Cell Structure III

Light Microscopy Slides : 146: lipofuscin pigment 252: Observe secretory droplets, mitochondria 270: Dark black granules of different staining intensities in macrophages   Electron Microscopy EM’s: 1: Shape of secretory droplets (compare with slide 252) 2: Nothing specified 2b: Cortical microfilaments, compare sizes, intermediate filaments (vimentin or keratin types) 4: Brush border, lipid droplets (clustered), shape of secretory droplets 4b: Brush border 4c: Primary lysosomes 6a: Stabile and labile microtubules 6b: Cross- sectional and longitudinal sections of cilia and basal bodies. They have 9 pairs of outer doublets and a central pair of a single microtubule. 6c: Cross - sectional and longitudinal sections of cilia and basal bodies. Notice that the outer doublets, but not the central pair microtubules are continuous with microtubules of the basal bodies. 8h: Macrophages contain many heterophagic vacuoles. 10c: Dendritic processes. (They have a high density of intermediate filaments in the cytoplasm.) 10d: Neurofilaments can be seen in both myelinated and non-myelinated axons. 14: Shape of secretory droplets 19c: Long microtubules in cytoplasm of Sertoli cells, lipid droplets, and heterophagic vacuoles. 20: Lipofuscin granules 24: Non- clustered lipid droplets 25: Crystalloid inclusions Look over Pg. 73 in manual
