Oct 4, 2019 · Cardiac muscle, also known as heart muscle, is the layer of muscle tissue which lies between the endocardium and epicardium. These inner and outer layers of the heart, respectively, surround the cardiac muscle tissue and separate it from the blood and other organs.
Jun 21, 2019 · Cardiac muscle tissue forms the heart and contracts involuntarily to keep it pumping blood. Learn about its structure, function, and conditions that affect it, such as cardiomyopathy.
Cardiac muscle, in vertebrates, one of three major muscle types, found only in the heart. Cardiac muscle possesses contractile units known as sarcomeres and exhibits rhythmic contractions. The rhythmic contractions are regulated by the sinoatrial node of the heart and thus are not under voluntary control.

Sep 2, 2023 · Cardiac muscle tissue is located in the middle of three layers of the heart, called the myocardium. Problems in the myocardium can cause heart failure and arrhythmias or contribute to sudden cardiac death. This article discusses the role of muscle tissue in the heart and ways to keep your heart's muscle tissue healthy.
The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation.
Jul 30, 2023 · The primary function of cardiac muscle is to pump blood into circulation by generating sufficient force. The mechanism behind each coordinated contraction involves the cardiac muscle and electrical impulses.
