11. Mouse models employing transgenesis have highlighted the function of N-cadherin in cardiac muscle . 12. Cardiac muscle undergoes aerobic respiration patterns, primarily metabolizing lipids and carbohydrates.13. Emerin is a serine-rich protein with an skeletal and cardiac muscle . 14. This protein is expressed most abundantly in skeletal and cardiac muscle . 15. FHL1 has been shown to be heavily expressed in skeletal and cardiac muscles . 16. This increases the contractile force of the cardiac muscle , resulting in increased stroke volume. 17. Plakoglobin is essential for normal development of intercalated discs and stability of cardiac muscle . 18. In cardiac muscle , emerin is also found complexed to glycogen synthase kinase 3 beta. 19. Automaticity refers to a cardiac muscle cell firing off an impulse on its own. 20. :I would be skeptical because cardiac muscle is spontaneously pulsatile.
