Photoreceptors are located in which retinal region?

Explanation:
Photoreceptors—the rods and cones that detect light—sit in the outer part of the retina, closest to the back of the eye. Their light-sensing outer segments extend toward the retinal pigment epithelium, while the cell bodies reside in the outer nuclear layer. This location places them farthest from the inner limiting membrane and ahead of the choroid, which is why the outer retina near the back of the eye is their proper region. The inner limiting membrane is the retina’s inner boundary, the ganglion cell layer houses ganglion cell bodies, and the choroid lies behind the retina, not where the photoreceptors reside.
