vascularisation of a tooth root through scattered foramina of equal size on both outer and inner faces, e.g. in Hexanchidae. A secondarily anaulacorhizid condition occurs where the median groove of a holaulacorhizid type of root is totally overgrown to form a closed tube internally connected or merged with the pulp cavity (Herman et al., 1994)
