| 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: | rod photoreceptor disc membrane |
|---|---|
| Synonyms: | |
| Definition: | Stack of disc membranes located inside a rod photoreceptor outer segment, and containing densely packed molecules of rhodopsin photoreceptor proteins that traverse the lipid bilayer. It is thought that rod disc membranes arise as evaginations of the ciliary membrane near the base of the outer segment, which then become completely separated from the ciliary membrane, during the development of the rod outer segment. |
