In diplomonad species, such as Giardia, the axoneme may extend intracellularly up to 5um away from the plane of the plasma membrane. A set of four specialized microtubules that originates from the basal bodies and wraps around the ciliary pocket membrane, likely supporting its distinct flask shape.
