Cardiac muscle Cardiac muscle. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body.

Types of Muscles in the Body Cardiac muscle is a type of muscle tissue that is only located in the walls of your heart. Because your hearts beats more than 100,000 times and pumps 7,200 liters of blood a day, cardiac muscle is designed to be highly resistant to fatigue and deliver consistent movements.

Muscles Each type of muscle has its own characteristics and function in the body. Cardiac muscle, as the name suggests, is found only in the heart. It is an involuntary muscle meaning that there is no conscious control over the action of the muscle, it is completely controlled by autonomic functions.ecause the heart must beat constantly and often react quickly, cardiac muscles are some of the hardest working muscles in the body. Smooth muscles are found in many different locations throughout the body, such as the iris of the eye, the walls of arteries, surrounding the small intestine and stomach.

Muscle tissue Cardiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. These three types of muscle all form in the process of myogenesis. The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei. The myocardium is the muscle tissue of the heart, and forms a thick middle layer between the outer epicardium layer and the inner endocardium layer.

- Cardiac muscle is a syncytium in which the cardiac muscle cells are so tightly bound that when one of these cells is excited the action potential spreads to all of them and allows succinct coordinated contraction of the heart.

Cardiac muscle cell Cardiac muscle cells or cardiomyocytes (also known as myocardiocytes or cardiac myocytes) are the muscle cells (myocytes) that make up the cardiac muscle. Each myocardial cell contains myofibrils, which are specialized organelles consisting of long chains of sarcomeres, the fundamental contractile units of muscle cells.

- Cardiac muscle (heart muscle). This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised.he cause of this 'stripy' appearance is the bands of Actin and Myosin which form the Sarcomere, found within the Myofibrils. Skeletal muscles are also sometimes called voluntary muscles, because we have direct control over them through nervous impulses from our brains sending messages to the muscle.

Learn About Muscle Tissue Cardiac Muscle. Cardiac muscle is so named because it is found in the heart. Cells are joined to one another by intercalated discs, which allow the synchronization of the heart beat. Cardiac muscle is branched, striated muscle. The heart wall consists of three layers: epicardium, myocardium, and endocardium.

Heart or Cardiac Muscle Cardiac muscle is a specialized muscle only found in the heart. It is striated with narrow dark and light bands, similar to skeletal muscle. However, the bands are narrower and much shorter than skeletal muscle. One unique characteristic of cardiac muscle is that it does not fatigue.

Cardiac Muscle Tissue Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heart’s mass.ardiac muscle tissue is made up of many interlocking cardiac muscle cells, or fibers, that give the tissue its properties. Each cardiac muscle fiber contains a single nucleus and is striated, or striped, because it appears to have light and dark bands when seen through a microscope.

Characteristics of Cardiac Muscle Tissue Characteristics of Cardiac Muscle. Cardiac muscle is characterized by striped muscle fibers, connected together by intercolated disks, where the membranes are specialized to allow electrical signals to pass easily. Like smooth muscles, cardiac muscles can remain in contraction for a sustained period.t has characteristics similar to both smooth and skeletal muscle tissue, as well as specialized properties, that allow it to function with fast but sustained contractions, rapid conduction and coordinated movement.

Cardiac muscle, found only in the myocardium, contracts in response to signals from the cardiac conduction system to make the heart beat. Cardiac muscle is made from cells called cardiocytes. Like skeletal muscle cells cardiocytes have a striated appearance, but their overall structure is shorter and thicker.

What Is the Difference Between Smooth & Cardiac Muscle? Control. Smooth muscle and cardiac muscle are both involuntary muscles. Specialized cardiac muscle fibers make up the pacemaker that regulates your heart rate. This pacemaker, in turn, is under the control of the autonomic nervous system, the part of the nervous system that operates below your level of consciousness.ocation. Cardiac muscle forms the myocardium, or muscular wall of the heart. The major blood vessels arising from your heart, such as the aorta, also contain some cardiac muscle. Smooth muscle, on the other hand, is a major component of the walls of all blood vessels.
