Which of the following is a layer containing neurons at the back of the eye?A) OrbitsB) ScleraC) PupilD) LensE) Retina

The correct answer is E) Retina.

Explanation

The retina is the layer at the back of the eye that contains photoreceptor cells (neurons) which detect light and send visual information to the brain. The other options do not refer to a layer containing neurons:

• A) Orbits: Refers to the bony cavities that house the eyes.
• B) Sclera: The white outer coating of the eyeball, not containing neurons.
• C) Pupil: The adjustable opening in the center of the iris that allows light to enter the eye.
• D) Lens: The transparent structure behind the pupil that helps focus light onto the retina, but it does not contain neurons.

Thus, the layer containing neurons at the back of the eye is the retina.
