Retinal Rod (Noun)
Meaning
A visual receptor cell that is sensitive to dim light.
Classification
Nouns denoting body parts.
Examples
- The human eye contains millions of retinal rods that are sensitive to dim light and play a crucial role in peripheral and night vision.
- Retinal rods are specialized photoreceptor cells that are responsible for detecting low levels of light in the visual pathway.
- The retina of nocturnal animals typically contains a higher density of retinal rods than cones, allowing them to navigate in extremely low light conditions.
- Retinal rods are more numerous than cones in the human retina and are distributed throughout the peripheral areas of the visual field.
- In conditions of dim light, retinal rods are able to detect even the smallest amounts of light and send signals to the brain, allowing us to see in the dark.
