female gu exam 3 Flashcards
what is included in the vulva?
mons pubis, labia majora, labia minora, clitoris, vestibule, skenes glands, bartholins glands, urethral meatus, vaginal introitus
fourchette
formed by inferior union of labia minora at posterior commissure
perineum
located between fourchette and anus
hymen
circular fold of tissue that may partially or completely occlude vaginal introitus
labia majora
rounded folds of adipose and connective tissue
extends from the mons to just pass the posterior commissures
labia minora
thinner, medial, pink red flods that extend anteriorly to form prepuce and clitoris
prepuce
female foreskin
innervation of the clitoris
dorsal nerve branches off the pudendal nerve to innervate
average length and width of clitoris and adult female
width= ~1 cm
length= 1.5-2 cm
what does the vestibule contain?
the urethral meatus and opening to the skene’s glands bilaterally
vaginal introitus
opening to the vagina, contains the hymen
site of episiotomy or tears during childbirth
perineum
if skenes glands are edematous or tender you should consider
infection- chlamydia or ghonorrhea
bartholins gland function
secrete watery fluid that serves as lubricant during intercours
cystocele
when the wall between the bladder and the vagina weakens
bladder falls through vaginal introitus
retrocele
wall between rectum and vagina weakens
rectum falls through vaginal introitus
uterine prolapse
Prolapse of the uterus results from weakness of the supporting structures of the pelvic floor and is often associated with a cystocele and rectocele. In progressive stages, the uterus becomes retroverted and descends down the vaginal canal to the outsid
vulva nerve innervation
pudendal nerve
-innervates majority of vulva
-responsible for proper functioning and control of urination defecation and orgasm
ilioinguinal and genitofemoral nerve
-innervate anterior to urethra
blood supply of vulva
predominately from internal pudendal arteries
where does the cervix turn into the uterus?
at the isthmus
what is the lining of the uterus called?
endometrium
*endometrial lining 2-10 cm thick depending on stage of menstrual cycle
length of vagina
~7-10 cm
length of cervix
~3 cm
muscle layers of the vagina
-inner circular muscle layer
-outer logitudinal smooth muscle layer
vaginal cells responsible for resistance to infection
superficial cells of vagina that contain glycogen which produce lactic acid with normal vaginal flora
what tissue lines the vagina?
stratified squamous epithelium
