APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control. The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action.

Detailed explanation-2: -[1] Cardiomyocytes are striated, uninucleate muscle cells found exclusively in the heart muscle.

Detailed explanation-3: -Cardiac muscle is highly organized and contains many types of cell, including fibroblasts, smooth muscle cells, and cardiomyocytes.
