Overview
Microfilaments are a crucial component of the cytoskeleton, primarily composed of actin. They play vital roles in maintaining cell shape, enabling movement, and facilitating processes like muscle contraction and cell division. Their dynamic nature allows cells to adapt and respond to various stimuli...
Key Terms
Example: Actin filaments are found in muscle cells.
Example: Microfilaments help in cytokinesis by forming a contractile ring.
Example: Myosin pulls on actin filaments to shorten muscle fibers.
Example: White blood cells use microfilaments for cell motility to reach infection sites.
Example: Amoebas use microfilaments to extend their cell membrane and move.
Example: Microfilaments play a role in the migration of cells to the wound site.
