Figure 1. The photoreceptor CC.
(A) The photoreceptors are the most posterior cells in the neural retina at the back of the eye. (B) Rod photoreceptor cells are distributed across 4 layers of the retina. (C) The CC links the outer segment to the inner segment. The dashed link shows the portion of the CC in the cross-sectional view. The dimensions of the CC are approximately 1100 nm by 300 nm. OS, outer segment; IS, inner segment; ONL, outer nuclear layer; OPL, outer plexiform layer; CC, connecting cilium; BB, basal body; TF, transition fibers; MT, microtubule doublets.
