APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, with the other two being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart.

Detailed explanation-2: -Your heart is actually a muscular organ. An organ is a group of tissues that work together to perform a specific function. In the case of your heart, this function is pumping blood throughout your body. Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle.

Detailed explanation-3: -Histologically, heart muscles are composed of cells called cardiomyocytes that have unique structures and properties correlating to their contractile function. [1] Cardiomyocytes are striated, uninucleate muscle cells found exclusively in the heart muscle.
