Midgut rotation Flashcards
Why does the midgut protrude into the umbilicus?
it is to large for the abdomen cavity at that poinT
What is the midget continuous with?
viteline artery (yolk sac)
What happens as the midgut protrudes into the umbilicus?
cranial part rotates 90 degrees counterclockwise
distal part is to the left
proximal part is to the right
What happens to the distal part after rotation?
develops a bulb that will become the cecum
what happens to the proximal part after rotation?
becomes convoluted
After the ab cavity becomes large enough which part comes back in first?
proximal part
it passes under the distal part and to the left making a 90 degree turn
what does the distal part do when it comes back in the ab cavity?
makes a 90 degree turn counterclockwise
what is the total turn ins in the midgut?
270 degrees counter clockwise
