The heart consists of a range of tissues. The most important one is cardiac muscle. The cells have the ability to contract and relax through the complete life of the person, without ever becoming fatigued. Each cardiac muscle cell is myogenic. This means it has its own inherent rhythm. Belo...

Congenital heart diseases often involve maldevelopment of the evolutionarily recent right heart chamber. To gain insight into right heart structure and function, we fine-tuned deep learning models to recognize the right atrium, right ventricle and pulmonary artery, measuring right heart structures in 40...
Heart Terms Myocardium – The muscle that forms the heart wall. Creates the “beat” of the heart. Endocardium – A tough membrane that. The heart and its parts. Blood Vessels Artery – a blood vessel that moves blood away from the heart Vein – a blood vessel that moves blood towards...
these filaments regulate heart beat via cardiac muscle contractions in the presence or absence of calcium ions by changing their conformations. This work may have application in the development of new drugs for treating heart conditions caused by mutations that affect these structures and functions. ...
of this conserved vertebrate-exclusive protein remain unknown. Here we present the crystal structure of a heart-shaped dimer of the extracellular part of human EpCAM. The structure represents acis-dimer that would form at cell surfaces and may provide the necessary structural foundation for the ...
The GLUT proteins have varied physiological functions that are related to their principal substrates, the cell type in which the GLUTs are expressed and the extent to which the proteins are associated with subcellular compartments. Some of the GLUT proteins translocate between subcellular compartments ...
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. ...
Muscle is a fibrous tissue that exerts contractile force for diverse motile functions, such as heartbeat and body movement, in animals. The force generation is associated with shortening of sarcomeres, which are the micron-sized cylindrical structures that are periodically arranged and connected in ...
