Reproductive Flashcards
Pelvic splanchnic nerves
(presynaptic) Parasympathetic
Merge with the hypogastric nerves
Pelvic pain line
course of visceral pain sensation
Structures ABOVE demonstrate sympathetic pelvic splanchic nerves
Structures BELOW inferior peritoneum convey parasympathetic pelvic splanchic nerves
Pelvic Arteries
(that enter the lesser pelvis)
- Internal iliac arteries
1.A anterior division provides visceral branches (to ORGANS)2.B Posterior division provides parietal branches to (CONNECTIVE TISSUE) or parietal branches
*these are both branches off the common iliac
- Testicular or Ovarian Arteries
- Median sacral artery
- Superior Rectal A
Pelvic Veins
Drained mainly by the internal iliac veins
- superior rectal veins
- Median sacral vein
- Gonadal veins
- Internal vertebral venous plexus
Ureters pass over pelvic brim @…
the height of bifurcation of common ilaic arteries
they pass inferiomedially to bladder
ADD
ADD
Ductus Deferens
Seminal Glands
Prostate
fibrous capsule of the prostate that encapsulates the nerves and veins
Penis
three erectile cavernous tissue:
1. corpora cavernosa x2
2. corpus spongiosum ventrally
fibrous outer covering or capsule – tunica albuginea
Vagina vasculature
uterine artery (supplies the superior portion of the vagina)
ADD
Skene’s Glands
Paraurethral glands
a pair of glands that lubricates external genitalia
Bartholin’s Glands
vulvovaginal glands
- on either side of vagina
ADD
Vulva
External pudental artery
internal pudental artery
- supplies skin, external genitalia, and ADD
Uterus
ligament of ovary (attaches posterior inferior)
round ligament of the uterus (attaches anterior inferiorly)
broad ligament of uterus (double layer of peritoneum, extends to lateral walls and floor of pelvis)
- keeps uterus centered and contains ovaries, uterine tubes and their vasculature
Suspensory ligament of ovary (superiorly over the ovary)
Uterine Tubes
- interstital / intramural
- Isthmus – narrowest portion
- Ampulla (middle widest part / site for fertilization)
- Infundibulum has fimbriae
Rectum
rectosigmoid function is at level of S3
rectum ends at anteriorinferior to the tip of coccyx where rectum becomes the anal canal
Ampulla of the rectum is the dilated terminal part for retaining feces
ADD
ADD
Blood supply to rectum
superior rectal artery (innervates proximal part)
middle rectal arteries
inferior rectal arteries (arrise from the internal pudenal arteries)
ADD
ADD
Venous drainage of rectum
submucosal rectal venous plexus surrounds the rectum and communcates with the vesical venous plexus in males
and uterovaginal venous plexis in females
Pudendal canal
horizontal passageway in the obturator fascia
- lesser sciatic notch to the ischial spine
bifurcation gives rise to
1. perineal nerve and artery
2. dorsal artery of penis or cliterous (sensory nerve)
Breast tissue
