Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart .

2019年4月16日 · Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle. This muscle contracts when your heart beats, allowing blood to pump through your body. Read on...

2025年1月27日 · Cardiac muscle, in vertebrates, one of three major muscle types, found only in the heart. Cardiac muscle possesses contractile units known as sarcomeres and exhibits rhythmic contractions. The rhythmic contractions are regulated by the sinoatrial node of the heart and thus are not under voluntary control.

2024年1月26日 · Your heart is a muscular organ that pumps blood to your body. What is the heart? The heart is a fist-sized organ that pumps blood throughout your body. It’s your circulatory system ’s main organ. Muscle and tissue make up this powerhouse organ. Cleveland Clinic is a non-profit academic medical center.

2019年10月4日 · Cardiac muscle, also known as heart muscle, is the layer of muscle tissue which lies between the endocardium and epicardium. These inner and outer layers of the heart, respectively, surround the cardiac muscle tissue and separate it from the blood and other organs.

2024年6月22日 · The heart muscle is the myocardium or middle layer of the heart walls. The myocardium is responsible for the contractile function of the cardiac pump. Composed of cardiomyocytes, the heart muscle has distinctive cellular and physiological features, allowing it to generate force to maintain adequate tissue and organ perfusion throughout the body.

2024年8月16日 · At its core lies a unique tissue known as cardiac muscle. Unlike skeletal muscle, which allows for movement and flexibility, or smooth muscle that manages involuntary functions in organs, cardiac muscle has its own special role—keeping that relentless rhythm of …

2023年7月30日 · 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 heart is made up of three layers—pericardium, myocardium, and endocardium.

2023年8月8日 · Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium …

2024年10月24日 · Cardiac muscle is a remarkable tissue that plays a key role in maintaining the circulatory system’s functionality. Its unique properties allow it to contract rhythmically and tirelessly throughout an individual’s lifetime, ensuring …
