  No. Cardiac muscles are attached to the pericardium-a layer of tissue that surrounds the heart and the Great Vessels. The sac rests on the diaphragm and is connected b â¦ y various bits of connective tissue to the thoracic cavity.t each end of the muscle the collagen fibers of the epimysium, perimysium and endomysium come together to form a bundle known as a tendon. If they form a broad sheet it is ca â¦ lled an aponeurosis. I think tendon is what you're looking for. 5 people found this useful.
Cardiac Muscle Tissue. Cardiac muscle tissue is only found in the heart. Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle ([link]). However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell.
