A layer of fat body cells covers the region of the cuticle above the dorsal vessel and the incurrent ostia can be a vertical or horizontal slit in the wall of the heart. One organized structure as a network ofalary muscles was observed holding the heart at its middorsal position and supporting the pericardial cells too. A great number of pericardial cells were found laterally associated with the heart and cellular projections from those cells insert directly into the heart wall.551-556engAntsCamponotusDorsal vesselHistologyUltramorphologyArtigoWOS:000170759700022Acesso restrito2-s2.0-00355382134396826019535898
