The stapes (Latin: "stirrup") articulates with the incus through the incudostapedial joint and is attached to the membrane of the fenestra ovalis, the elliptical or oval window or opening between the middle ear and the vestibule of the inner ear. As the stapes footplate moves into the oval window, the round window membrane moves out, and this allows movement of the fluid within the cochlea, leading to movement of the cochlear inner hair cells and thus hearing. . a. is also called the manubrium b. attaches to the round window by means of tiny ligaments . Rehabilitation. Further mechanical advantage is provided by the relative areas of the tympanic membrane and the foot plate of the stapes: the tympanic membrane has about 20 times the area of the stapes (Geisler, 1998).

The malleus ("hammer"), incus ("anvil"), and stapes ("stirrup") are the three bones, also known as ossicles, of the inner ear. tympanic membrane, also called eardrum, thin layer of tissue in the human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles, which are tiny bones in the tympanic (middle-ear) cavity. they mechanically transmit sound vibrations from the tympanic membrane, to which the malleus is attached, through the incus to the stapes, which attaches to a thin membrane covering a small opening, the oval window, that marks the beginning of the inner ear malleus (hammer) Incus (anvil) Stapes (stirrup) . The membrane lies across the end of the external canal and . murdermemetcalf . Incus is an anvil-shaped bone, present between the malleus and stapes. which are attached to a gelatinous membrane called the tectorial membrane. The malleus attaches to the tympanic membrane, and the stapes attaches to the oval window. The three ossicles are the malleus, incus, and stapes, which are Latin names that roughly translate to hammer, anvil, and stirrup. (1) A fluid-pressure difference across the BM, resulting from an inward stapes movement, causes it to move up (purple arrow). It is the most inferior of the laryngeal cartilages and attaches to the . collects sound waves and channels them inward; consists of the auricle, external auditory canal, and eardrum external auditory canal is a curved tube about 2.5 cm (1 in.) the___ is the bone of the middle ear directly attached to the tympanic membrane. The smallest bones in the body, the auditory ossicles, are three bones in each middle ear that work together to transmit soundwaves to the inner ear —thereby playing an essential role in hearing. incus (or anvil) - the bridge bone between the malleus and the stapes.
