PELVIS/PERINEUM- post mid-term Flashcards
Abnorm. urehral openings on ventral surface of penis
hypospadias
If infant is passing urine near anus instead of tip of penis whats the problem?
Scrotal hypospadias
failure of fusion of labioscrotal folds- involved in formed external urethral orifice only
scrotal or perineal hypospadias
failure of fusion of urethral fold
penile hypospadias
formed from endoderm of cloaca and ectoderm of procotodeum and forms future anus
cloacal membrane
abnorm urethral openings on dorsal side of penis- failure of fusion of what? results from? forms?
epispadias
- spongy urethra
- results from genital tubercle dev more dorsally during development
- forms primordial phallus
normally fuse along ventral side of penis to form spongy urethra
urogenital folds
bounded by urogenital folds and ruptures to form urogenital orifice
urogenital membrane
most anorectal anomalies result from? which results in?
abnorm dev of urogenital septum
- results in non division of cloaca into urogenital and anorectal parts
common outlets of intestinal, urinary, and reproductive tracts- specifically associated with?
persistent cloaca
What form primordial of seminiferous tubules?
seminiferous cords
approach each other and fuse to form scrotum?
Labiocsrotal swellings
condition in which urinary bladder mucosa is open tot he outside in the fetus or newborn? this results from?
extrophy of the bladder
- results from failure of primitive streak mesoderm to migrate around cloacal membrane and often occurs in combo w/ epispadias
Androgens are responsible for development of?
testes
condition where male has 47 XXY chromosomes
Klinfelter syndrome
persistent allantois is associated with?
patent urachus and an allantoic cyst
bifid ureters or paired unilateral ureters result from?
partial or complete division of ureteric bud/metanephric diverticulum
ureteric bud or metanephric diverticulum is an outgrowth from? it is the primordial of what?
the mesonephric duct
- ureter, renal pelvis, calyces, and collecting tubules
incomplete division of ureteric bud results in?
divided kidney w/ bifid ureter
comlpete division of ureteric bud results in?
double kidney w/ bifid ureter or separate ureters
A break or tear in the rectovaginal septum (fascia of Denonvilliers) can allow rectum to herniate into posterior vaginal wall, even to point of protrusion through vaginal introits- whats this called? Name if small intestine herniates thru?
- Rectocele
- enterocele
