Retinal ganglion cells project their axons across the inner surface of the retina towards the optic disk, where the optic nerve is formed.
WebD.W. Marshak, in Encyclopedia of Neuroscience, 2009 Introduction. Ganglion cells are the projection neurons of the vertebrate retina, conveying information from other retinal neurons to the rest of the brain. Their perikarya are the largest of any retinal neurons and are located along the inner margin of the retina, in the ganglion cell layer.
WebAs a part of the retina, bipolar cells exist between photoreceptors ( rod cells and cone cells) and ganglion cells. They act, directly or indirectly, to transmit signals from the photoreceptors to the ganglion cells. Structure [ edit] Bipolar cells are so-named as they have a central body from which two sets of processes arise. luxury beachfront rental homesWebApr 1, 2024 · Broadly retina consists of two primary layers: an inner neurosensory retina and retinal pigment epithelium (RPE). 1 Sensory retina develops from the inner layer of the neuroectoderm, whereas RPE is derived from the outer layer of the neuroectoderm. The RPE is continuous anteriorly with the pigment epithelium of the ciliary body. jeanny das fünfte mädchen ard mediathekThe front of the eye consists of the cornea, pupil, iris, and lens. The cornea is the transparent, external part of the eye. It covers the pupil and the iris and is the first location of light refraction. The pupil is the opening in the iris that allows light to enter the eye.
