Boundary Between the Satellite Cell Sheath and the Connective Tissue Space
The outer contour of the satellite cell sheath faces the connective tissue space, in which collagen fibrils (Figs. 3B, 4A, B, 10A, 11A, 12A, B, 16A, B, 18, 20), connective tissue cells, and sometimes microfibrils also (Fig. 12A) are present. A thin layer of apparently amorphous material (basal lamina; for the precise significance of this term, see footnote on p. 4) follows the outer contour of the satellite cell sheath (Figs. 3A, 4A, B, 12A, 14A, 15), being separated from it by a light space (lamina lucida). The basal lamina is continuous from one satellite cell to the next; i.e., it bridges the 15–20 nm spaces between adjacent satellite cells.
