Cardiac muscle is a type of tissue that develops from the mesoderm during embryonic development. It develops from the cells of the primitive heart tube, aligns into chain like arrays, and has the same arrangement of its contractile filaments as seen in skeletal muscle. As the name suggests, cardiac muscle is only found in the heart. 12. Differences between cardiac and skeletal muscle.
