Name: photoreceptor outer segment layer
Synonyms: photoreceptor outer segment layers
Definition: Layer of the retina composed of the outer segments of the photoreceptor cells. The photoreceptor outer segment is a specialized primary cilium consisting of a microtubule-based axoneme and regular stacks of membrane folds or disks containing the photopigments (opsins) required for the phototransduction cascade.

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.
