Cardiac muscle tissue is made up of many interlocking cardiac muscle cells, or fibers.
The heart's natural pacemaker is made of cardiac muscle that signals other cardiac muscles to contract. Like visceral muscles, cardiac muscle tissue is controlled involuntarily. While hormones and signals from the brain adjust the rate of contraction, cardiac muscle stimulates itself to contract.  Click to read more below. 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 Definition of CARDIAC MUSCLE. : the principal involuntary-muscle tissue of the vertebrate heart made up of striated fibers joined at usually branched ends and functioning in synchronized rhythmic contraction. ADVERTISEMENT. noun.  Muscle Tissue. Muscle tissue is made up of muscle cells/fibers that use energy to contract and create a pulling force. Muscle tissue is a group of specialized cells that contract together at the same time to move something. Smooth muscle tissue is found on the walls of hollow organs and has short fibers with tapering ends. The third inner layer of the arteries is thick and is made of muscle and elastic fibers. The middle layer (of three) in the veins is a thin muscle tissue layer. The heart is comprised of many cardiac muscles. The epiglottis is a flap controlled by smooth muscles. An isolated cardiac muscle cell, beating. 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. Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. Cardiac 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. 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 Muscle tissue, one of the four major tissue types, plays the vital role of providing movement and heat generation to the organs of the body. Within muscle tissue are three distinct groups of tissues: skeletal muscle, cardiac muscle, and smooth muscle. Each of these tissue groups is made of specialized cells that give the tissue its unique properties. Skeletal muscle is the most common and widely distributed muscle tissue in the body, making up around 40% of the body’s total mass. There are three types of muscle tissues: skeletal, cardiac and smooth muscles. a. skeletal muscle: multinucleated, striated; attached to bones producing locomotion, general support and posture; producing heat. Contraction is voluntary, and not long-sustained.  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. Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems.
