Axoneme
Definition
A fundamental internal structure, formed by an organized complex of cylindrical microtubules, constituting the central axis and motor skeleton of cilia and flagella in eukaryotic cells. The classical structural configuration follows the '9+2' geometric pattern, composed of nine peripheral microtubule doublets symmetrically arranged around a central pair, interconnected by delicate dynein and nexin bridges that facilitate propulsive oscillatory or undulatory movement.
