The linkage complex consists of a spindle shaped mid piece bordered,
in one plane, by several rails that have subunits that pass through
the ER membrane (see Fig. 21). Thin filaments splay out from both tips
of the mid piece and pass toward the surface of the pellicle (Fig.
18). The molecular biology or biochemistry of these elements remains
to be done. We can only guess that they are involved in calcium
movement between the myoneme (my) and the ER and thus in
regulating myonemal contraction and relaxation. m,
