Subpellicular Microtubules

Reference work entry

Components of the  pellicle of many  Protozoa where the single outer membrane (e.g., trypanosomes) or the membranous complexes ( Apicomplexa,  Ciliophora) have microtubules (∼25 nm in diameter) underneath them ( Pellicle, Figs. 2, 3, and 4). In coccidians the number of microtubules is species-specific (e.g., Toxoplasma has 22) and they are anchored at the apical  polar ring ( Coccidia/ Host Cell Invasion/Motility).
