Rod Granules
The spherical rod granules are much the more numerous, and are placed at different levels throughout the layer.
Their nuclei present a peculiar cross-striped appearance, and prolonged from either extremity of each cell is a fine process; the outer process is continuous with a single rod of the layer of rods and cones; the inner ends in the outer plexiform layer in an enlarged extremity, and is imbedded in the tuft into which the outer processes of the rod bipolar cells break up.
In its course it presents numerous varicosities.

Famous quotes containing the word rod:
“Alas,
For the tireless heart within the little
Lady with rod that made them rise
From their noon apple-dreams, and scuttle
Goose-fashion under the skies!”
—John Crowe Ransom (1888–1974)
