The eye is formed during embryonic development by a combination of head ectoderm and neural tube tissue, the latter forming the retina.Thus, the retina is not a peripheral sensory organ ... but rather it is an outgrowth of the central nervous tissue. Because of this origin, the retina ...he eye is formed during embryonic development by a combination of head ectoderm and neural tube tissue, the latter forming the retina.

The retina is the photo receptive sensory layer of the back of the eye, where the optics of the eye focuses an image of what is in front of the eye. The optic nerve carries signals from the retina to the brain, which interprets them as visual images.The retina has two types of cells the rods and cones.he innermost light-sensitive membrane covering the back wall of the eyeball; it is continuous with the optic nerve 6 layers of cells that line the back of the eyeball.   â¦ One layer is sensitive to light and is the first step in turning light into vision.    These cells are a part of your brain.
