Basal cytoplasm of several digestive cells (dc) in millipedes. A. E. pulchripes. The cytoplasm is rich in mitochondria (m) and cisterns of the rough endoplasmic reticulum (RER) in the neighborhood of basal cell membrane folds (arrows). Basal lamina (bl), spherites (sp), spheres with reserve material (rm), fragments of regenerative cells (rc). Transverse section. TEM. Scale bar = 1.4 µm. B. U. transsilvanicus. Regenerative cells (rc), basal lamina (bl), cisterns of the rough endoplasmic reticulum (RER), nucleus (n), visceral muscles (vm), reserve material (rm), digestive cells (dc), mitochondria (m). Transverse section. TEM. Scale bar = 0.6 µm.
