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.
Ontology: Anatomy Ontology [ZFA:0009275]
Name: rod photoreceptor outer segment
Synonyms:
Definition: The outer segment of a vertebrate rod photoreceptor that contains sealed membrane discs that are not connected to the ciliary membrane and containing rhodopsin photoreceptor proteins.

Name: decreased amount
Synonyms: decreased, decreased number, present in fewer numbers in organism, reduced, subnumerary
Definition: An amount which is relatively low.
