Which layer contains the cell bodies of bipolar, horizontal, and amacrine cells?

• A. Inner Nuclear Layer (INL)
• B. Outer Nuclear Layer (ONL)
• C. Ganglion Cell Layer (GCL)
• D. Nerve Fiber Layer (NFL)

Answer: (A)

Cell bodies of bipolar, horizontal, and amacrine cells are located in the inner nuclear layer. This layer sits between the outer nuclear layer, which houses photoreceptor cell bodies, and the ganglion cell layer, which contains ganglion cell bodies. The inner nuclear layer is where these retinal interneurons reside, forming the processing hub that integrates signals before they pass onward to the ganglion cells. Bipolar cells relay information from photoreceptors to ganglion cells; horizontal and amacrine cells provide lateral, modulatory interactions within the retina. In contrast, the outer nuclear layer contains photoreceptor cell bodies, the ganglion cell layer contains the bodies of ganglion cells, and the nerve fiber layer consists of the axons of those ganglion cells heading toward the optic nerve.
