General Information
Term adult leg stretch receptor neuron ID (Ontology) FBbt:00048300 (Fly Anatomy)
Definition Mechanosensory neuron that has a dendrite at a leg joint and is activated by movement of the joint (Desai et al., 2014). There is one such neuron for each femur-tibia and tibia-tarsus joint in all legs (Desai et al., 2014), and one for the coxa-trochanter joint at least in the prothoracic leg (Kuan et al., 2020). Their dendritic tips are not associated with cuticular structures, scolopales or musculature (Desai et al., 2014). Close to its tip, the dendrite branches towards the lateral aspect of the joint; the cell body is found near these dendritic terminals. (Desai et al., 2014). Its axons terminate in the leg neuropil (Tsubouchi et al., 2017).[ FlyBase:FBrf0224410 FlyBase:FBrf0237124 FlyBase:FBrf0247324 ]
Also Known As"leg stretch receptor primary neuron" ; "Lsr1N"
