PATHOLOGY

Detailed explanation-1: -Heart muscle makes up one of the earliest functioning embryonic organs that continues to contract and beat from development throughout a lifetime. Supplied by a complex system of coronary vasculature, cardiac lymphatics, and autonomic innervation, cardiomyocytes line the thickest layer of every chamber of the heart.

Detailed explanation-2: -Cardiac muscle, also called the myocardium, is one of three major categories of muscles found within the human body, along with smooth muscle and skeletal muscle. Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility.

Detailed explanation-3: -Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle.

Detailed explanation-4: -Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body.
