Which retina layer contains retinal ganglion cells?

Which retina layer contains retinal ganglion cells?

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

Answer: (C)

The question is about where retinal ganglion cell bodies are located in the retina. The retina is organized into several layers, and the cell bodies of the retinal ganglion cells sit in the ganglion cell layer, which is the innermost layer near the vitreous. These ganglion cells receive input from bipolar and amacrine cells (via the inner plexiform layer) and then send their axons out of the eye to form the optic nerve. Other layers have different roles or constituents: the outer nuclear layer holds the nuclei of photoreceptors, the inner nuclear layer contains the cell bodies of bipolar, horizontal, and amacrine cells, and the plexiform layers are synaptic zones where these neurons connect but do not contain the ganglion cell bodies themselves.
