Question
Which sequence correctly describes the flow of sound vibrations in the ear?a) Tympanic membrane → Malleus → Stapes → Incus → Cochleab) Tympanic membrane → Incus → Malleus → Stapes → Cochleac) Tympanic membrane → Malleus → Incus → Stapes → Cochlead) Tympanic membrane → Stapes → Incus → Malleus → Cochlea
Solution
The correct sequence that describes the flow of sound vibrations in the ear is:
c) Tympanic membrane → Malleus → Incus → Stapes → Cochlea
Here's the step-by-step process:
- Sound waves enter the ear canal and hit the tympanic membrane, or eardrum.
- The vibration of the eardrum causes the malleus (the first bone in the middle ear, also known as the hammer) to move.
- The malleus, in turn, moves the incus (the second bone, also known as the anvil).
- The incus then moves the stapes (the third bone, also known as the stirrup), which is the smallest bone in the human body.
- The movement of the stapes creates waves in the fluid of the cochlea (the spiral-shaped part of the inner ear), stimulating the hair cells inside it.
- These hair cells convert the vibrations into electrical signals, which are then sent to the brain via the auditory nerve. The brain interprets these signals as sound.
