Definition of ossicle in English: ossiclenoun ˈɒsɪk(ə)lˈɑsək(ə)l Anatomy Zoology 1A very small bone, especially one of those in the middle ear. Example sentencesExamples - Sutural bones are usually small, irregularly shaped ossicles, often found in the sutures of the cranium, especially in the parietal bones.
- The middle ear ossicles and tympanic membrane remained intact, so sound stimulation could be applied to the preparation through a loudspeaker connected to the external ear canal.
- Vibrations of the eardrum are then coupled by the middle ear ossicles, the three smallest bones in the body, to the fluid-filled cochlea.
- Sound waves reaching the tympanic membrane will initiate vibrations that are transmitted through the bony ossicles of the middle ear to the oval window.
- Internally, the mastoid is hollowed out to form the epitympanic recess to accommodate the ossicles of the middle ear.
- 1.1 A small piece of calcified material forming part of the skeleton of an invertebrate animal such as an echinoderm.
Example sentencesExamples - The position of these plates on the non-rudiment side of the larva suggests that ossicles occurring on the aboral surface are extraxial.
- The calcitic ossicles of crinoids, as is typical of echinoderms, form an internal skeleton that provides support and protection.
- As they grow, asteroids add new ossicles and increase size of existing ossicles.
- Calcareous ossicles make up the internal skeleton.
- Most such particles are echinoderm stem ossicles, brachiopods, bryozoans or other corals.
Origin Late 16th century: from Latin ossiculum, diminutive of os 'bone'.
