Learn about cardiac muscle tissue and its unique structure, function, and role in the heart's blood pumping and electric signal transmission.
cardiac muscle- the muscle tissue of the heart; adapted to continued rhythmic contraction heart muscle muscular tissue,muscle- animal tissue consisting predominantly of contractile cells ticker,heart,pump- the hollow muscular organ located behind the sternum and between the lungs; its rhythmic contraction...
A healthy heart comprises various cell types, including cardiomyocytes, endothelial cells, fibroblasts, immune cells, and among others, which work together to maintain optimal cardiac function. These cells engage in complex communication networks, known as cell-cell interactions (CCIs), which are essent...
The heart relies heavily on oxidation of fatty acids for energy production. However, excess storage of fatty acids as triglycerides, within heart muscle cells, frequently observed in patients with obesity and diabetes, is often associated with cardiac dysfunction. The question remained: was this cause...

The human heart is a complex, multicellular organ with limited regenerative capacity. In vitro modeling of the human heart is not only important to better understand the composition and function thereof, but also to understand diseases or drug response. Cardiac tissue engineering and three-dimensional...
and small amounts are found in the superior vena cava andpulmonary vein. The cardiac muscle is not under conscious control; it has an automaticity center which responds to the autonomic nervous system when needed (see section Impulse Conduction). In the heart,cardiac muscle cellsare joined in ...

The heterogeneity of functional cardiomyocytes arises during heart development, which is essential to the complex and highly coordinated cardiac physiological function. Yet the biological and physiological identities and the origin of the specialized cardiomyocyte populations have not been fully comprehended. ...
