Complete Mesenteries: Mesenteries which extend from the column into the coelenteron and are attached to the actinopharynx (Carlgren, 1949; p. 9). Complete mesenteries can be directive or non-directive mesenteries. Complete is the more modern term and more commonly used when compared to the older term; perfect.
