the ampulla in the uterine tube/fallopian tube is where fertilization takes place and is possible for ectopic pregnancy to occur

9

describe anteflexed vs anterverted

  • anteflexed (bent forward): uterine body in relation to cervix
  • anteverted (turned forward): cervix in relation to vagina

10

Q image thumb

The arrows in the circle show how there is an open connection between the fimbria of the uterine tubes/fallopian tubes and the peritoneal cavity

any infection in the tract can spread to the peritoneal cavity

11

since the pelvic organs extend into the abdominal cavity, they are covered by ______

the fold of _____ over the uterus forms the ____ _____ that "drapes" over the uterus and tubes

since the pelvic organs extend into the abdominal cavity, they are covered by peritoneum

the fold of peritoneum over the uterus forms the broad ligament that "drapes" over the uterus and tubes

12

the cervical ligaments are condensations of ____ _____ extending;

anteriorly: _____

lateral: _____

posterior: ______

the cervical ligaments are condensations of pelvic fascia extending;

anteriorly: pubocervical 

lateral: transverse cervical/cardinal (uterine a. and v. lie within)

posterior: uterosacral

13

describe the relationship between the rectum and vagina

the posterior wall of the vagina is closely associated with the anterior wall of the rectum forming the rectovaginal septum

any tear in this septum makes a connection between the 2

14

describe a uterine prolapse (procidentia)

  • due to loss of support by the cardinal/uterosacral/pubocervical ligaments and by levator ani

15

the _____ is the lowest point in the abdominopelvic cavity in the upright position

a _____ can sample this fluid 

the rectouterine pouch (pouch of Douglas) is the lowest point in the abdominopelvic cavity in the upright position

 

a culdocentesis can sample this fluid 

16

with the exception of the ____, all pelvic viscera are supplied by branches of the _____ arteries 

with the exception of the ovaries, all pelvic viscera are supplied by branches of the internal iliac arteries

gives rise to ____ _____ and _____ arteries 

the internal pudendal artery exits pelvis through greater sciatic foramen with pudendal nerve

enters the lesser sciatic foramen to pass anteriorly through the ischiorectal fossa to finally reach the perineum

gives rise to inferior rectal and perineal arteries 

18

lymphatics

upper (proximal) vagina drains to internal iliac nodes

lower vagina drain into superficial inguinal (horizontal) 

19

explain what happens above the PPL 

  • above PPL = uterine tubes and uterine body
    • the visceral afferents for pain travel via the sympathetics
      • ​they travel in the inferior hypogastric plexus
      • pain is referred to the T10-L1 areas

20

describe what happens below the PPL

  • below PPL = lower portion of the cervix, urinary bladder, upper portion of vagina and large intestine after the middle of the sigmoid colon
    • the visceral afferents for pain travel via the parasympathetics (come from pelvic spanchnic nerves)

21

the lower 1/4 of the vagina has somatic pain fibers that travel via pudendal nerve 

22

it expands to form the _____ before joining the duct of the ____ _____ to form the ______

the ductus deferens passes in the spermatic cord through the inguinal canal towards the posterior aspect of the bladder

it expands to form the ampulla before joining the duct of the seminal vesical to form the ejaculatory duct

23
