Middle ear bone. Coloured scanning electron micrograph (SEM) of the human middle ear, showing the stapes (ring-shaped). The stapes is one of three bones (known as the ossicles) in the middle ear that conduct sound waves from the outer ear to the inner ear. How intricate!
Of the inner, middle, and outer ear, the middle ear is connected to the Eustachian tubes. Any obstruction in these tubes hinders fluid drainage, thereby blocking the ears. Blocked ears cannot equalize pressure within your ears, and this leads to the ears feeling blocked
Incus and stapes (human middle ear bones). The incus transmits sound vibrations from the malleus to the stapes, which then transmits them to the inner ear. The middle ear bones are the smallest bones in the human body. SEM X45 - Richard Kessel
