False.
Fill in the blank: The __________ is a layer that contains melanin to help absorb light.
choroid
What is the fovea centralis?

A) Sclera
True or False: The cornea is avascular.
True.
What is the primary purpose of the cornea?
To refract light entering the eye.
Fill in the blank: The __________ is the area where the optic nerve exits the eye.
optic disc
What is the significance of the macula?
It is responsible for central vision and color perception.
Multiple choice: Which of the following is NOT a function of the choroid? A) Nutrient supply B) Light absorption C) Vision processing
C) Vision processing
True or False: The retina is composed of multiple layers of neurons.
True.
What does the term ‘retinal detachment’ refer to?
A medical condition where the retina separates from the underlying choroid layer.
Fill in the blank: The __________ connects the eye to the brain.
optic nerve
What is the role of the ciliary body?
To control lens shape and produce aqueous humor.
