The malleus is the first bone in the ossicular chain, which is a series of three bones that transmit sound from the eardrum to the inner ear.
What is the malleus?
The malleus is also known as the hammer because of its hammer-shaped appearance.
Here are some additional facts about the malleus:
- The malleus is about 8 mm long.
- The malleus is attached to the eardrum by a ligament.
- The malleus is connected to the incus by a synovial joint.
- The malleus is a very important bone in the hearing process.
What is the function of the malleus?
The malleus’s function is to amplify sound waves and transmit them to the incus, the second bone in the ossicular chain. The malleus does this by attaching to the eardrum and vibrating when sound waves hit the eardrum. The vibrations of the malleus are then transmitted to the incus, which in turn transmits them to the stapes, the third bone in the ossicular chain.
Is the hammer and malleus the same?
The hammer and malleus are not the same. The hammer is a bone in the middle ear, while the malleus is a bone in the ossicular chain. The hammer is the first bone in the ossicular chain, while the malleus is the second bone in the ossicular chain.
Where is the malleus present?
The malleus is present in the middle ear. The middle ear is located between the outer ear and the inner ear. The middle ear contains three bones: the malleus, the incus, and the stapes.
