Filoponia

Filopodia are slender, finger-like projections that extend from the surface of a cell. Composed of aligned actin filaments, they function like sensory antennas, helping cells explore their environment, migrate, and communicate. Filopodia probe the surroundings for signals, obstacles, or nutrients, guiding processes such as tissue development, wound healing, and immune responses. Their dynamic structure allows them to rapidly extend and retract, providing cells with flexibility in navigating complex environments. Overall, filopodia play a crucial role in cell movement and environmental sensing within the body.
