intermediate labellar taste bristle
ID: FBbt_00007412
Labellar bristle that is approximately 25 micrometers long (Shanbhag et al., 2001. These taste bristles house the sensory dendrites of 2 gustatory receptor neurons (Shanbhag et al., 2001, one sensitive to sugars and low concentrations of salt and the other to bitter and high salt concentrations (Hiroi et al., 2004; Jaeger et al., 2018, and one mechanosensory neuron (Shanbhag et al., 2001. (Hiroi et al., 2004, Shanbhag et al., 2001, Jaeger et al., 2018)
Shanbhag et al., 2001 and Hiroi et al. (2002) claim there are between 9 and 10 I-type sensilla present. Number, position and identity (short v intermediate) of individual sensilla seems to vary between animals (Shanbhag et al., 2001; Hiroi et al., 2002; Weiss et al., 2011; Jaeger et al., 2018. May infrequently also house a glutamatergic ppk23 neuron (Jaeger et al., 2018.
