Answer
The optic disk has no receptor cells.
Solution
1. The retina contains several regions responsible for converting light into neural signals.
2. The **optic disk** is the area where the optic nerve exits the eye and, consequently, contains no receptor cells.
3. This same region is also known as the **blind spot**, since the lack of receptor cells means no visual information is detected there.
Thus, the correct answer is **Optic disk**.

Did you know that the optic disk, also known as the blind spot, is the place on the retina where the optic nerve exits the eye? Because this area lacks photoreceptor cells, it cannot detect light, leading to a small blank spot in our field of vision. Thankfully, our brains cleverly fill in this gap, so we usually don't even notice it! In terms of real-world application, understanding the blind spot is crucial for safe driving. For instance, when changing lanes, it’s important to check your mirrors and turn your head to ensure you aren’t missing any vehicles lurking in that area. This knowledge can help prevent accidents and keep everyone safer on the road!
