| Vibrations of the eardrum are then coupled by the middle ear ossicles, the three smallest bones in the body, to the fluid-filled cochlea. |
| These novel morphological approaches to the study of the ommatidia and the foregut ossicles may have limited application in the fossil record. |
| The arms of ophiuroids and crinoids are supported by calcitic ossicles reminiscent of vertebral centra. |
| One was in contact with the substratum, and the other formed a dome within the marginal ossicles, thus creating a body cavity. |
| Most such particles are echinoderm stem ossicles, brachiopods, bryozoans or other corals. |
| These contractions dampen the vibrations of the ossicles, thereby reducing the transmission of sound through the middle ear. |
