 (sī′tə-skĕl′ĭ-tn)
n.
The internal framework of a eukaryotic cell, composed of protein filaments that provide structural support and drive the movement of the cell and its internal components, typically divided into three categories (microfilaments, intermediate filaments, and microtubules) based on the diameter and composition of the filaments.
