AP PSYCHOLOGY

Detailed explanation-1: -The middle ear contains three tiny bones: Hammer (malleus)-attached to the eardrum. Anvil (incus)-in the middle of the chain of bones. Stirrup (stapes)-attached to the membrane-covered opening that connects the middle ear with the inner ear (oval window)

Detailed explanation-2: -The middle ear includes three small bones-the hammer (malleus), anvil (incus) and stirrup (stapes). The middle ear is separated from your external ear by the eardrum and connected to the back of your nose and throat by a narrow passageway called the eustachian tube.

Detailed explanation-3: -Joints link the malleus to the incus and incus to the stapes. All mammals have a soft connection between the incus and the stapes, which makes the stapes a semi-independent vibrating system (Fleischer, 1978). The malleus-incus articulation has a V-shape, the incus having the wedge and the malleus the notch.

Detailed explanation-4: -The major function of the hammer, anvil, and stirrup in the auditory system are to transmit vibrations from the eardrum, or tympanic membrane, to the oval window, which is also known as the fenestra ovalis. When sound hits the eardrum, it begins to vibrate.

Detailed explanation-5: -So from the options, only Pelvic bone Option (c) is not the one present in the middle ear.
