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.
Endolymphatic system. The endolymphatic sac (ES) is a membranous structure in the inner ear located partly in the temporal bone and partly within the dura of the posterior fossa. It contains endolymph, which is similar in chemical makeup to intracellular fluid (high in K, low in Na).The endolymph in the ES is connected to that of other endolymphatic spaces of the inner ear via the endolymphatic duct (ED). The vestibular aqueduct contains both the ES and ED.ther named ducts in the endolymphatic system (blue on figure) include the cochlear duct (within the cochlea) ductus reuniens (between the saccule and cochlear duct), the utriculosaccular duct (between utricle and saccule).
