This condition is more common in patients with a family history of the disease. e mechanisms of calcium, actin, and myosin in cardiac muscle should be learned as identical to those of skeletal muscle. Only muscle tissue per se, has cells with the ability to contract. This line, an intercalated disc, assists in passing electrical impulses efficiently from one cell to the next while maintaining the strong connection between neighboring cardiac cells, allowing the cardiac muscle cells to synchronize the beating of the heart. Contractions of smooth muscles are involuntary, so they are not under conscious control. https://openstax.org/books/anatomy-and-physiology/pages/11-2-naming-skeletal-muscles. Quantitative RT-PCR results indicate that motor neuron presence has a positive effect on myotube maturation, suggesting neural incorporation influences muscle development and maturation in vitro. Skeletal muscles generate heat as a byproduct of their contraction and thus participate in thermal homeostasis. YouTube.
