Muscle samples were taken for histochemical analysis, SDH and PFK were estimated and myofibers were identified. Myosin ATPase and other enzymatic activities serve to identify slow muscle fibers and rapid muscle fibers in the subject. Main findings In the first study, Gollnick et al. May have recorded for the first time how myosin ATPase and other enzyme staining provides evidence for a slow and rapid convulsive fiber distribution. Skeletal muscle from a trained endurance athlete has been reported to have a number of slow muscle fibers with higher oxidative capacity, which has previously been confirmed by multiple cross sections.

In contrast, less HERV activity was observed in the rectum, stomach, heart and skeletal muscle. Muscle tissue represents highly differentiated non-dividing multinucleated cells with highly specialized work. This is in contrast to tissues with high proliferation rates (uterus, placenta and dermal cells) and metabolism (fetal cells) and tissues with exocrine and endocrine activity (breast and thyroid). Thus, HERV activity may reflect the level of transcriptional activity and proliferative activity in situ.

Students believe that muscles become thicker if you stop exercising. Students need to understand that muscle cells can not become fat (fat) cells and understand the definition of the organization. The cells are differentiated. This means that cells can differ from one another in structure and function, but they maintain the same function throughout the life of the cells. The amount and number of muscle cells and adipocytes may increase or decrease depending on changes in nutrition and activity, but cells do not change from one form to another.

Cell differentiation is the process of producing different functional cell types during development. For example, neurons, muscle fibers, and hepatocytes (hepatocytes) are well-known types of differentiated cells. Differentiated cells typically produce large amounts of protein necessary for a particular function, so that they give a characteristic appearance that allows them to recognize them under a light microscope. The genes encoding these proteins are highly active. Typically, their chromatin structure is very open, allowing the entry of transcriptases, and certain transcription factors bind regulatory sequences in DNA and activate gene expression. For example, NeuroD is an important transcription factor for neuronal differentiation, myogenic differentiation myogenin, and hepatocyte differentiation HNF4.
