what can gastroschisis cause

Answer 14

intestinal damage

Question 15

what happens with gastroschisis

Answer 15

body wall closure failure in abominal region, intestinal loops may herniate into amniotic cavity, exposure to amniotic fluid can harm and the intesines may twist around each other

Answer 35

coronary artery

Question 36

the lungs go from back to (what direction)

Answer 36

front

Question 37

what does lung coat itself with as it travels back to front

Answer 37

visceral lateral plate mesoderm

what does lung coat itself with as it travels back to front

Answer 38

visceral lateral plate mesoderm

Question 39

how do you separate pleural and peritoneal cavities

Answer 39

diaphragm

Question 40

why dont lungs go through diaphragm

Answer 40

the rest of the body starts growing faster, so the lungs are pushed up by everything else growing

Question 41

septum transversum

Question 42

what does cdh stad for

Answer 42

congenital diaphragmatic hernia

Question 43

what is bochdalek formed from

Answer 43

posteriolaterl defects of diaphragm (intestines go through diaphram)

Question 44

what is a morgani hernia caused by

Answer 44

anterior midline in xiphoid and ocatl margins

Question 45

why is morgani hernias less severe

Answer 45

it goes through muscle, so the muscle prevents more from going through it

Question 46

a 19 year old man... which is the following is most likely about pericardium? A. all 3 layers of pericardium are derived directly from pleuropericardial folds B. visceral pericardium is innervated by same nerves that innervate the heart C. pleuropericardial folds remain unfused D. defects in pleuropericardial folds result in anterior wall defects E. pericardium is formed by septum only

Answer 46

B
