Which statement best describes the Henle fiber layer?

• A. It transmits signals from photoreceptors to the brain
• B. It stores the nuclei of photoreceptors
• C. It is the site of photoreceptor inner segments
• D. It contains the cell nuclei of photoreceptors

Answer: (D)

Henle fiber layer is the group of obliquely running photoreceptor axons in the macula, especially near the fovea. These fibers originate from the photoreceptor cell bodies located in the outer nuclear layer and travel toward the outer plexiform layer to reach their synapses with bipolar and horizontal cells. The nuclei of photoreceptors themselves reside in the outer nuclear layer, not in Henle’s fiber layer. So this layer isn’t about storing nuclei or inner segments; it’s about the axons of photoreceptors guiding signals toward the synaptic network. In short, Henle fiber layer consists of photoreceptor axons, not their nuclei.
