FIGURE 8.10 | Longitudinal and Transverse

Sections of Cardiac Muscle

Cardiac muscle fibers exhibit similar features that are seen in skeletal muscle
fibers. This figure illustrates a section of a cardiac muscle cut in both

longitudinal (upper portion) and transverse (lower portion) planes. The cross-
striations (2) in the cardiac muscle fibers closely resemble those of skeletal
muscles. In contrast, the cardiac muscle fibers show branching (5, 10) without
