Figure 2 These transmission electron microscope (TEM) micrographs illustrate the main ultrastructural features of enterocytes, the absorptive cells of the ileum. Micrograph (A) shows the regular structure of microvilli (Mv) and the three components of junctional complex at the luminal end of the lateral plasma membrane, zonula occludens (ZO), zonula adherens (ZA) and macula adherens (MA); Micrograph (B) shows the disintegration of the zonula occludens and disordered structure of junctional complexes (arrows). The lipid droplets (L) and phagosomes (P) in the cytoplasm, rough endoplasmic reticulum (rER), swollen mitochondria (M) with ballooned cristae (Bc) and apical surface edema (asterisk) viewed; Micrograph (C) illustrates the regular structure of microvilli (Mv) and junctional complexes (ZO, ZA, MA).
