General Information
Term eye photoreceptor cell ID (Ontology) FBbt:00006009 (Fly Anatomy)
Definition Photoreceptor cell that forms the core of each ommatidium in the adult eye. Eight of these photoreceptors are arranged in each ommatidial core, bundled like the staves of a barrel. Each has a photosensitive rhabdomere that projects into the barrel cavity and adjacent supporting membrane, the stalk (Wolff and Ready, 1993). Each extends an axon into the optic lobe. Activation of the photoreceptor by light results in depolarization and in histamine release at the synapses of these axons (Sarthy, 1991).[ FlyBase:FBrf0054495 FlyBase:FBrf0064798 ]
Also Known As "lamina receptor cell" ; "retinula cell"
Comment Note - eyelet photoreceptors are NOT sub-types.
