30 lip 2024 · There are three tiny articulating bones in the middle ear known as ossicles (from lateral to medial): malleus; incus; stapes; Their role is to mechanically amplify the vibrations of the tympanic membrane and transmit them to the cochlea where they can be interpreted as sound.
5 lip 2023 · The ossicles are situated in the middle ear and suspended by ligaments. They articulate with each other through synovial joints to form a chain across the length of the middle ear from the tympanic membrane (laterally) to the vestibular window (medially).
The ossicles (also called auditory ossicles) are three bones in either middle ear that are among the smallest bones in the human body. They serve to transmit sound vibrations sent from the ear drum to the fluid-filled labyrinth ( cochlea ).
The auditory ossicles are the three smallest bones in the human body, the malleus, the incus and the stapes. The first is attached to the tympanic membrane, the last to the circumference of the fenestra vestibuli, the incus being placed between and connected to both by delicate articulations.
