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
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.
