AP PSYCHOLOGY

Detailed explanation-1: -The ossicles are actually tiny bones-the smallest in the human body. The three bones are named after their shapes: the malleus (hammer), incus (anvil) and stapes (stirrup). The ossicles further amplify the sound. The tiny stapes bone attaches to the oval window that connects the middle ear to the inner ear.

Detailed explanation-2: -These bones are called the malleus, incus, and stapes. The bones in the middle ear amplify, or increase, the sound vibrations and send them to the cochlea, a snail-shaped structure filled with fluid, in the inner ear.

Detailed explanation-3: -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.

Detailed explanation-4: -structure of human inner ear The upper one is the oval window, which is closed by the footplate of the stapes. The lower one is the round window, which is covered by a thin membrane.

Detailed explanation-5: -The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles. The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).
