Cellular Dynamics Quiz

Cell migration in response to external cues involves the dynamic reorganization of the actin, microtubule, and intermediate filament cytoskeletons, coordinated with membrane trafficking events that deliver new membrane to the leading edge and internalize adhesive receptors from the cell rear.

Living cells are described as dynamic machines that integrate biochemical and mechanical information, continuously adapting and responding to their local environment.

The targeted delivery of receptors, transporters, secretory and endocytic cargo to the appropriate destination is essential for cell function.
