Electron Micrograph of an Elastic Fibre in Cross Section

The electron micrograph is a cross section of elastic fibres of a fetal ligamentum nuchae. It clearly depicts the two regions of an elastic fibre: the amorphous elastin core and the fibrillin mantle.


FIGURE 6 This cross-section of an 8-nlonth fetal ligamentum nuchae demonstrates two elastic fibers of different size. The larger fiber has a central nonstaining area (ca), which is continuous and irregular in shape, and both peripheral and centrally located 100 A fibrils (f). The fibrils in the deep recess of the fiber account for the appearance of centrally placed fibrils in longitudinal sections (Figs. 5 a and b). The smaller elastic fiber on the right contains three separate central areas (ca) each of which is surrounded by fibrils (f). This fiber is similar to the elastic fibers in the rat tendon seen in Figs. 8 a and 9 a. Fixed with OsO4 followed by formalin. Stained with uranyl acetate and lead. The inset contains a higher magnification of several of the fibrils that surround and are embedded in the elastic fiber. These fibrils present a tubular profile and are similar to those in the rat tendon in Fig. 12. Fig. 6, X 56,500; Inset, × 153,000.
