Dimensions and number of cells -
Muscle fibers can be increased due to two main processes - hypertrophy
and hyperplasia.
The first leads to an increase in cell size within the
tissue, and the second - means increase in cell number. Despite the
similarity of names between these processes, there are very important
differences http://www.somanabolicmusclemaximizereviewscam.com/
Hypertrophy - is usually controlled growth in response to
external stimuli, which flows within certain limits. For example, the
fat cells are able to significantly increase their size in terms of
overeating or reduce the shortage of food.
The number of fat cells
remains unchanged, but the fat reserves thus can vary over a
considerable range. Hyperplasia provides a more rapid growth, because it
is guided by hormonal signals, or may be due to uncontrolled
cancer-causing changes. Hyperplasia is controlled process and, for
example, in the case of increasing the production of red blood cells
prior to stem after significant blood loss. Uncontrolled hyperplasia is a
cancer.
When the tumor begins to grow which means the uncontrolled
increase in the number of cells. The tumors are usually dense and
well-marked. In both cases, increasing the number of cells is not
accompanied by their growth. Large muscle groups such as biceps or
quadriceps, just full of muscle cells. If we take as an example the
biceps, it increases in size due to hypertrophy - that is due to the
increased growth of the size of each muscle cell.
