General Information
Term adult sex peptide sensory neuron ID (Ontology) FBbt:00111303 (Fly Anatomy)
Definition Sensory neuron of the female reproductive tract that responds to sex peptide (Hasemeyer et al., 2009; Yang et al., 2009). There is one cell body of these cells on each lateral oviduct and 3 on either side of the uterus (Yang et al., 2009).[ FlyBase:FBrf0207501 FlyBase:FBrf0207523 FlyBase:FBrf0225544 ]
Also Known As "sex-peptide neuron" ; "SP sensing neuron" ; "SP-sensing neuron" (for all, see Synonyms field below)
Comment These neurons express both fruitless (FBgn0004652) and pickpocket (FBgn0020258) (Yang et al., 2009; Hasemeyer et al., 2009). Sex peptide receptor appears to be axonal, rather than dendritic (Yang et al., 2009).
