Detailed explanation-1: -Cardiac muscle cells (cardiomyocytes) are striated, branched, contain many mitochondria, and are under involuntary control. Each myocyte contains a single, centrally located nucleus and is surrounded by a cell membrane known as the sarcolemma.
Detailed explanation-2: -The physiological properties of the cardiac muscle are: 1. Rhythmicity 2. Excitability 3. Contractility 4.
Detailed explanation-3: -There are two major types of cardiac muscle cells: myocardial contractile cells and myocardial conducting cells. The myocardial contractile cells constitute the bulk (99 percent) of the cells in the atria and ventricles.
Detailed explanation-4: -The cells of cardiac muscles are cylindrical, branched, and uni-nucleate. Cardiac muscles are involuntary muscles that contract rapidly but do not get fatigued. They control the contraction and relaxation of the heart.
