CARDIAC MUSCLE – 2
The upper figure shows cardiac muscle fibers sectioned longitudinally, and the lower figure cross-sectioned fibers.
Observe the main histological features of cardiac muscle fibers:
– Fibers organized in bundles
– Nuclei centrally located – highlighted in green after clicking or using the mouse. The position of the nuclei can be better distinguished in cross-sections of the fibers.
– Intercalated disks can be seen in longitudinal sections of the fibers. They are darker staining lines placed transversely to the fibers. Sometimes the intercalated disks may be poorly stained after hematoxylin and eosin staining.
Some of disks of the upper figure become highlighted in light green.
