Confocal image of a sea squirt heart. The sea squirt heart is a tube made of a single layer of muscle cells. The contractile elements are the long striations stained red and the nuclei are also red....

Transmission electron micrograph of ventricle tissue of a mouse cardiac muscle. This image shows the intercalated discs between the muscle fibers as well as many mitochondria and lipid droplets.
