Definition of Equivalent Decimals. Decimalsâ¦sometimes, they can be a little confusing. How can we tell if two decimals are equivalent, even if they appear differently on the page? How can the lowly zero aid in the detection of equivalent decimals? Well, if you stick with me, you'll have found the answers to these questions and mastered equivalent decimals by the end of this lesson!
The ossicles (also called auditory ossicles) are three bones in either middle ear that are among the smallest bones in the human body. They serve to transmit sounds from the air to the fluid-filled labyrinth (cochlea). The absence of the auditory ossicles would constitute a moderate-to-severe hearing loss. The term ossicle literally means tiny bone and, though the term may refer to any small bone throughout the body, it typically refers to the malleus, incus, and stapes (hammer, anvil, and stirrup) of the middle ear.
The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow, air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bonesâthe malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.
