Question 1 · 1 mark · Difficulty 2/3

A steelband musician from Trinidad noticed that after prolonged practice sessions at high volumes, he experienced temporary hearing loss. Which part of the ear is MOST likely to be damaged by exposure to loud sounds over time?

  1. Tympanic membrane
  2. Hair cells in the cochlea
  3. Semicircular canals
  4. Eustachian tube
Show answer & explanation
✓ Answer: BHair cells in the cochlea
Award 1 mark for selecting B. Prolonged exposure to loud sounds damages the delicate hair cells (sensory receptors) in the cochlea, leading to noise-induced hearing loss. A is incorrect because the tympanic membrane can rupture from sudden loud noises but is not the primary site of damage from prolonged exposure. C is incorrect because semicircular canals are involved in balance, not hearing. D is incorrect because the Eustachian tube equalizes pressure and does not detect sound.
Question 2 · 1 mark · Difficulty 2/3

A doctor examining a patient in St. Lucia diagnosed an infection of the middle ear. Which structure would MOST likely be inflamed in this condition?

  1. Cochlea
  2. Pinna
  3. Area surrounding the ossicles
  4. Semicircular canals
Show answer & explanation
✓ Answer: CArea surrounding the ossicles
Award 1 mark for selecting C. Middle ear infections (otitis media) affect the air-filled cavity containing the ossicles. A is incorrect because the cochlea is part of the inner ear. B is incorrect because the pinna is part of the outer ear. D is incorrect because semicircular canals are in the inner ear.
