Which type of hearing loss is noise-induced?
- Correct Answer: sensorineural
  Explanation: Noise-induced hearing loss is caused by damage to the hair cells in the cochlea (inner ear), which affects the sensory or neural pathway.
Which term describes the turning outward of an eyelid?
- Correct Answer: ectropion
  Explanation: Ectropion is the outward turning of the eyelid, exposing the inner eyelid. Entropion is the inward turning of the eyelid.
Which term describes the ability of the lens to bend light rays?
- Correct Answer: refraction
  Explanation: Refraction is the bending of light as it passes through the lens, enabling focus on the retina. Accommodation refers to the lens’s ability to change shape to focus on objects at different distances.
Which condition is characterized by increased pressure within the eye?
- Correct Answer: glaucoma
  Explanation: Glaucoma results from increased intraocular pressure, which can damage the optic nerve. Cataracts involve clouding of the lens.
Which portion of the ear contains the sensory receptors for hearing and balance?
- Correct Answer: inner ear
  Explanation: The inner ear contains the cochlea for hearing and the vestibular apparatus for balance.
Which term describes the hearing loss associated with aging?
- Correct Answer: presbycusis
  Explanation: Presbycusis is age-related hearing loss, while presbyopia refers to the age-related decline in near vision.
Which term describes the flow of pus from the ear?
- Correct Answer: otopyorrhea
  Explanation: “Oto-” refers to the ear, and “-pyorrhea” refers to the flow of pus. Otorrhagia refers to bleeding from the ear.
Which portion of the eye contains vitreous humor?
- Correct Answer: posterior segment
