Ossicles deep): the malleus, incus, and stapes, terms that in Latin are translated as "the hammer, anvil, and stirrup". Studies have shown that ear bones in mammal embryos are attached to the dentary, which is part of the jaw. These are ossified portions of cartilage—called Meckel's cartilage—that are attached to the jaw. As the embryo develops, the cartilage hardens to form bone. Later in development, the bone structure breaks loose from the jaw and migrates to the inner ear area. The structure is known as the middle ear, and is made up of the stapes, incus, malleus, and tympanic membrane. These
Anvil Verdi, and Wagner for example. Commonly pairs of anvils tuned a third apart are used. In practice modern orchestras commonly substitute a steel bar or other suitable steel structure that is easier to tune than an actual anvil, although a visibly convincing anvil-shaped prop may be shown as desired. In "Das Rheingold" Wagner scored for nine little, six mid-sized, and three large anvils, but orchestras seldom can afford instrumentation on such a scale. Anvil An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another
