| tympanic membrane |
(eardrum). A thin, translucent, elliptically-shaped and slightly concave membrane at the end of the meatus. The eardrum is made up of four layers. The outermost layer is continuous with the skin of the meatus, and the innermost layer is continuous with the mucous membrane of the middle ear. Of the two inner layers, the outer layer is composed of radial fibers, while the inner layer is composed of non-radial fibers. The tympanic membrane attaches to the malleus (hammer) of the middle ear. ...
