Middle ear ear and throat. The primary function of the middle ear is to efficiently transfer acoustic energy from compression waves in air to fluid–membrane waves within the cochlea. The middle ear contains three tiny bones known as the ossicles: "malleus", "incus", and "stapes". The ossicles were given their Latin names for their distinctive shapes; they are also referred to as the "hammer", "anvil", and "stirrup", respectively. The ossicles directly couple sound energy from the ear drum to the oval window of the cochlea. While the stapes is present in all tetrapods, the malleus and incus evolved from lower and upper jaw
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
