abdominal lateral pentascolopidial chordotonal organ lch5 [FBbt_00002831]

Pentascolopidial chordotonal organ located in the lateral sensory cluster of the embryonic/larval abdominal segment. Each of the five scolopidia that constitute the lch5 organ contains a sensory unit composed of a neuron and a scolopale cell, and two accessory cells between which the sensory unit is stretched: a cap cell at the dendritic side and a ligament cell at the axonal side of the neuron (Halachmi et al., 2016. The cap and the ligament cells of all five organs are anchored to the cuticle by two cap attachment cells and one ligament attachment cell (Halachmi et al., 2016. The neuron, scolopale, cap, ligament and cap attachment cells of each scolopidium are derived from a single ato-expressing precursor through four asymmetric cell divisions (Halachmi et al., 2016. (Halachmi et al., 2016, Campos-Ortega and Hartenstein, 1997)
