Photoreceptors concentrated in the periphery of the retina that are most active in dim illumination; rods do not produce sensation of color.

There are two types of receptor cells in the human eye; the cones and the rods. The rods are the receptors in the eye which detect movement. Rods are also used in night vision.

Long, slender structures within the retina that perceive faint light. Also, rod-shaped bacteria (bacilli).

A class of light-sensitive receptor cells (photoreceptors) in the retina that are most active at low levels of light. See Figure 10.2. Compare cones.

Drawrods beneath a frieght train.

One type of specialized light sensitive cells (photoreceptors) in the retina that provide side vision and the ability to see objects in dim light (night vision). Also, see cones.

Light-sensitive cells in the retina that respond best in darkness and dim light.

Photoreceptor cells in the retina of the eye that can function in low light levels, and which are primarily responsible for night vision.

Photosensitive Afferent Neurons located in the peripheral Retina, with density increases radially away from the Fovea Centralis. Being much more sensitive to Light than the Retinal Cone Cells, the rod [..]

A Plant genus of the Family Asteraceae known for allergenic Pollen (Allergens).

One of the two photoreceptor cell types of the vertebrate retina. In rods the photopigment is in stacks of membranous disks separate from the outer cell membrane. Rods are more sensitive to light than [..]
