Cardiac muscle
The centrally located nucleus of this cardiac muscle fiber is are surrounded by myofibrils showing sarcomeres, A and I bands as well as Z and M lines. The H band is not readily apparent in this image. The alignment of the myofibrils creates the banding pattern of the entire fiber. Glycogen granules and mitochondria are also visible. 10,000x
