What does the malleus articulate with?
What does the malleus articulate with?
The malleus (Latin: “hammer”) articulates with the incus through the incudomalleolar joint and is attached to the tympanic membrane (eardrum), from which vibrational sound pressure motion is passed. The incus (Latin: “anvil”) is connected to both the other bones.
What two structures does the malleus connect?
The middle ear contains three tiny bones: Hammer (malleus) — attached to the eardrum. Anvil (incus) — in the middle of the chain of bones.
What is the malleus made of?
The malleus (“hammer”), incus (“anvil”), and stapes (“stirrup”) are the three bones, also known as ossicles, of the inner ear. The malleus is the largest and the outermost of the bones, which are part of the auditory system. Together, the three bones make up an area no larger than the seed of an orange.
What joins the malleus incus and stapes?
The middle ear is made of the malleus, incus, and stapes and their two connecting muscles, the tensor tympani and stapedius.
Where does the malleus attach to the tympanic membrane?
The malleus is attached to and partly embedded in the fibrous layer of the inner surface of the tympanic membrane.
Which part of the malleus is attached to the tympanic membrane?
The malleus consists of a handle and a head. The handle is firmly attached to the tympanic membrane from the centre (umbo) to the upper margin.
How is malleus attached to eardrum?
What type of bone is the malleus?
The malleus, or hammer, is a hammer-shaped small bone or ossicle of the middle ear. It connects with the incus, and is attached to the inner surface of the eardrum. The word is Latin for ‘hammer’ or ‘mallet’….

What is an malleus?
: the outermost of a chain of three small bones of the mammalian middle ear. — called also hammer. — see ear illustration.
Where is the malleus attached?
tympanic membrane
The malleus is attached to and partly embedded in the fibrous layer of the inner surface of the tympanic membrane.
What is the stapes attached to?
oval window
The Cochlea The stapes, which is the smallest bone in the human body, is also the last of the three auditory ossicles. It is connected to the oval window, and drives the fluid in the cochlea, producing a traveling wave along the basilar membrane.
What is handle of malleus?
Description. The manubrium mallei (handle) is connected by its lateral margin with the tympanic membrane. It is directed downward, medialward, and backward; it decreases in size toward its free end, which is curved slightly forward, and flattened transversely.
