Which layer contains the cell bodies of photoreceptors?

Explanation:
Photoreceptors—rods and cones—have their nuclei and cell bodies in the outer nuclear layer. This layer houses the photoreceptor cell bodies, while their inner and outer segments extend toward the outer retina to detect light. The outer plexiform layer, just next to it, is where their processes connect to bipolar and horizontal cells for signal transfer. In contrast, the inner nuclear layer contains the cell bodies of bipolar, horizontal, and amacrine cells, the ganglion cell layer holds the cell bodies of ganglion cells, and the inner plexiform layer is where these cells form synapses. So, the layer with the cell bodies of photoreceptors is the outer nuclear layer.
