(From The ALA Glossary of Library and Information Science, 1983)Ear: The hearing and equilibrium system of the body. It consists of three parts: the EXTERNAL EAR, the MIDDLE EAR, and the INNER EAR. Sound waves are transmitted through this organ where vibration is transduced to nerve signals that pass through the ACOUSTIC NERVE to the CENTRAL NERVOUS SYSTEM. The inner ear also contains the vestibular organ that maintains equilibrium by transducing signals to the VESTIBULAR NERVE.Ear, Middle: The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.Waxes: A plastic substance deposited by insects or obtained from plants. Waxes are esters of various fatty acids with higher, usually monohydric alcohols. The wax of pharmacy is principally yellow wax (beeswax), the material of which honeycomb is made. It consists chiefly of cerotic acid and myricin and is used in making ointments, cerates, etc. (Dorland, 27th ed)Veterinary Service, Military: A corps of the armed services concerned with animal medicine, the chief interest of which is the care of government-owned working dogs (as in the military police units), working horses (as in state funerals), and working military dolphins (as in undersea exploration and other activities). In the United States Army Veterinary Corps animal medicine overlaps and interconnects with biomedical research using laboratory research animals. A related activity is laboratory animal care. The Corps provides limited care for privately owned animals of military personnel through non-appropriated funds. Military service veterinarians in the United States Army must be graduates of accredited veterinary schools and must have a state license. (Telephone communication with Lt. Col. William Inskeep II, U.S. Army Veterinary Corps, October 4, 1994)Dogs: The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE.

Ear auricles collect sound from the environment.Sound: A type of non-ionizing radiation in which energy is transmitted through solid, liquid, or gas as compression waves. Sound (acoustic or sonic) radiation with frequencies above the audible range is classified as ultrasonic. Sound radiation below the audible range is classified as infrasonic.
