Eye Anatomy Quiz

Eye Anatomy

• The eyeball is approximately 2.5 cm in diameter.
• The fibrous tunic is composed of the sclera and cornea.
• The vascular tunic is composed of the choroid, ciliary body, and iris.
• The retina is the innermost layer of the eye.
• The choroid is the middle layer of the eye.
• The optic nerve carries visual information to the brain.
• The lens is a biconvex structure that focuses light onto the retina.
• The pupil is the opening in the center of the iris that controls the amount of light entering the eye.
• The iris regulates the size of the pupil.
• The ciliary body adjusts the shape of the lens for near or far vision.
• Light enters the eye through the cornea and pupil.
• The lens focuses the light onto the retina, where specialized cells convert the light into nerve signals.
• The optic nerve transmits these signals to the brain.
• Light from the pupil passes through the cornea to the lens.
• The lens focuses the light.
• The light is focused on the retina which converts the light into nerve signals.
• The optic nerve carries the nerve signals to the brain.
