The other dimensions are moved through and vibrated in by the strings just like the extended dimensions. If you are made of strings then YOU are always and everywhere moving through them. You can't separate out one spacelike dimension or a group of them and say they FUNCTION different from other spacelike dimensions; the compaction is different from extension only if the topology of the compacting manifold is non-trivial, which is of course a constant interest of string theorists.
