Electron micrographs of the cardiac muscle cells in the orb-web spider, N. clavata. a: Cardiac muscle cells contain densely packed mitochondria (mi) and myofibrils (mf) within the cytoplasm. Adjacent cells are tightly connected by intercalated disc (cd). b: Cardiac muscle cells show myofibril striations with distinct sarcomeres defined by Z-lines. Multinucleate cardiac muscle cell that has more than one nucleus (nu) per cell is seen. 5 μm (a), and 2 μm (b)
