Cardiac Muscle Branched. Smooth muscle tissue contraction is responsible for involuntary movements in the internal organs. The heart wall consists of three layers.
What type of muscle moves body fluids. The anatomy of the heart includes the chambers and their vessels and the coronary blood vessels. Epicardium myocardium and endocardium.
Cardiac muscle cells have a branched shape so that each cell is in contact with three of four other cardiac muscle cells.
Cardiac muscle fibers have a single nucleus are branched and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts. Cardiac muscle is striated muscle that is present only in the heart. Myocardium is the middle muscular layer of the heart. Cardiac muscle is striated like skeletal muscle as the actin and myosin are arranged in sarcomeres just as in skeletal muscle.
