General Information
Term femoral chordotonal claw neuron ID (Ontology) FBbt:00049557 (Fly Anatomy)
Definition Femoral chordotonal organ (FeCO) neuron with a projection that splits into three branches upon entering the ventral nerve cord, giving it a claw-like morphology (Phillis et al., 1996; Mamiya et al., 2018). One branch follows the direction of the club neurons medially, another projects dorsally and another anteriorly (Mamiya et al., 2018). Its soma is found in a characteristic blade-shaped strip along the long axis of the femur (Mamiya et al., 2018). It encodes sensory information about tibial position (Agrawal et al., 2020).[ FlyBase:FBrf0090742 FlyBase:FBrf0240598 FlyBase:FBrf0247582 ]
Also Known As "FeCO claw neuron"
