Figure 4

Whole mount preparations and schematic of the complex tibial organ in all three leg pairs. (ac) In all legs, the subgenual organ (SGO), intermediate organ (IO) and crista acustica homolog (CAH) are present. Viewed from anterior. Note the lack of pigmentation in the cuticle at the level of the sensory organs. (df) Drawings of the complex tibial organ and its innervation in serial organisation. Anterior perspective. The structure and innervation of sensory organs were highly similar in all three leg pairs. Innervating nerves and nerve branches are labelled for the foreleg. The accessory organ, which is also innervated by N5B2, has been omitted for clarity. For the hindleg T3, the nerve N5B2 is omitted. Abbreviations: CAH, crista acustica homolog; CS, campaniform sensilla; IO, intermediate organ; SGO, subgenual organ; T1, foreleg; T2, midleg, T3, hindleg. Scale = 100 µm.
