raku lai ja lame liikumisorganell, mis aitab rakul "roomata" tahkel substraadil, The lamellipodium (plural lamellipodia) is a cytoskeletal protein actin projection on the leading edge of the cell. It contains a quasi-two-dimensional actin mesh; the whole structure propels the cell across a substrate.Within the lamellipodia are ribs of actin called microspikes, which, when they spread beyond the lamellipodium frontier, are called filopodia. The lamellipodium is born of actin nucleation in the plasma membrane of the cell and is the primary area of actin incorporation or microfilament formation of the cell., mööda aluspinda liikuva loomaraku esiserva tekkiv lame väljasopistus, millesse on koondunud aktiini kiudude võrgustik, Широкое и плоское выпячивание цитоплазмы клетки, образованное микрофиламентами. Обеспечивает возможность передвижения по твёрдому субстрату для клетки.
