The heart is made of cardiac muscle.
Understanding Cardiac Muscle
Cardiac muscle, also known as the myocardium, is one of the three main types of muscle tissue in the human body, the others being smooth muscle and skeletal muscle. A key feature of cardiac muscle, similar to skeletal muscle, is that it contains sarcomeres. These sarcomeres are the fundamental units responsible for muscle contraction. This arrangement allows the heart to powerfully contract and pump blood throughout the body.
Here's a breakdown of the key aspects of cardiac muscle:
- Location: Exclusively found in the heart.
- Function: Responsible for the heart's pumping action.
- Structure: Contains sarcomeres, similar to skeletal muscle.
- Other Types of Muscle: Different from smooth muscle and skeletal muscle.
