a series of publications, Feduccia analyzed the morphology of the bony stapes, the ear ossicle of birds, to help elucidate the interrelationships of passeriform birds.
