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 firing trail. The top anvil is placed upside down, face to face with the bottom anvil. Anvil firing was once commonly performed in the Southern United States as a substitute for fireworks during celebrations. One such noteworthy celebration was held on the day the state of Texas voted to secede from the Union. On February 23, 1861, Texas Ranger and prominent Union supporter, Thomas Lopton Campbell Jr., was held captive and forced to "fire the anvils" in the streets of Austin. Anvils were also traditionally fired on St. Clement's Day, honoring Pope Clement I, the patron saint of blacksmiths and metalworkers.
