Question

Quizplus · Accepted Answer

The outer segment of the photoreceptors is the "business end" containing the molecules for detecting light. It is embedded in the pigment epithelium, which is a layer of cells that support and nourish the photoreceptors. Therefore, choice B is the best answer. Choice A is incorrect because synapses occur between photoreceptors and bipolar cells in the inner nuclear layer. Choice C is incorrect because the outer nuclear layer contains the cell bodies of the photoreceptors.
