The cingulum divides the cell into an anterior body portion, the episome (epicone, epitheca) and a posterior hyposome (hypocone, hypotheca). If the distal and proximal ends of the cingulum do not meet at an equal level at the sulcus they are said to be displaced. Displacement may be descending (left-handed; the most common condition), in which the proximal (left) end is more anterior, or ascending (right-handed). The degree of displacement is measured in cingular-widths, given from the upper edges.
