| Name: | retinal rod cell |
|---|---|
| Synonyms: | retinal rod cells |
| Definition: | 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 cones, but rod mediated vision has less spatial and temporal resolution than cone vision. |

| Name: | photoreceptor disc membrane |
|---|---|
| Synonyms: | |
| Definition: | Stack of disc membranes located inside a photoreceptor outer segment, and containing densely packed molecules of photoreceptor proteins that traverse the lipid bilayer. Disc membranes arise as evaginations of the ciliary membrane during the development of the outer segment and may or may not remain contiguous with the ciliary membrane. |
