Fig. 1.4.1.65. Three consecutive serial sections show a transversely cut dendritic shaft. At the point of a base of dendritic spines there is a multivesicular body (arrow) surrounded by branching tubules of smooth endoplasmic reticulum (cf. 3D reconstruction of the same site on the right). Scale cube = 0.1 µm per side. (Hippocampus, rat.)
