Skeletal muscle hypertrophy is characterized histologically by an increase in myofiber diameter. This can sometimes be difficult to detect histologically. Hypertrophy occurs as a result of increased workload and can occur either focally, as a compensatory reaction following the loss or atrophy of surrounding muscle, or more extensively, as a physiologic response to increased exercise demands..

Skeletal muscle fibers, also known as muscle cells, contain multiple nuclei. This is because during embryonic development, myoblasts fuse ... Abstract. Skeletal muscle cells are noteworthy for their syncytial nature, with each myofiber accumulating hundreds or thousands of nuclei derived from resident muscle stem cells (MuSCs). These nuclei are accrued through cell fusion, which is controlled by the two essential fusogens Myomaker and Myomerger that are transiently expressed within ... What type of muscle has a long thread-like shape, has numerous fibers, and cells are fused together? Cardiac. What type of muscle pumps blood through the heart's chambers and into the blood vessels? Smooth. What type of muscle keeps blood, fluids, and nutrients moving to necessary locations throughout the body? Skeletal.1. INTRODUCTION. Striated muscle is composed of two major muscle types—skeletal and cardiac. While the cardiac (heart) muscle functionally represents a set of self‐stimulating, non‐fatiguing muscle cells with an intermediate energy requirement, skeletal muscle represents a set of innervated, voluntary muscle cells that exhibit fatigue with high energy requirements (e.g., muscles of the ...Skeletal muscle tissue develops through the fusion of individual myoblasts, or early muscle cells. This fusion results in a characteristic multinucleated structure. Because the cells are fused and multinucleated, they form a structural syncytium. Nuclei of skeletal muscle tissue are oval-shaped and located at the periphery of the cell.Using these criteria, there are three main types of skeletal muscle fibers recognized (Table 10.5.1). Slow oxidative (also called slow twitch or Type I) fibers contract relatively slowly and use aerobic respiration (oxygen and glucose) to produce ATP. Fast oxidative (also called fast twitch or Type IIa) fibers have relatively fast contractions ...Skeletal muscle is found throughout the body and functions to contract in response to a stimulus. Skeletal muscle serves many purposes, including producing movement, sustaining body posture and position, maintaining body temperature, storing nutrients, and stabilizing joints. In contrast to smooth and cardiac muscle contraction, most skeletal muscle contraction is under voluntary control ...The fibers are small and clumped-packed together. Smooth muscle keeps blood fluids and nutrients flowing through the body. This muscle is a voluntary controlled muscle.
