Final answer:

The 'area of the retina found far out in the periphery' would NOT be considered part of the fovea, as the fovea consists of a cluster of cones responsible for sharp central vision, not the rods of the peripheral retina that help with low-light vision.

Step-by-step explanation:

The part of the fovea that would NOT be considered part of its structure is 'the area of the retina found far out in the periphery'. The fovea is primarily made up of a cluster of cones in the center of the retina, and it is specifically associated with high visual acuity, allowing us to see fine details clearly when we focus an image on it. The fovea is not located in the peripheral areas of the retina where rods are denser; rods are photoreceptors that operate better in low light conditions and are more involved with our peripheral vision.

When the eyes orient to focus on an object in bright light conditions, the image of the object falls directly onto the fovea, facilitating the clearest vision. In contrast, in dim light or for peripheral vision, rods in the periphery of the retina are more effective. It's important to note that in the fovea, each cone is connected to a single Retinal Ganglion Cell (RGC), permitting high precision in visual transduction, a contrast to the peripheral areas where multiple photoreceptors may share one RGC.
