The arrangement of axonemal microtubules in cilia and flagellum is referred to as 9 + 2 array which essentially means that the axoneme has:

1. nine doublets of radially arranged peripheral microtubules and two doublets of centrally located microtubules enclosed by a central sheath.
2. nine triplets of radially arranged peripheral microtubules and a pair of centrally located microtubules enclosed by a central sheath.
3. nine triplets of radially arranged peripheral microtubules and a centrally located protein hub not enclosed by a central sheath.  
4. nine doublets of radially arranged peripheral microtubules and a pair of centrally located microtubules enclosed by a central sheath.
