Ganglion layer

The ganglion layer ( English ganglion cell layer, GCL ) is one of ten layers of the vertebral retina , contains the bodies of ganglion cells and one type of amacrine cells .

Section of the retina (ganglion layer is indicated on the right, the third on top).
Retinal layers RPE - retinal pigment epithelium; OS - the outer segment of the photoreceptors ; IS - the inner segment of photoreceptors; ONL - outer nuclear layer; OPL - outer mesh layer; INL - inner nuclear layer; IPL - inner mesh layer; GC - ganglionic layer; BM - Bruch's membrane ; P - pigment epithelial cells; R - sticks; C - cones; Arrow and Puntkirn line - external boundary membrane H - horizontal cells; B - bipolar cells; M - Mueller cells ; A - amacrine cells; G - ganglion cells; AX - axons

The dendrites of the ganglion cells extend from the inner reticular layer , where they receive impulses from bipolar and amacrine cells. The axons of the ganglion cells are sent to the layer of nerve fibers , where they are collected in bundles and subsequently form the optic nerve , which carries several information processed by the retinal tissue into the central nervous system .

In addition to ganglion cells, this layer also contains another type of amacrine cells - displaced amacrine cells ( English displaced amacrine cells ) and neuroglia cells.

The number of cells of the ganglionic layer over the entire area is not constant; on the periphery of the retina, this layer contains one row of pericarions , and several layers in the central and middle parts. The layer thickness is about 20-30 microns.
