IN DETAIL. Why does the stomach rotate clockwise around its vertical axis? The dorsal mesentery of the omental bursa grows and lengthens and is pushed to the left due to clefts on the right of the dorsal mesentary
SPECIFICALLY from what does the infracardiac bursa develop? SPECIFICALLY, where is it located? The superior recess of the omental bursa above diaphragm, cyst can develop posterior to root of lung
IN DETAIL, discuss how the pancreas becomes retroperitoneal. BE SPECIFIC The right side of the dorsal mesoduodenum and the left side of the dorsal mesogastrium fuse with the dorsal body wall
Discuss the development of the vertebral artery The dorsal ramus of the dorsal intersegment fuse via anastomosis between #1-7 forming the vertebral artery
