“…Elongation of the fibers is always the result of insertion of new contractile material into the terminal regions and is similar to that reported in fibers with cross-striation (Fischman, 1972;Goldspink, 1979;Muntz, 1990;Naidoo, 1993). However, an increased diameter of the fiber is not the result of peripheral deposition of new material, since new sarcomeres must be inserted into a geometrically defined system.…”

There are two different muscle fiber types in haplotaxids. The pseudo-circomyarian type is typical of Haplotaxis gordioides and the flattened circomyarian type of Pelodrilus leruthi. The mechanisms of growth in fiber size and in fiber number of the two fiber types in the hindmost region of adult specimens have been studied ultrastructurally. The increase in length and girth of the muscle fiber is always the result of the insertion of new myofilaments in the peripheral zones of the muscle cells. The increase in the number of fibers seems to be due to division of differentiated muscle cells.

“…Muscle formation, or myogenesis, involves the fusion of numerous progenitor muscle cells, or myoblasts, to form a single syncytial cell, or myotube [21,23]. Cell-cell recognition is a critical event prior to fusion and numerous cell surface receptors are thought to be involved, including cadherins [7,9,15,16,20,37], integrins [12,31], disintegrins [41], and NCAM [6,17,20] .…”

“…The development of the different fiber types occurs in the process of differentiation and growth of the muscle cells during embryonic and fetal life (for a review, see Muntz, 1990). In adult animals, the phenotype of a muscle fiber results from a combination of genetic and environmental effects, in which innervation is thought to play a role (Pette and Vrbova, 1985).…”
