Answer 1

The region of the vertebrate eye, where the optic nerve passes out of the retina, is called as the blind spot. The blind spot is the part where the optic nerve passes out of the retina. Photoreceptors are absent from this region. the optic nerve is the nerve which carries the impulse from the photoreceptors to the optic lobes of the brain.

Optic chaisma is the place where the optic lobes overlap.

Iris is the part of the eye which regulates the size of the eye and controls the amount of light.

The fovea is the is the point where there are a maximum number of cone cells.
