Notes on Meaning

The word "ossicle" is almost exclusively used in anatomical and biological contexts. Its primary and most common meaning is the set of bones in the middle ear. In zoology or paleontology, it can refer to other small bony or calcified structures in various animals, such as the ossicles in a starfish's body wall. However, without a specific modifier, it is generally understood to refer to the ear bones in humans and other mammals.
