2. Matieus
3. Incub
4. Stapes
5. Oval window

a. 5, 4, 2, 3, 1
b. 1, 2, 3, 4, 5
c. 2, 4, 5, 1, 3
d. 3, 1, 4, 2, 5
e. 4, 5, 1, 2, 3

Answer 1

The correct sequence that traces the sound wave across the middle ear is: Tympanic membrane, Malleus, Incus, Stapes, Oval window.

Step-by-step explanation:

The correct sequence that traces the sound wave across the middle ear is: 1. Tympanic membrane, 2. Malleus, 3. Incus, 4. Stapes, 5. Oval window.

When a sound wave enters the ear, it causes the tympanic membrane to vibrate. This vibration is then amplified as it moves across the three small bones of the middle ear, namely the malleus, incus, and stapes. Finally, the amplified vibration is picked up by the oval window, which is the exterior boundary of the inner ear.
