  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 is specifically muscle tissue of the heart.  It is smooth just like skeletal muscle tissue but has special  characteristics that help it to contract at â¦ fast, steady rates.ardiac muscle is dense and packed tightly. The muscle fibers are striated and branched and have intercalated discs. The nature of the heart muscle is to communicate fiber to fiber so that each fiber can work with the others to achieve the coordinated pumping action that we need out heart to do.
