pelvic emryology

what male structures arise form the mesonephric (wolffian) ducts

forms ducts that connect to testes to urethra

• rete testis

• efferent ductules

• epididymis

• vas deferens

• seminal vesicles

• ejaculatory ducts

what female structures arise form the mesonephric (wolffian) ducts

this degenerates and leaves some small remnants

what male structures arise form the paramesonephric (mullerian) ducts

this degenerates and leaves small remnants that contributes to form the prostatic utricle in the prostatic urethra 

what female structures arise form the paramesonephric (mullerian) ducts

• uterus 

• uterine tubes 

• cervix 

• superior 2/3 of vaginal canal 

what develops into the ovaries and testes

gonads

where are the gonads located when they are first formed

high in the posterior abdominal wall near the kidneys

where do the gonads migrate to during fetal development if they are testes

descend through the inguinal canal into the scrotum, guided by the gubernaculum

where do the gonads migrate to during fetal development if they are ovaries

descend into the pelvic cavity, are attaches by the suspensory ligament if the ovary and gubernaculum

what are the 5 homologous embryonic orings between the male and female external genitalia 

• genital tibercle/phallus 

• urogenital folds

• labioscrotal folds

• indifferent gonad

• gubernaculum

what female structures arise from the genital tubercle/phallus

clitoris: 

• glans clitoris 

• corpora cavernosa clitoridis  

• bulb of vestibule

what male structures arise from the genital tubercle/phallus

penis:

• glans penis 

• corpora cavernosum penis 

• corpus spongiosum penis 

what female structures arise from the urogenital folds

• labia minora 

• perineal raphe 

• perianal tissue

what male structures arise from the urogenital folds

• ventral aspect of penis 

• most of penile urethra 

• perineal raphse 

• perianal tissue 

what female structures arise from the labioscrotal folds 

labia majora 

what male structures arise from the labioscrotal folds 

scrotum

what female structures arise from the indifferent gonad

• ovary: follicles form secondary sec cords in cortex

• vestigial: rete ovarii in medulla

what male structures arise from the indifferent gonad

• testis: seminferous tubules form primary sec cords 

• rete testis in medulla 

what female structures arise from the gubernaculum

• ovarian ligament

• round ligament of the uterus

what male structures arise from the gubernaculum

gubernaculum testis
