Which of the following layers of the human eye contains the photoreceptors?Multiple choice question.ChoroidCorneaScleraRetina

Break Down the Problem

1. Identify the layers of the human eye listed in the multiple-choice options.
2. Determine which layer is responsible for containing photoreceptors (cells that detect light).

Relevant Concepts

• Photoreceptors: These are specialized cells in the retina that convert light into electrical signals. There are two main types: rods and cones.
• Layers of the Eye: The human eye consists of several layers, including the cornea, choroid, sclera, and retina.

Analysis and Detail

1. Choroid: This layer contains blood vessels but does not have photoreceptors.
2. Cornea: The outermost layer that provides most of the eye's optical power, but it does not contain photoreceptors.
3. Sclera: The white part of the eye, which provides protection and structure; it does not contain photoreceptors.
4. Retina: This is the inner layer at the back of the eye that contains photoreceptors (rods and cones) and is essential for vision.

Verify and Summarize

Reviewing the options shows that the retina is the only layer that contains photoreceptors. The other layers (choroid, cornea, and sclera) do not serve this function.

Final Answer

The correct answer is Retina.
