Week 2 Flashcards
Meckels diverticulum
- sxs
- asymptomatic
- complications from obstruction ectopic tissue, or inflammation
Ompholocele
- sxs
- US detection of intestine outside abdominal cavity covered with a membrane
- defect in the wall of the abdomen and the intestine doesn’t return to the abdomen
Gastroschisis
- sxs
- US detection of uncovered intestines outside of abdominal cavity
- peritoneum stays inside and the intestines are outside
esophageal atresia
- sxs
- cause
- kinds
- drolling and substantial mucus, difficulty maintaining airway when drinking
- tracheal/esophageal fistula that needs to be repaired or there is gonna be resp pneumonia occurring
- atresia with proximal fistula
- atresia with distal fistula
- atersia with double fistula
pyloric stenosis
- sxs
- non-bilious vomiting and regurg, can be projectile, leaves child still hungry
- sphincter wasn’t engineered correctly and it lead to pyloric stenosis
volvulus
lop of intestine trwists around itself and the messentary that supports it resulting in obstruction
rectal atresia
- unconnected rectal and anal canal
impeforate
failure of cloacal membrane to break down
anal agenesis
anal canal ends as blind sac below puborectalis muscle
proctodeum
- invagination of surface of endoderm that forms the lower anal canal
anorectal agensis usualy w/ 1 of 3 fistulas
rectum ends as blind sac above puborectalis muscle because pf abnormal formation of urorectal septum
ventral pancreatic bud
form most of the head and uncinate process of the pancreas
annular pancreas
d the wrong way around the duodenum and give rise to duodenal atresia/obstruction
hematopoesis
begins in the liver by week 6
origin of the liver, gallbladder and biliary apparatus
hepatic diverticulum
where do the cystic and bile ducts come from?
the stalk of the hepatic diverticulum
Obliteration of bile ducts
is the most common form of extra biliary atresia
Septum transversum
forms central tendon of diaphragm and is a sheet of splanchnic mesoderm
where does the uncinate of the process come from? the rest of the pancres?
- ventral pancreatic duct
- dorsal
cloaca
- pouch that will perforate to give rise to the inferior rectum and anal canal
allantois
acts as a primitive kidney in early development
vitelline duct
attachment area where the midgut would be developing and eventually coming out of the body
Meckel’s dive
unobliterated vitelline duct having to do w/ the midgut
