  • surrounds the urethra
  • inferior to the bladder
  • posterior to the pubic symphysis and anterior to rectum
34
Q

Uterus

Uterine Tubes

Ovaries

Pair of greater vestibular glands

36
Q

Uterus

A
  • located between bladder and rectum
  • divided into:

  • female who has not given birth

1/2 corpus and 1/2 cervix

38
Q

Parous

A
  • female who has given birth

2/3 corpus

1/3 cervix

39
Q

Anteverted

A
  • normal position of the uterus
  • tipped anteriorly relative to the axis of the vagina
40
Q

Anteflexed

A
  • normal position of the uterus
  • bent anteriorly relative to the axis of the cervix so it rests on the bladder
41
Q

Retroverted

A
  • uterus that is tilted posteriorly relative to the axis of the vagina
42
Q

Retroflexed

A
  • uterus whose fundus is pointing posteriorly so that angle relative to cervix is increased
43
Q

Round Ligament

A
  • passes through the deep inguinal ring
  • travels in the inguinal canal and terminates in the labia majora
  • continous with the proper ligament of the ovary where they fuse on the lateral wall of the uterus
44
Q

A

Fimbriae - projections off of the infandibulum that catch the egg

  • fascial condensation in female

Supports:

  • urethra, bladder, and cervix (important for urinary continence)

A
  • anchors the cervix laterally to the pelvis
  • uterine vessels travel through
56
Q

Uterosacral Ligament

A
  • anchors the cervix and uterus to the sacrum
57
Q
A
58
Q

Puboprostatic Ligament

A
  • endopelvic fascia condensation
  • anchors prostate to public bone
59
Q

Sacrogenital Ligament

A
  • endopelvic fascial condensation in male
  • anchors prostate to sacrum
60
Q

Exception to “Subperitoneal”

A
  • most organs in the pelvis are below the peritoneum

Exception = uterus - has a mesentery and is intraperitoneal

61
Q

Rectovesical Pouch

A
  • recess formed by the reflection of the peritoneum over the bladder and the rectum in the male
62
Q

Pararectal Fossae

A
  • spaces along the lateral aspects of the rectum (male and female)
63
Q

Vesicouterine Pouch

A
  • shallow recess between the bladder and the uterus
64
Q

Rectouterine Pouch (of Douglas)

A
  • deep recess between the uterus and the rectum (adjacent to the posterior fornnix of the vagina)
  • when supine, lowest portion of the abdominopelvic cavity - site where infection and fluids often collect
65
Q

Broad Ligament of the Uterus

A
  • double layer of peritoneum
  • extends from the sides of the uterus to the lateral walls/floor of the pelvis

Three Parts:

Mesometrium (body of uterus to body walls)

Mesosalpinx (surrounds uterine tubes)

66
Q

Proper Ligament of the Ovary
