Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body. The human body contains three different kinds of muscle tissue: skeletal, smooth, and cardiac.
Full Answer
The three types of muscle tissue are skeletal, cardiac, and smooth. Skeletal muscle is attached to bones, has cylindrical cells, is striated, multinucleate, and voluntary control.
skeletal muscle cardiac muscle 平滑筋 Skeletal muscle is composed of very hard-working cells. Which organelles do you expect to find in abundance in skeletal muscle cell?
The major functions of muscle tissue are movement: body, parts, blood, and food; maintenance of posture (skeletal muscle); joint stability: shoulder/knee (skeletal); heat production-85% (skeletal).
Skeletal muscle is attached to bones, has cylindrical cells, is striated, multinucleate, and voluntary control. Cardiac is the heart, branched cells, striated, uni or dinucleate, and involuntary. Smooth muscle is in walls of hollow organs, spindle-shaped cells, nonstriated, uninucleate, and involuntary.
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
The muscle that makes up the heart is called cardiac muscle. It is also known as the myocardium (say: my-uh-KAR-dee-um). The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body.
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
Cardiac muscle differs from skeletal muscle in that it exhibits rhythmic contractions and is not under voluntary control. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart's pacemaker.

Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick. Often, only one part of the heart is thicker than the other parts. The thickening can make it harder for blood to leave the heart, forcing the heart to work harder to pump blood.
The wall of the heart separates into the following layers: epicardium, myocardium, and endocardium. These three layers of the heart are embryologically equivalent to the three layers of blood vessels: tunica adventitia, tunica media, and tunica intima, respectively.
Smooth Muscle ExamplesSmooth muscle is present in the blood vessels.It is also present in the gallbladder.It is present in the intestines.Smooth muscle is present in the walls of the stomach.It is present in the urinary system.It is present in the iris of the eye.The prostate is also made of smooth muscles.More items...•
The cardiac muscle is the muscle of the heart. Both cardiac muscle and the skeletal muscle have rather conspicuous striations when viewed under the microscope (in which the smooth muscle is lacking, thus the name).
Tendons (tough bands of connective tissue) attach skeletal muscle tissue to bones throughout your body. Your shoulder muscles, hamstring muscles and abdominal muscles are all examples of skeletal muscles.
The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape. The contraction of cardiac muscle is involuntary, strong, and rhythmical.
how do cardiac muscles differ from skeletal muscle cells? Cardiac muscle is involuntary and found only in the heart. Cardiac muscle is striated, but the bundles are connected at branching, irregular angles called intercalated discs. Skeletal muscle is striated in regular, parallel bundles of sarcomeres.
