Rod cell
Rod cell Cross section of the retina. Rods are visible at far right. Details Location Retina Shape Rod-shaped Function Low-light photoreceptor Neurotransmitter Glutamate Presynaptic connections None Postsynaptic connections Bipolar cells and horizontal cells Identifiers NeuroLex ID nlx_cell_100212 TH H3.11.08.3.01030 Anatomical terms of neuroanatomy [edit on Wikidata] Rod cells are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor, cone cells. Rods are usually found concentrated at the outer edges of the retina and are used in peripheral vision. On average, there are approximately 92 million rod cells in the human retina. [1] Rod cells are more sensitive than cone cells and are almost entirely responsible for night vision. However, rods have little role in color vision, which is the main reason why colors are much less apparent in dim light, and not at al...
