61

Inferior borders of pubic arch define the:

subpubic angle

62

Structure covering the obturator canal

obturator membrane

63

Anterior sacrococcygeal joint is held together by:

anterior longitudinal ligament

64

Posterior sacrococcygeal joint is held together by:

posterior longitudinal ligament

65

the sacroilac ligament is supported by which other ligaments?

1. sacrotuberous ligament
2. sacrospinous ligament

66

3 planes through which the head of the baby must exit in childbirth

1. Superior pelvic aperture
2. Pelvic midplane
3. Inferior pelvic aperture

67

the pelvic brim is formed by:

1, promontory and ala of sacrum
2. right and left linea terminalis - arcuate line, pecten pubis, pubic crest

68

continuation of pecten pubis in ilium

arcuate line

69

elevations and depressions on surfaces of ilium and sacrum produce:

interlocking of bones, giving the sacroiliac joint more strength and stability

70

Sacroiliac joint: type of joint

synovial

71

most uncommon pelvic type

platypelloid

72

Components of lateral pelvic wall

1. ilium and ramus of ischium
2. obturator internus muscle

73

Components of posterior pelvic wall

1. sacrum
2. ilium
3. sacroiliac joint
4. piriformis muscle

74

The piriformis exits at the

greater sciatic foramen

75

The obturator internus exits at the

lesser sciatic foramen

76

Piriformis: action

laterally rotate thigh

77

Components of the pelvic floor

1. levator ani
2. coccygeus

78

Membrane that closes the urogenital hiatus

perineal membrane

79

Shape of pelvic diaphragm

hammock-shaped - deeper at the central part, shallower at the end

80

T/F: the pelvic diaphragm is relaxed during forced expiration, coughing, and strong movements of the upper limbs

F, the pelvic diaphragm contracts/tightens during these actions to increase support to the viscera and increase abdominal pressure

81

Major consequence of denervation of levator ani

Fecal and urinary incontinence

82

Likely consequences of pubococcygeal injury

1. uterine prolapse
2. cystocoele
3. rectocoele

83

Cystocoele: definition

bladder wall prolapse

84

Rectocoele: definition

rectal wall prolapse

85

T/F: the entire rectum is covered by peritoneum

F, the inferior third of the rectum does not have a peritoneal covering

86

T/F: the Fallopian tube is not entirely covered by the peritoneum on its posterior aspect

F, the Fallopian tube is entirely enclosed by peritoneum

87

The pelvic peritoneum covers what surfaces of the pelvic viscera?

Superior and lateral surfaces

88

The space between the peritoneum and the pelvic muscles/pelvic floor is covered by

Pelvic fascia

89

Pelvic fascia is a continuation of:

endoabdominal fascia

90

T/F: the entire uterus is mobile to allow for enlargement during pregnancy

F, the cervix of the uterus is an immobile structure
