Definition

noun

A region inside the cell from where microtubules organize following depolymerization to turn into tubular structures arranged in distinct pattern and number.

This pericentriolar region plays two primary functions: to determine the organization of eukaryotic flagella and cilia, and to organize the spindle apparatus necessary in the pulling of chromosomes toward opposite sides during mitosis and meiosis. Hence, two important structures are associated with it: basal body and centrioles.
