action potentials arise spontaneously in specialized cardiac muscle cells and then spread throughout a large population of cardiac muscle cells as if they were a functionalsyncytium. This can result in coordinated contraction of a large region of the heart muscle. The frequency of such action poten...
The cardiac conduction pathway consists of: A. Specialized cardiac muscle cells within the heart. B. nerve cell pathways within the heart. C. both A and B. D. both A and B, and the skeleton of the heart. What is the source of energy for skeletal, smooth, and cardiac muscles?
The ultrastructure of the muscle cells of the left ventricular wall of the heart of mammals has been described with respect to the distinct cellular constituents. The sarcolemma has the general features of the surface membranes of cells, but additionally contains specialized junctions. Moreover, ...

cardiacmuscleis strong and has a long durability, which sustains its unique heartbeat. The Cardiac hearts muscle has the capability to spread rapid electrochemical signals throughout the body, to help keep the contraction ongoing and function suitably. The contraction of theheartis to help support ...
Muscle cells: Muscle tissues in the human body are of three types, namely, skeletal muscle, cardiac muscle, and smooth muscle. Cardiac muscle tissue makes up the wall of the heart. The skeletal muscle is attached to the skeletal ...
they are generally much smaller than the contractile cells and have few of the myofibrils or filaments needed for contraction. Their function is similar in many respects to neurons, although they are specialized muscle cells. Myocardial conduction cells initiate and propagate the action potential (the...
structural support for cardiomyocytes and sustain the homeostasis of the cardiac extracellular matrix [13]. Mural cells in the vessel wall include smooth muscle cells and pericytes, which are vital for vascular integrity and cardiac function [14]. ECs constitute the inner layer of blood and ...
