What is the Henle fiber layer described as?

• A. A layer that contains photoreceptor nuclei
• B. A bridge transferring visual information to other cells
• C. A membrane separating inner segments from nuclei
• D. The inner limiting membrane

Answer: (B)

The Henle fiber layer is made up of the axons of photoreceptors that run obliquely from the outer nuclear layer toward the outer plexiform layer, especially in the macula around the fovea. This arrangement creates a radial bundle that physically connects the photoreceptors to the deeper retinal neurons. Because these photoreceptor axons carry signals toward bipolar and horizontal cells in the outer plexiform layer, the layer functions as a pathway that transfers visual information to other retinal neurons. It’s not the layer with photoreceptor nuclei (that’s the outer nuclear layer), not a membrane separating inner segments from nuclei (that’s the external limiting membrane), and not the inner limiting membrane (the boundary with the vitreous).
