3. The auditory ossicles transmit and amplify sound waves in the middle ear. In sequence, waves pass from: _ .

A) incus- malleus- stapes. B) malleus- stapes- incus. C) malleus- incus- stapes. D) incus- stapes- malleus

1. Which of the structures below report head acceleration to the central nervous system? A) maculae B) cristaeampullares C) vestibule D) semicircular canals

2. Which of the following structures in the inner ear is essential for maintaining static equilibrium? A) utricle B) saccule C) semicircular canals D) cochlea.

Solution

3. Tympanic membrane which is also known as eardrum is vibrated by sound wave then moves the malleus which is the nearest ossicle . From malleus the vibrateion then pass on to stapes via incus and then to the fenestra ovalis.

Thus the correct sequence is C i.e., malleus , incus and stapes.
