MeSH Stapes

The stapes or stirrup is the stirrup-shaped small bone or ossicle in the middle ear which attaches the incus to the fenestra ovalis, the "oval window" which is adjacent to the vestibule of the inner ear. The malleus or hammer is a hammer-shaped small Bone or ossicle of the Middle ear which connects with the Incus and is attached The tensor tympani, the larger of the two muscles of the Tympanic cavity, is contained in the bony canal above the osseous portion of the Auditory tube, from which For the record label see Incus Records. The incus or anvil is the Anvil -shaped small Bone or ossicle The stapedius is the smallest striated muscle in the Human body For more uses of the word labyrinth, see Labyrinth (disambiguation The labyrinth is a System of fluid passages in the The ear canal ( external auditory meatus, external acoustic meatus) is a tube running from the Outer ear to the Middle ear. The tympanic membrane (also tympanum or myrinx is a thin membrane that separates the External ear from the Middle ear. The Eustachian tube (or auditory tube) is a tube that links the Pharynx to the Middle ear.

The stapes transmits the sound vibrations from the incus to the membrane of the inner ear inside the fenestra ovalis. For the record label see Incus Records. The incus or anvil is the Anvil -shaped small Bone or ossicle The oval window (or vestibular window) is a membrane-covered opening which leads from the Middle ear to the vestibule of the inner Ear. The stapes is also stabilized by the stapedius muscle, which is innervated by the facial nerve. The stapedius is the smallest striated muscle in the Human body The facial nerve is the seventh (VII of twelve paired Cranial nerves. [2]

In non-mammalian vertebrates, the bone homologous to the stapes is usually called the columella; however, in reptiles, either term may be used. Vertebrates are members of the Subphylum Vertebrata, Chordates with backbones or spinal columns The grouping sometimes includes In Evolutionary biology, homology has come to mean any similarity between characters that is due to their shared ancestry. Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers
