New research in PNAS, led by Da-Zhi ... Web17 jun. 2024 · Yes, a skeletal muscle does have multiple nuclei, or it is multinucleated, as does cardiac muscle. Smooth muscle, however, only has one nucleus per cell, or it is uninucleated. What are the three types of muscle cells? Muscles come in three different types in animals: cardiac, smooth and skeletal.
The primary function of muscle is contraction. Following contraction, skeletal muscle functions as an endocrine organ by secreting myokines – a wide range of cytokines and other peptides that act as signalling molecules. Myokines in turn are believed to mediate the health benefits of exercise. Myokines are secreted into the bloodstream after muscle contraction. Interleukin 6 (IL-6) is the most studied myokine, other muscle contraction-induced myokines include BDNF, FGF21, and S…
