sejtösszehúzódás
Sejtösszehúzódás refers to the process by which a cell shortens or contracts. This phenomenon is fundamental to many biological functions, particularly in muscle tissue. In muscle cells, known as myocytes, sejtösszehúzódás is driven by the interaction of specific proteins, primarily actin and myosin. These proteins form contractile filaments that slide past each other, causing the overall shortening of the muscle fiber. This controlled shortening generates force, enabling movement.
Beyond muscle, other cell types can also exhibit sejtösszehúzódás, though often through different mechanisms and for
The regulation of sejtösszehúzódás is complex and involves various signaling pathways, often initiated by external stimuli
