Webb18 mars 2024 · Structure of Smooth Muscle Smooth muscle fibres are elongated and spindle-shaped cells which taper at both ends. This distinctive shape, along with the presence of a single central nucleus, helps to identify it histologically. These fibres are thousands of times shorter than skeletal muscle fibres. Figure 1 – Smooth muscle fibres WebbThe nuclei of skeletal muscle tissue are oval-shaped and located at the periphery of the cell as they are pushed there when fusing. Satellite cells are situated between the external lamina and sarcolemma.

WebbHere, they acquired a myofibroblast phenotype and when exposed to appropriate chemical stimulus, developed tension and cell shortening, similar to those of striated and smooth muscle cells. Myofibroblasts contained a molecular motor—the non-muscle myosin type IIA (NMMIIA) whose crossbridge (CB) kinetics are dramatically slow compared with … WebbSmooth muscle cells are not striated, uninucleate and involuntary. Finally, cardiac muscle is found in the heart and works to contract the organ to pump blood throughout the body. Of note, cardio myocites, or cardiac muscle cells are attached to each other through very strong junctions known as intercalated discs.
