What are the bones in the middle ear?

In the middle ear, there are three bones, commonly referred to as ossicles . Bone names come from Latin and are known as Malleus , Incus and Stapes . Their purpose is to increase the overall function of the middle ear and transmit the sound from the outer ear to the inner ear.

ossicles have a small size, the smallest bones in the human body, and the staps are the smallest. Their names reflect the distinctive shape and role of each bone. Their common names are a hammer, anvil and caliper, objects that each of them visibly resembles.

One end of the middle ear is associated with the tympanic membrane or to the ears and the other with the opening of the inner ear. This interconnected setting from the ear drum to the auditory osicilla into the inner ear allows sound waves that enter the outer ear, vibrate the liquid into the eardrum. This fluid is pushing the bones in the middle ear, which then spreads it to an oval victory, a membrane covering the entrance to the inner earFinally, into a part of the inner ear known as Kochle.

Special arrangement of three bones in the middle ear acts as a lever to facilitate sound guidance into the inner ear. The hammer moves the anvil and the anvil is pushing the stirrup. The hammer holds a part of the ear drum that can move in response to the intake of sound wool. The anvil is the middle piece, connected to the hammer at one end and the caliper at the end closer to the inner ear. Tluh is the last reference that pushes against the fluid in the inner ear for perception of sound.

hammer and stirrups are associated with two small muscles that initiate tympanic reflex, also known as an acoustic reflex that acts as a protective mechanism to prevent ear damage from harmful sounds. stapedius muscle resting the movement of the stirrup, damping of vibrations that could be too strong or high amplitude. tensor tympani muscleTimes are tightened by Osicles by pulling the hammer. This action creates an effect similar to stapedius on the yoke, so the vibrations are reduced, preventing loud sounds from the ear damage.
