Fig. 7.1.37. Multitubular body derived from endoplasmic reticulum. Multiple non-membranous bridges between individual tubules and layers of finely granulofilamentous material between rows of tubules are specific ultrastructural participants of this organelle of unknown significance. A transition between the lamellar body and multitubular body is apparent at the bottom right. Cf. Figs. 7.1.13 and 7.1.14. This artistic rendition (not 3D reconstruction) resulted from analyzing many tens of individual sections. (Rat, lateral geniculate and ventrobasal nuclei.) Download the high resolution image.
