  • according to Hottinger (2006):

UMBILICAL CAVITY is the axial complex of interconnected passageways delimited by axial chamber walls, inner umbilical walls, folia, foramenal plates, and cover plates. Includes thus the umbilical canal systems. May be restricted by piles or plugs and communicates with the exterior through foliar apertures or vertical canals.
