Question
Which of the following shows the correct labeling of the diagram shown below?
- Sclera, iris, pupil
- Cornea, pupil, iris
- Cornea, eye lens, pupil
- Sclera, eye lens, iris
Hint:
The colored part's centre is responsible for controlling the amount of light entering the eye. The colored part helps in the regulation.
The correct answer is: Sclera, iris, pupil
The correct option is a) Sclera, iris, pupil.
The sclera is the white outer covering of the eye. It is a tough fibrous tissue that extends from the cornea (the clear front part of the eye) to the optic nerve at the back of the eye. The sclera gives the eyeball its white color.
The pigmented tissue in the front of the eye that contains the pupil in the center. The iris controls the size of the pupil to increase or decrease the amount of light entering the eye. A round opening in the middle of the iris. The pupil changes size to allow light into the eye. It becomes smaller in bright places and becomes larger when the number of light decreases.
