Fig. 12 Transmission electron micrograph showing the Golgi complex (G), a distinctive assembly of cisternae and vacuoles, amid the tangle of conventional smooth endoplasmic reticulum (SER). A small coated vesicle (CV) is budding off a vacuole at the concave face (presumably the trans-face) of the Golgi. A lysosome (Ly), with granular content, a lipofuscin granule (Lf) with dense osmiophilic content, and three mitochondria (M) lie in the adjacent cytoplasm (×24,000). (N, nucleus)
