2023年8月8日 · The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture.
Nonvisual retina - e-Anatomy - IMAIOS
The nonvisual retina is its portion non sensitive to the light, divided into two zones: The ciliary part of retina : located on the posterior face of the ciliary body (composed of a simple layer of pigmented cuboidal epithelium)

2005年5月1日 · A radial section of a portion of the retina reveals that the ganglion cells (the output neurons of the retina) lie innermost in the retina closest to the lens and front of the eye, and the photosensors (the rods and cones) lie outermost in the retina against the …
Retina - Wikipedia
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.
Retina of the Eye: What It Is, Function & Anatomy - Cleveland Clinic
The retina is a key bridge between the light that enters your eyes and the images you see. Special cells in your retina react to light and pass signals to your brain that let you see the world around you. Talk to your eye care specialist if you notice gradual vision changes.
Functional Architecture of the Retina: Development and Disease
Structure and function are highly correlated in the vertebrate retina, a sensory tissue that is organized into cell layers with microcircuits working in parallel and together to encode visual information.

2016年1月1日 · The most internal layer of the retina is the internal limiting membrane (layer 9). This layer is composed of the basal lamina of Muller cells. It is thickest in the posterior fundus and becomes thinner as one moves more anterior.
The Human Retina | Structure, Physiology & Development
The human retina is the innermost layer of the eyeball that detects light and converts light signals into an action potential. Anatomically, it is divided into two parts; the optic retina and the non-visual retina.
