| Term | sensillum of sacculus chamber II | ID (Ontology) | FBbt:00004183 (Fly Anatomy) | |||||
| Definition | Sensillum of chamber II of the sacculus of the antenna (Shanbhag et al., 1995). This sacculus chamber is divided into multiple compartments, each of which houses one of these sensilla in a pit (Shanbhag et al., 1995). It has a smooth cuticular surface, lacking pores, and a plugged pore-like structure at its distal tip (Shanbhag et al., 1995). It houses the sensory dendrites of three hygrosensory neurons, two expressing Ir40a and one expressing Ir68a (Shanbhag et al., 1995; Enjin et al., 2016; Marin et al., 2020).[ FlyBase:FBrf0084361 FlyBase:FBrf0232388 FlyBase:FBrf0246456 ] | |||||||
| Also Known As | "blunt-tipped sensillum of sacculus" ; "np-Sc" | |||||||
| Comment | Classified as coeloconic by Shanbhag et al. (1995), but morphologically dissimilar to 'coeloconic' sensilla of the antennal surface - which are not located in a pit (Shanbhag et al., 1999 - FBrf0084361). | |||||||
