WebWhat is a bipolar cell in anatomy? As a part of the retina, the bipolar cell exists 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. Bipolar cells are so-named as they have a central body from which two sets of processes arise. WebFeb 29, 2012 · Cone bipolar cells participate in transferring ON and OFF rod signals from distal retina to ganglion cells even without AII amacrine intermediation. This occurs through two pathways. In the first, signals …
