Embryology of Urinary & Reproductive Systems Flashcards
intermediate mesoderm gives rise to _
large portions of the urinary and genitalia systems
kidney caudal sequence
pronephros –> mesonephros –> metanephros
mesonephros
forms functional renal corpsucles and tubules that connect with the mesonephric duct (Wolffian)
metanephros
forms the permanent kidney
gonads develop on _
medial side of mesonephros
paramesonephric (Mullerian) duct develops _
parallel to mesonephric duct
collecting structures are all from _
ureteric bud
nephrons develop from _
metanephric mesoderm
ureteric bud gives rise to _
ureter, pelvises, and collecting ducts
gonads are anchored by _
gubernaculum
pelvic kidney
kidney that did not ascend to correct position; adrenal gland will still be in correct position because they develop apart from one another
horseshoe kidney
two kidneys fuse together during ascension; can not ascend further than inferior mesenteric artery
mesonephric duct will ultimately empty into _
urethra
ureteric duct will ultimately empty into _
bladder
allantois
extension from apex of forming bladder to the umbilicus; also known as urachus
urachal fistula
if allantois remains open, can connect bladder and umbilicus and urine can drain into umbilical area
