Which anatomical structure corresponds with the physiological blind spot?

• A. Optic Nerve
• B. Fovea Centralis
• C. Optic Disc
• D. Macula

Answer: (C)

The physiological blind spot corresponds with the optic disc, which is the area on the retina where the optic nerve fibers exit the eye. This region lacks photosensitive cells (rods and cones), meaning that no visual information can be detected in this specific area. As a result, when an image falls on the optic disc, it cannot be perceived by the brain, creating a "blind spot" in the visual field. Understanding the anatomical features of the eye is crucial for grasping how vision works and where potential issues may arise. The optic nerve, while essential for transmitting visual information to the brain, is not responsible for the blind spot itself; instead, it is the point of exit for the nerve fibers that creates the gap in the retina. The fovea centralis and macula are parts of the retina known for high visual acuity due to their dense concentrations of photoreceptor cells, thus they do not relate to the concept of a blind spot.
