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
Ear mite is squeezed into the ear canal and massaged at the base of the ear to distribute the medication. Selamectin is available as a once-a-month preparation that can be applied to the animal's skin, which prevents mite infestation over that time. Ear mites spread rapidly, and can be transmitted from even brief physical contact with other animals. In pets, ear mites most commonly affect cats, ferrets, and to a lesser extent dogs. Humans can rarely be infected with ear mites.<ref>https://www.youtube.com/watch?v=Z7CLzqMCmqE Ear mite Ear mites are mites that live in the ears of animals and humans.
