| Since the description of a helicoidal pattern of muscle fibres in teleost fishes by Van der Stelt (1968), Alexander (1969) stated that there are two basic patterns. One is found in selachians and primitive bony fishes as Anguilla and Salmo, whereas it is also found in the caudal peduncles of teleosts, which are considered more advanced. More anteriad a quite different pattern is found, resembling the helicoidal pattern. The elucidation of this pattern was disclosed by both Van der Stelt (1968) and Alexander (1969) by reconstruction from horizontal, as well as vertical serial sections. Van Raamsdonk et al. (1974), in a study of the early development of the myomeres of Brachydanio rerio, observed a transition of a primary longitudinal course of muscle cells... |

| Morphometric analysis was carried out on wing muscles of the House Fly (Musca domestica), ranging from the pupation period to death. In the first week a clear increase was found in the percentage of food reserve consumed by the cell components. Both fibrils and sarcosomes increase in circumference during the first week. The sarcosomes then fuse. After the first week few changes occur. The sarcosomal volume increases in male flies. No disintegration or degeneration of the muscle cells appears with old age. Even the fact that the wing of the male flies exhibits abrasion earlier than that of females cannot be correlated with changes in the wing muscles. The ratio of fibrils to sarcosomes is greater than two to one. This ratio differs in males and females. A... |
