Retina amacrine cell

Amacrine cells ( amacrine: . From Greek a-, " not," "un - ," macros " large" and ís, iNOS gene " muscle ", " chord ", " fiber" ) are neurons in the retina of vertebrates. Their cell bodies are located mainly in the inner nuclear layer (INL ). With over 20 types they represent a very diverse class of neurons in the retina dar.

They interact synaptically in the inner plexiform layer ( IPL) with both the axons of the bipolar cells and the dendrites of retinal ganglion cells and thus provide - similar to the horizontal cells - for lateral connections within the retina, but on a second level. Forms of amacrine cells or modulate the current through the bipolar signal flow to the ganglion cells.

Your name received the amacrine cells, because they thought they had no axon (Santiago Ramón y Cajal, 1894). For most that actually counts is found on their dendrites both input and output synapses; an axon is missing. However, some 'large field ' amacrine cells have long axonähnliche extensions that serve to signal transmission over longer distances in the retina, but not emerge as the axons of the ganglion cells of the retina.
