Electromechanical Coupling between Skeletal and Cardiac Muscle
Skeletal myoblasts form grafts of mature muscle in injured hearts, and these grafts contract when exogenously stimulated. It is not known, however, whether cardiac muscle can form electromechanical junctions with skeletal muscle and induce its synchronous contraction. Here, we report that undifferentiated rat skeletal myoblasts expressed N-cadherin and connexin43, major adhesion and gap junctio...
متن کاملElectromechanical Coupling in Cardiac Dynamics: The Active Strain Approach
The coupling between cardiac mechanics and electric signaling is addressed in a nonstandard framework in which the electrical potential dictates the active strain (not stress) of the muscle. The physiological and mathematical motivations leading us to this choice are illustrated. The propagation of the electric signal is assumed to be governed by the FitzHugh–Nagumo equations, rewritten in mate...
متن کاملElectromechanical coupling I. Introduction.
In skeletal muscle fibres contraction is initiated by the action potential which travels inward along the transverse tubular system and causes in some way the release of Ca from the terminal cisternae of the sarcoplasmic reticulum (SR). Ca-release is probably controlled by a potential-sensor (intram em brane charge movement) in the wall of the T-system which in a triad is about 10 20 nm apart f...
متن کاملBiomechanics feedback for rowing.
Factors that affect boat speed are important determinants of rowing performance and should form the basis of feedback to rowers and their coaches. Biomechanical analysis of rowing has led to variables that are causally linked to boat speed. With modern technology, these variables can be measured and feedback can be presented instantaneously on-water, or be presented simultaneously with video af...
