General Information
Term RP neuron ID (Ontology) FBbt:00001451 (Fly Anatomy)
Definition Neuron of the embryonic/larval CNS. The RP neurons are mainly motor neurons. An RP motor neuron innervates each of muscles 2, 3, 6, 7, 11, 12, 13, 14, 19, 20, 28 and 30. RP2sib is the only RP neuron not to be a motor neuron.[ FlyBase:FBrf0047653 FlyBase:FBrf0064795 FlyBase:FBrf0112030 ]
Comment The "RP" name derives from the observation by Michael Bate and Corey Goodman that the large dorsal RP motoneurons are easily poked, and in that way reminded the two of "raw prawns", an Australian term of endearment.
