SDR 1/2 - Urogenital System Flashcards
Pronephros/Mesonephros
Fake kidney
1) Adrenal Medulla (Neuro - Ecto)
2) Genital Swelling/UG Sinus (Endo)
The mesoderm gives rise to all of the genitourinary organs except
Mesonephric (Wolffian) Duct
This develops into the male parts + trigone
Paramesonephric (Mullerian) Duct
This develops into the female parts
Metanephros
Real kidney
Ureteric Duct
This develops into the ureter and collecting system
Mesonephric duct
The ureteric duct arises from the
Cloaca
This early structure is a common chamber into which urinary, genital and gastrointestinal tracts converge
Urogenital Sinus
This structurs is the site of genitourinary development from the bladder down (excluding gonads and their tubing). It is the ventral part of the cloaca, formed after it separates the anal/urogenital canal during the 4th to 7th weeks of development
Oligohydramnios
Decreased amount of amniotic fluid. Often a sign that the fetus is not producing urine
IMA
A horseshoe kidney is most commonly caught on this artery while ascending
Mesonephron
This structure acts as a premature kidney for the 1st trimester. Then it disappears to give rise to something else (next card)
1) Trigone
2) Efferent ducts of testis
3) Epididymus
4) Vas Deferens
The mesonephron gives rise to the mesonephric duct after ~1st trimester. What 4 structures does the mesonephric duct differentiate into
T
(T/F) All kidneys develop from the intermediate mesoderm
4
Pronephros = gone after week ~____
8
The Metanephros becomes the functional kidney after ~____ weeks
1) Ejaculatory Duct/Prostatic Urethra
2) Lower 1/3 of Vagina/Urethra
In males the UG Sinus/Cloaca develop into the (1), and in females they develop into the (2)
1) Ureteric Bud
2) Nephros
The (1) and (2) are best friends. The induce each other to create the kidney and collecting system
DCT
The metanephros makes up the nephron from the glomerulus to the
1) Collecting Ducts
2) Calyces
3) Pelvis
4) Ureter
The Ureteric Bud gives rise to these 4 aspects of the collecting system
1) Cloaca
2) Metanephros
Two insertions of the ureteric bud
MCDK (Multicystic dysplastic kidney)
Most common cause of abdominal mass in a child
Sacrum
The kidney begins in the (1) and rises up to the chest
F (gains/loses blood supply as it rises)
(T/F) As the kidney ascends, it typically brings along its blood supply
