Which layer is described as a bridge transferring visual information from photoreceptors to other processing cells?

• A. Henle fiber layer
• B. Outer Plexiform Layer
• C. External limiting Membrane
• D. Outer Nuclear Layer

Answer: (A)

The Henle fiber layer serves as the bridge carrying signals from photoreceptors toward the next neurons in the retina. In the macula, cone and rod axons run obliquely through this layer toward the outer plexiform layer, where their synapses with bipolar and horizontal cells occur. So, the Henle fiber layer is the structural conduit that channels visual information from the photoreceptors to the processing cells, making it the best descriptor of a bridging layer. The outer plexiform layer is where the actual synaptic transfer happens, while the external limiting membrane and outer nuclear layer do not form this bridging pathway.
