Term: Middle Ear
Definition (Myers):the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea's oval window. 1
Definition (alternative): the portion of the ear internal to the eardrum, and external to the oval window of the cochlea. 2
Contextual explanation: The middle ear includes three ossicles, which are very small bones, that are located right after the eardrum. The three ossicles are specifically called hammer, anvil, and stirrup. Their roles is to transfer the vibration of the eardrum into waves to pass on to the inner ear, where the cochlea is.
