Rod cell - Wikipedia

Rod cells are photoreceptor cells in the retina of the eye that can function in lower light better 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 (vs ~6 million cones) in the human retina. [1]

Rod | Retinal Structure & Function | Britannica

Rod cells are much more sensitive to light than cones and are also much more numerous. The human eye contains about 130 million rods and about 7 million cones. Rod cells have an elongated structure and consist of four distinct regions: an outer segment, an inner segment, the cell body, and the synaptic region.

Photoreceptors (Rods & Cones): Anatomy & Function - Cleveland Clinic

Learn how rods and cones are specialized light-detecting cells in your eyes that convert light into nerve signals for your brain. Find out how they work, what conditions can affect them and how they relate to color vision.

Rods - American Academy of Ophthalmology

Rods are photoreceptor cells in the retina that help us see in low light and peripheral vision. Learn about eye problems that can affect rods, such as photokeratitis, retinitis pigmentosa and Usher syndrome.

Photoreceptors: Rods and cones - Kenhub

Rods. Rod cells have elongated cylindrical outer segments, resembling rods, with stacks of membrane-bound discs containing the photopigment rhodopsin.Rhodopsin contains two components: a form of the protein opsin, known as scotopsin and the chromophore, retinal.

Rods and Cones in Eye: Functions & Types of Photoreceptors - Vision Center

Learn about the two types of photoreceptors in the retina: rods and cones. Rods help with night vision and peripheral vision, while cones enable color vision and contrast perception.

Rod Cell - an overview | ScienceDirect Topics

Learn about rod cells, specialized neurons that detect individual photons of light and are involved in various retinal diseases. Find chapters and articles on rod cell structure, function, morphogenesis, and pathology from different sources.

Why rods and cones? | Eye - Nature

The synapse from the rod photoreceptor is reliably able to transmit the discrete quantal responses to the rod bipolar cell (RBC), as discovered from measurements of ERG b-wave sensitivity 12 and ...

Retina: Photoreceptors, Rods & Cones - Visual Function - Innerbody

Learn how rods and cones, the two types of photoreceptor cells in the retina, convert light into nerve signals for the brain. Rods are sensitive to low light and provide black-and-white vision, while cones are color-sensitive and respond to bright light.
