This module introduces an equation to calculate roundness in the context of understanding how myosin contributes to cell shape. It is intended for an introductory biology audience.
Student Introduction: Fibrous elements of the cytoskeleton, including microtubules and filaments, help maintain cell shape. For example, amoeba movement involves interactions of myosin and actin in the microfilaments in the cell cytoskeleton. Myosin is normally dispersed throughout the cell, but locally assembles and disassembles as necessary to drive movement.
