Figure 7. Müller cells are closely associated with, and interact with, all retinal neurons. The interactions among Müller cells and retinal neurons are vital to retinal homeostasis. Müller cells span nearly the entire thickness of the retina, from ILM at NFL to OLM at the junction of the inner and outer segments of PR. Neuronal somata and processes are ensheathed by the processes of Müller cells (one Müller cell is shaded pink at right). Chor, choroid; BrM, Bruch's membrane; RPE, retinal pigmented epithelium; PR, photoreceptor outer segments; OLM, outer limiting membrane; ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer; NFL, nerve fiber layer; ILM, inner limiting membrane; BV, blood vessel; r, R, rod photoreceptor cell; c, cone photoreceptor cell; H, horizontal cell; bc, B, bipolar cell; ac, A, amacrine cell; rgc, G, retinal ganglion cell; M, Müller cell; as, astrocyte.
