Questions and Answers

1.

A is pointing to what part of the eye?
- A.
  
  Cornea
- B.
  
  Optic Nerve
- C.
  
  Iris
- D.
  
  Pupil
- E.
  
  Sclera
Correct Answer
E. Sclera

Explanation
The sclera is the white, tough, outer layer of the eye that helps maintain its shape and protect the delicate inner structures. It covers most of the eyeball and is visible as the white part of the eye. A is pointing to the sclera in this question.

  Lens
- E.
  
  Cornea

Which part of the eye controls the amount of pressure within the eye?
- A.
  
  Pupil
- B.
  
  Iris
- C.
  
  Lens
- D.
  
  Cornea
- E.
  
  None of the above
Correct Answer
E. None of the above

Explanation
The part of the eye that controls the amount of pressure within the eye is the aqueous humor, which is produced by the ciliary body and drained through the trabecular meshwork and Schlemm's canal. The options provided (pupil, iris, lens, cornea) do not directly control intraocular pressure. The aqueous humor and its drainage system are responsible for maintaining intraocular pressure.

Which part of the eye protects the front of the eye?
- A.
  
  Optic nerve
- B.
  
  Sclera
- C.
  
  Iris
- D.
  
  Cornea
Correct Answer
D. Cornea

Explanation
The correct answer is cornea. The cornea is the transparent outermost layer of the eye that covers the iris, pupil, and anterior chamber. It acts as a protective barrier for the front of the eye, shielding it from dust, debris, and other potential harm. The sclera, on the other hand, is the white, tough, outer layer of the eye that covers most of its surface, providing structural support. While the sclera also contributes to the protection of the eye, it is not specifically responsible for protecting the front of the eye.

Which transparent structure forms the front part of the eye, allowing light to enter and play a crucial role in focusing the incoming light onto the retina?
- A.
  
  Lens
- B.
  
  Cornea
- C.
  
  Iris
- D.
  
  Retina
- E.
  
  Optic Nerve
Correct Answer
B. Cornea

Explanation
The cornea, is the transparent front part of the eye that facilitates light entry and focuses it onto the retina. It plays a pivotal role in vision clarity. The lens, Retina, and iris, are distinct eye structures with different functions in the visual process.

  Lens
- E.
  
  Retina
Correct Answer
D. Lens
