The development of the midgut explained very simply! • If you are completely new to embryology and you want to understand it quickly, this should be the first video you watch: • • Introduction to Embryology - Fertilis... • Post any questions you have about the video below, I read all the comments: • -------------------------------- • Recommended Text • -------------------------------- • Easy Embryology is a book that is dedicated to the simplification of embryology. It is available at https://drminass.com/product/easyembr.... Contact Dr. Minass for more information. • ---------------------------------------- • Interact With Dr. Minass! • ---------------------------------------- • Website - https://www.drminass.com • Email - [email protected] • Patreon - / drminass • Facebook - / m1na55 • Instagram - @m1.nass • Post - Address to: • Minass • Parcel Locker 10106 04448 • 59 Penshurst Street • Willoughby, NSW • Australia 2068 • Summary for your notes: • midgut communicates with the yolk sac with the vitelline duct (yolk stalk) • midgut begins in the grown human distal to the entrance of the bile duct into the duodenum, until the junction between the proximal 2/3 of the transverse colon and the distal 1/3. • midgut is supplied by superior mesenteric artery] • midgut rapidly elongates forming a primary intestinal loop • cephalic limb of the loop becomes the distal duodenum, jejunum, and some of the ileum • caudal portion becomes the rest of the ileum, caecum, appendix, ascending colon, and proximal 2/3 of the transverse colon • the midgut rotates 90 degrees during physiological herniation (counter-clockwise) • when the intestinal loops retract into the abdominal cavity due to liver growth declining and an increased cavity, the midgut rotates another 180 degrees • initially the cecum is in the right upper quadrant (RUQ), but it descends into the iliac fossa (RIF) • Abnormalities: • gastroschisis, Meckel's diverticulum (persitence of the vitelline duct), volvulus (malrotation: only 90 degrees instead of 270, leading to bowel being retracted first and therefore being on the left side), atresia and stenosis
