0 a long, thin pole made of wood or metal:
The concrete is strengthened with steel rods.
1 a type of cell in the retina (= part at the back of the eye) that helps you to see when there is not much light
For nocturnal or deep-sea animals, the sensitivity afforded by achromatic rod vision may outweigh the benefits of cone-based color constancy.
Thus, we can conclude with confidence that rod cells do not contain a circadian oscillator.
Synaptic transmission mediated by internal calcium stores in rod photoreceptors.
The regulatory elements are able to direct expression to a subpopulation of cones while excluding expression in rods and non-photoreceptor retinal cells.
Increase in retinal area, density of rod nuclei, and densities of rod inner and outer segments were also studied in these and additional species.
Furthermore, two different patterns of distribution of rod precursors were distinguished.
Topography of cones and rods in the tree shrew retina.
The high density of rods (104,100 cells/mm2) with elongated outer segments (up to 30.5 6 2.9 m in length) indicates a light-sensitive retina.
