The differentiated muscle cell in postnatal muscle is the muscle fiber, a highly specialized, long, cylindrical cell that can range in diameter from 10 to 100 mm and in length from millimeters up to many centimeters. Growth of muscle can occur in three ways (1) by an increase in muscle cell numbers, (2) by an increase in muscle fiber diameter, and (3) by an increase in fiber length. However, growth in cell numbers is limited to the prenatal and immediately postnatal period,. Growth factors are hormones or hormone-like compounds that stimulate satellite cells to produce the gains in the muscle fiber size. These growth factors have been shown to affect muscle growth by regulating satellite cell activity. Hepatocyte growth factor (hgf) is a key regulator of satellite cell activity. So now that you know the three main mechanisms of muscle growth, the next question is how do hormones affect muscle growth? How do hormones affect how muscles grow? Hormones are another component largely responsible for muscle growth and repair because of their role in regulating satellite cell activity. Instead, muscles grow larger through a combination of muscle cell growth as new protein filaments are added along with additional mass provided by undifferentiated satellite cells alongside the existing muscle cells. Biological factors such as age and hormone levels can affect muscle hypertrophy. Muscle hypertrophy involves an increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage and myofibrillar hypertrophy, which focuses more on increased myofibril size. It also slows sugar absorption into your bloodstream, promotes satiety and suppresses appetite. If youre looking to build muscle and strength, fiber can help. While it doesnt directly cause muscle growth or fuel your gains, it does other things that can boost your exercise performance. 18 a skeletal muscle fiber is surrounded by a plasma membrane called the sarcolemma, with a cytoplasm called the sarcoplasm. A muscle fiber is composed of many fibrils packaged into orderly units. The orderly arrangement of the proteins in each unit, shown as red and blue lines, gives the cell its striated appearance. In the neuron an action potential produces the nerve impulse, and in the muscle cell it produces the contraction required for all movement.
