Which retina layer contains bipolar cells?

Which retina layer contains bipolar cells?

• A. Plexiform Layer
• B. Inner Nuclear Layer
• C. Ganglion Cell Layer
• D. Outer Nuclear Layer

Answer: (B)

Bipolar cells are the interneurons that link photoreceptors to ganglion cells, and their cell bodies are located in the inner nuclear layer of the retina. From this layer, their dendrites receive input from the photoreceptors via the outer plexiform layer, and their axons project to the inner plexiform layer to synapse with ganglion cells (and some amacrine cells). Other retinal layers have different roles: the outer nuclear layer houses photoreceptor cell bodies, the ganglion cell layer contains the cell bodies of retinal ganglion cells, and the plexiform layers are the synaptic contact zones rather than neuronal cell bodies. So, the layer that contains bipolar cells is the inner nuclear layer.
