Understanding the Myocardium

This video tutorial by Matt from Kenhub focuses on the myocardium, the middle muscular layer of the heart's walls. It explains the heart's four layers: pericardium, epicardium, myocardium, and endocardium, and their roles in aiding the heart's pumping action. The myocardium is highlighted for its functions in providing structural support, assisting in cardiac contraction and relaxation, and conducting electrostimulation. The tutorial encourages viewers to explore more anatomy resources on Kenhub.
