Abdomen, Pelvis & Perineum
Which of the following structure doesn’t develop in mesentery of stomach (AIIMS – Nov - 2010)
Pg. 216, 219; Langman’s embryology (11th Ed.)
1. Kidneys are present on the posterior abdominal wall retro-peritoneally.
2. Stomach has a double fold of peritoneum (mesentery/meso-gastrium) having two parts
a. Ventral mesentery – Liver develops in it and the mesentery then gives peritoneal folds like falciform ligament, lesser omentum etc.
b. Dorsal mesentery – Spleen and pancreas develop in it and give rise to peritoneal folds like gastro-splenic and lieno-renal ligaments.
3. Pancreas develops in the meso-duodenum and meso-gastrium. Initially it is intra-peritoneal but later it becomes retro-peritoneal (hence, it is called secondarily retroperitoneal organ).
