The tightly paired homologous regions are joined by a ladderlike longitudinal structure called the synaptonemal complex. |

On the basis of this ladderlike conception were built systems of rising transcendency, starting from a material basis and rising to a spiritual pinnacle. |

The nervous system, ladderlike in some primitive pedunculate barnacles, is condensed in scalpellomorphans and sessile barnacles into a single mass. |
