Identifier Name Description
FBbt:00004225 photoreceptor cell R7 Inner photoreceptor cell of the ommatidium whose centrally located rhabdomere extends across the distal two thirds (approximately) of each ommatidium. Each has a single axon that extends through a single lamina optic cartridge without making synapses. This axon crosses the first optic chiasm and extends through a single column of the medulla where it makes pre-synaptic contacts, mainly with medulla layers M1 and M5 (Takemura et al., 2008) before terminating in M6. It also receives synaptic input from photoreceptor cell R8 (Takemura et al., 2008), mostly in M3, and is presynaptic to Dm8a (in M6) and Tm5a (Gao et al., 2008).
