  2. Retina - Wikipedia

    en.wikipedia.org/wiki/Retina

    The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception.

  3. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    The optic radiations, one on each side of the brain, carry information from the thalamic lateral geniculate nucleus to layer 4 of the visual cortex. The P layer neurons of the LGN relay to V1 layer 4C β. The M layer neurons relay to V1 layer 4C α. The K layer neurons in the LGN relay to large neurons called blobs in layers 2 and 3 of V1. [26]

  4. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    Humans have two eyes, situated on the left and the right of the face. The eyes sit in bony cavities called the orbits, in the skull. There are six extraocular muscles that control eye movements. The front visible part of the eye is made up of the whitish sclera, a coloured iris, and the pupil. A thin layer called the conjunctiva sits

  5. Outer nuclear layer - Wikipedia

    en.wikipedia.org/wiki/Outer_nuclear_layer

    The outer nuclear layer (or layer of outer granules or external nuclear layer), is one of the layers of the vertebrate retina, the light-detecting portion of the eye.Like the inner nuclear layer, the outer nuclear layer contains several strata of oval nuclear bodies; they are of two kinds, viz.: rod and cone granules, so named on account of their being respectively connected with the rods and ...

  6. Globe (human eye) - Wikipedia

    en.wikipedia.org/wiki/Globe_(human_eye)

    The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [1]

  7. Eye development - Wikipedia

    en.wikipedia.org/wiki/Eye_development

    The inner layer of the optic cup is made of neuroepithelium (neural retina), while the outer layer is composed of retinal pigment epithelium (RPE). Experiments have determined that RPE cell differentiation and maintenance requires interaction with neighboring tissues, most likely canonical Wnt signaling, while neural retina differentiation is ...

  8. Ganglion cell layer - Wikipedia

    en.wikipedia.org/wiki/Ganglion_cell_layer

    In the anatomy of the eye, the ganglion cell layer (ganglionic layer) is a layer of the retina that consists of retinal ganglion cells and displaced amacrine cells. The cells are somewhat flask -shaped; the rounded internal surface of each resting on the stratum opticum , and sending off an axon which is prolonged into it.

  9. Outline of human anatomy - Wikipedia

    en.wikipedia.org/wiki/Outline_of_human_anatomy

    Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
