PATHOLOGY

Detailed explanation-1: -Cellular Level 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: -Overview. 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.

Detailed explanation-3: -The dogma was introduced that adult cardiomyocytes are terminally-differentiated cells, which are irreversibly withdrawn from the cell cycle. These cells are unable to proliferate, but can perform their physiological functions, undergo cellular hypertrophy, and ultimately die by apoptosis or necrosis.

Detailed explanation-4: -Cardiac muscle cells They are around 0.02 mm wide and 0.1 mm (millimeters) long. Cardiomyocytes contain many sarcosomes, which provide the required energy for contraction. Unlike skeletal muscle cells, cardiomyocytes normally contain a single nucleus.
