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 press to its tendency to transform into diamond. The DIA multi-anvil is the main alternative to the Kawai cell: it uses six anvils to compress a cubic sample. In principle, the multi-anvil press is similar in design to a machine press except that it uses force magnification to amplify pressure by reducing the area over which force is applied: This is analogous to the mechanical advantage utilized by a lever, except the force is applied linearly, instead of angularly. For example, a typical multi-anvil could apply 9,806,650 N (equivalent to a load of 1000 t) onto a 10 mm octahedral assembly,
