Spleen projects into which of the following space of peritoneal cavity?

"Being developed in the dorsal mesogastrium, the spleen projects into the greater sac surrounded by peritoneum of the original leaf of the dorsal mesogastrium."- Ref: Last's Anatomy. Spleen stas to develop in the 4 the week of gestation as a mesenchymal condensation in the dorsal mesogastrium of the lesser sac. In the following weeks these early mesenchymal cells differentiate to a vascular lymphatic pedicle that eventually forms the spleen. When the embryo is 10cm long dorsal mesogastrium can be divided into anterior and posterior pa. Posterior pa forms the splenorenal ligament. It contains splenic aery and vein. Anterior pa of dorsal mesogastrium develops into gastrosplenic ligament and contains sho gastric vessels.
