Which of the following is NOT a bone of the middle ear?
A
Malleus
B
Mandible
C
Incus
D
Stapes
Verified step by step guidance1
Step 1: Begin by identifying the bones of the middle ear. The middle ear contains three small bones collectively known as the auditory ossicles: the malleus, incus, and stapes. These bones are essential for transmitting sound vibrations from the eardrum to the inner ear.
Step 2: Understand the function and location of the mandible. The mandible is the lower jawbone and is part of the facial skeleton, not the middle ear. It plays a role in chewing and forming the lower part of the jaw, but it is unrelated to hearing or the auditory ossicles.
Step 3: Compare the listed options to the bones of the middle ear. The malleus, incus, and stapes are all part of the middle ear, while the mandible is not.
Step 4: Recognize that the question is asking for the bone that is NOT part of the middle ear. Based on the comparison, the mandible is the correct answer because it is not one of the auditory ossicles.
Step 5: Conclude that the mandible is the correct choice as it is not anatomically or functionally related to the middle ear, unlike the malleus, incus, and stapes.
