  • in cones, saccules are formed by infoldings of cell membrane, but in rods, disks are separated from cell membrane.

  • fovea contains no rods; each foveal cone has single midget bipolar cell connecting it to single ganglion cell (1 foveal cone → 1 fiber in optic nerve).

  • in extrafoveal retina, rods predominate, and there is good deal of convergence (flat bipolar cells make synaptic contact with several cones, and rod bipolar cells make synaptic contact with several rods).
