Heart muscles, also known as cardiac muscle or myocardium, form the thick, middle layer of the heart wall and are responsible for its pumping action.
Key Characteristics of Heart Muscles:
- Location: The heart muscle, or myocardium, is the middle layer of the heart wall.
- Composition: It is one of the three types of muscle in the body, alongside skeletal and smooth muscle.
- Structure: The myocardium is surrounded by an outer layer called the epicardium (also known as the visceral pericardium) and an inner layer known as the endocardium.
- Function: Heart muscles contract to pump blood throughout the body.
