What are 3 characteristics of cardiac muscle?

Cardiac muscle is striated muscle that is present only in the heart. 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.Click to see full answer. Besides, what are the characteristics of cardiac muscle?Cardiac muscle cells are found only in the heart, and are specialized to pump blood powerfully and efficiently throughout our entire lifetime. Four characteristics define cardiac muscle tissue cells: they are involuntary and intrinsically controlled, striated, branched, and single nucleated.Also, what are the four characteristics of muscle tissue? All muscle tissues have 4 characteristics in common: excitability. contractility. extensibility – they can be stretched. elasticity – they return to normal length after stretching. Also question is, what is unique about cardiac tissue? Like skeletal muscle, cardiac muscle cells are striated due to a similar arrangement of contractile proteins. Unique to the cardiac muscle are a branching morphology and the presence of intercalated discs found between muscle fibers.What is 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.
