Exempel på hur man kan använda STAPES i en mening

• The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.
• Though the term may refer to any small bone throughout the body, it typically refers to the malleus, incus, and stapes (hammer, anvil, and stirrup) of the middle ear.
• The incus receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes medially.
• The stapes or stirrup is a bone in the middle ear of humans and other tetrapods which is involved in the conduction of sound vibrations to the inner ear.
• He gave the first distinct account of the true configuration of the sphenoid and the ethmoid bone as well as several other bones of the head, and has the merit of first describing (1546) the third ear bone, the stapes.
• As the lesions reach the stapes the bone is resorbed, then hardened (sclerotized), which limits its movement and results in hearing loss, tinnitus, vertigo or a combination of these.
• Computed tomography has revealed that Ichthyostega had a specialized ear, including a stapes with a unique morphology compared to other tetrapods or to any fish hyomandibula.
• Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis.
• The base of the stapes couples vibrations into the cochlea via the oval window, which vibrates the perilymph liquid (present throughout the inner ear) and causes the round window to bulb out as the oval window bulges in.
• Conductive hearing ability is mediated by the middle ear composed of the ossicles: the malleus, the incus, and the stapes.
• Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani (eardrum).
• These devices substitute the functions performed by the eardrum and stapes while simulating the frequency analysis performed in the cochlea.
• The stapedius emerges from a pinpoint foramen or opening in the apex of the pyramidal eminence (a hollow, cone-shaped prominence in the posterior wall of the tympanic cavity), and inserts into the neck of the stapes.
• At the end of the ossicular chain, movement of the stapes footplate within the oval window of the cochlea generates a pressure field within the cochlear fluids, imparting a pressure differential across the basilar membrane.
• The compression and rarefaction of these waves set this thin membrane in motion, causing sympathetic vibration through the middle ear bones (the ossicles: malleus, incus, and stapes), the basilar fluid in the cochlea, and the hairs within it, called stereocilia.
• The stapedial artery passes through the ring of the stapes and divides into supraorbital, infraorbital, and mandibula branches which follow the three divisions of the trigeminal nerve.
• If the round window were to be absent or rigidly fixed (as can happen in some congenital abnormalities), the stapes footplate would be pushing incompressible fluid against the unyielding walls of the cochlea.
• Characteristics of Balanerpeton woodi include the presence of large external nares, large interpterygoid vacuities (holes in the back of the palate), and an ear with a tympanic membrane and rod-like stapes.
• Multiple-component, multiple-frequency tympanometry is invaluable for the differential diagnosis of fixation of the lateral ossicular chain from fixation of the stapes, profound mixed hearing losses, clinical otosclerosis from disruption of the ossicular chain, hypermobility of the incudostapedial joint, and congenital ossicular fixation in children.
• The vibration of the tympanic membrane drives the middle ear ossicles, the malleus, incus, and stapes to vibrate in sync with the eardrum.
