Rods are absent in the fovea: true or false?
Understand the Problem
The question is asking whether rods are absent in the fovea, which relates to the anatomy of the eye. The fovea is a small pit in the retina where visual acuity is highest, and this question addresses the specific types of photoreceptor cells present in that area.
Answer
True
The final answer is true.
Answer for screen readers
The final answer is true.
More Information
The fovea, particularly the foveola, is specialized for high acuity vision and contains only cone photoreceptors. Rod photoreceptors, which are more suited for low light conditions, are absent in this region.
