Understanding the Smallest Bone in the Human Body

The video explains the smallest bone in the human body, the stapes, which is part of the inner ear bones known as auditory ossicles. It details how the malleus, incus, and stapes work together to transmit vibrations from the eardrum to the cochlea, which then sends signals to the brain for processing.

What is the smallest bone in the human body?

• Stapes

• Tibia

• Humerus

• Femur

Which bones are collectively known as the auditory ossicles?

• Femur, Tibia, Fibula

• Radius, Ulna, Humerus

• Malleus, Incus, Stapes

• Scapula, Clavicle, Sternum

What role does the malleus play in hearing?

• It filters out background noise

• It sends vibrations to the incus from the eardrum

• It amplifies sound waves

• It transmits sound directly to the brain

After receiving vibrations from the malleus, where does the incus send them?

• To the outer ear

• To the brain

• To the stapes

• To the cochlea

What is the final destination of the vibrations before they are processed by the brain?

• The malleus

• The incus

• The eardrum

• The cochlea
