What are three muscles in the heart?
The heart primarily consists of three types of muscles: the myocardium, which is the thick, muscular middle layer responsible for contracting and pumping blood; the endocardium, a thin layer lining the heart chambers; and the epicardium, which is the outer layer that also forms part of the pericardium. The myocardium is the most critical for heart function, as it enables the heart to contract rhythmically. Additionally, the heart contains specialized muscle fibers known as Purkinje fibers that help coordinate contractions.
