Fig. 11From: On springtails (Hexapoda: Collembola): a morphofunctional study of the jumping apparatusMorphological reconstruction of the lateral side of the 4th–6th abdominal segments, BP1, BP2 and BP3, the basal sclerites in Orchesella cincta and the insertion points of the musculature. A–C Furca extended; A External lateral view. B Internal lateral view. C Internal frontal view. D–F Furca flexed; D External lateral view; E Internal lateral view; F Internal frontal view. Dashed white line showing the border between BP1 and BP2 where there is strong deformation when the furca is flexed. BP1: basal plate 1; BP2: basal plate 2; BP3: basal plate 3; BS3: basal sclerite 3; M: manubriumBack to article page
