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 Peak have formed after Mount Cerberus. According to the Global Volcanism Program of the Smithsonian Institution, its formation occurred during the late Pleistocene epoch. It has not erupted in recent times; it is thought that its last activity was probably thousands of years ago. Anvil Peak has experienced deep erosion, more so than the other cones on the islands, which is partially due to its height.
