The ganglion cell layer (ganglionic layer) consists of a single layer of large ganglion cells, except in the macula lutea, where there are several strata. Image File history File links Gray881. ... Human eye cross-sectional view. ... Image File history File links Gray882. ... Elseviers logo. ... A ganglion cell (or sometimes called a gangliocyte) is a type of neuron located in the retina that receives visual information from photoreceptors via various intermediate cells such as bipolar cells, amacrine cells, and horizontal 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. Erlenmeyer flasks from the Argonne National Laboratory glassblowing shop. ... An axon or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neurons cell body or soma. ...


From the opposite end numerous dendrites extend into the inner plexiform layer, where they branch and form flattened arborizations at different levels.


The ganglion cells vary much in size, and the dendrites of the smaller ones as a rule arborize in the inner plexiform layer as soon as they enter it; while those of the larger cells ramify close to the inner nuclear layer. In biology, a dendrite is a slender, typically branched projection of a nerve cell, or neuron, which conducts the electrical stimulation received from other cells to the body or soma of the cell from which it projects. ...
