Female Reproductive Anatomy Flashcards
describe location of ureter
ureter travels under the uterine artery
what is the muscle of the bladder
detrusor
describe contraction and relaxation of the bladder
sympathetic reflexes: Detrusor muscle is RELAXED, and internal urethral sphincter is CONTRACTED, no urination
parasympathetic: detrusor muscle is CONTRACTED and internal urethral sphincter is RELAXED, allows urination
composition of internal urethral sphincter
smooth muscle
composition of external urethral sphincter
skeletal muscle, under somatic control
where is external urethral sphincter located
in the deep perineal space
how are parasympathetics conveyed
pelvic splanchnics and inferior hypogastric plexus
how are sympathetics conveyed
hypogastric plexus
describe bladder when sympathetic innervation
internal urethral sphincter contracts, during ejaculation and “stage fright”
compare male and female urethra
females have short urethras, males have long urethras
describe mons pubis
fatty eminence over pubic symphysis
describe difference between labia majora and minora
majora has sebacous glands, hair, and fat, minora is mostly skin folds with some erectile tissue
describe vestibule
space surrounded by labia minora containing openings of urethra, vagina, and vestibular glands
parts of the clitoris
glans, prepuce, crura
descrive vestibular glands
mucus secreting glands on either side of vestibule in superficial space
describe posterior commissure
overlies the perineal body, “gooch”
what muscles overlie erectile tissue in the superficial pouch
- bulbospongiosus
2. ischiocavernosus
what muscles are in the superficial pouch (males and females)
- bulbospongiosus
- ischiocaveronosus
- superficial transverse perineal
where are the external genitalia rooted?
perineal membrane
where is the crus of clitoris?
bilaterally under the ischiocavernosus muscle along the superior pubic rami
what are the erectile tissues of the female perineum
- crus of clitoris
- body of clitoris
- glans of clitoris
- bulb of the vestibule
what is the glans of clitoris made of
corpus cavernosa
what is the female homologue of the penis
clitoris
what is the female homologue of the glans penis
glans clitoris
what is the female homologue of the corpora cavernosa
corpora covernosa clitoris
what is the female homologue of the corpus spongiosum
bulb of vestibule
what is the female homologue of the ventral penile raphe
labia minora
what is the female homologue of the scrotum
labia majora
what is the female homologue of the gubernaculum testis
ovarian and round ligaments
what is the female homologue of the penis
clitoris
what is the female homologue of the glans penis
glans clitoris
what is the female homologue of the corpora cavernosa
corpora covernosa clitoris
what is the female homologue of the corpus spongiosum
bulb of vestibule
what is the female homologue of the ventral penile raphe
labia minora
what is the female homologue of the scrotum
labia majora
what is the female homologue of the gubernaculum testis
ovarian and round ligaments
2 main peritoneal pouches of the female pelvis
- rectouterine pouch - between uterus and rectum
2. vesicouterine pouch - between bladder and uterus
significance of recouterine pouch
when standing, this is the deepest point of the pelvis, so fluid from ascites can pool here
how to aspirate fluid from recouterine pouch
needle in the posterior fornix of the cervix through vaginal canal
what is the peritoneal covering of the structures in the true pelvis?
broad ligament of the uterus (COVERS ALL)
what connects the ovary to the uterus
ligament of the ovary
what connects the ovary to the pelvic wall
suspensory ligament of the ovary, contains ovarian vessels
innermost part of uterus
myometrium
muscular part of uterus
myometrium
parts of cervix
external os, cervical canal, internal os at the uterine isthmus
vaginal fornices
anterior, posterior, lateral
parts of the uterine tubes
coming from the ovary, fimbriae to infundibulum, to ampulla to isthmus of uterus, to fundus of uterus
vaginal fornices
anterior, posterior, lateral
parts of the uterine tubes
coming from the ovary, fimbriae to infundibulum, to ampulla to isthmus of uterus, to fundus of uterus
what is the position of the uterus relative to vaginal canal and bladder
uterus lays on top of bladder, makes angle of anteversion (anteverted and anteflexed)
what do surgeons ligate when doing a tubal ligation?
fallopian tubes
abnormal positions of the uterus
retroverted or retroflexed or prolapsed
where is the round ligament
from uterus through inguinal canal to labia majora
what ligament connects the cervix to the sacrum
uterosacral ligament
what ligament connects the cervix to the pelvic wall
transverse/cardinal ligament
what is mainly responsible for preventing uterine prolapse
pelvic floor muscles - levator ani
main parts of broad ligament
- mesosalpinx
- mesovarium
- mesometrium
where is mesosalpinx
suspends uterine tube, has tubal branches of uterine artery and vein
where is mesovarium
attaches to ovary and covers ovarian ligament
where is mesometrium
extends from lateral pelvic wall to body of uterus
differentiate ligament of ovary and suspensatory ligament of ovary
suspensatory ligament of ovary connects ovary to lateral pelvic wall and has ovarian vessels in it, ligament of ovary connects ovary to uterus
degrees of uterine prolapse from mild to severe
1, 2, 3rd degree
drainage of lymph from fundus of the uterus
along gonadal vessels straight to para-aortic/lumbar nodes
drainage of lymph from body/cervix of uterus
to pelvic lymph nodes/internal iliac nodes, then common iliac, then lumbar nodes
