Also, researchers consider the composition of both the plasm and the membrane of the cilium to be detectably different from that in the non-ciliary cytosol and plasma membrane (e.g. in terms of calcium ion concentration, membrane lipid composition, and more). For this reason, the term "ciliary plasm" is not linked to "cytoplasm". cilium cytoplasm microtubule-based flagellum matrix cilial cytoplasm
