Q

What is the function of the pelvic floor?

A
  • Closes the abdominal cavity
  • Supports pelvic organs
  • Contributes to continence
  • Contributes to childbirth
2
Q

Name the muscles which form the pelvic diaphragm:

A
Coccygeus
Levator ani:
 - Puborectalis
 - Pubococcygeus
 - Iliococcygeus
3
Q

The anterior perineum is described as a ‘triangular sandwich’. Which structures form this sandwich?

A
  • Fascia

  • Perineal membrane
4
Q

If the urethra ruptures beneath the perineal membrane, where will urine collect?

A

Superficial perineal pouch

5
Q

What is the arterial supply to the pelvic floor?

A
  • Pudendal A’s
  • Vaginal A’s

6
Q

Which nerves innervate the pelvic floor?

A

Pudendal nerves

S2, 3, 4, keep your guts off the floor

7
Q

How does the pelvic floor help maintain rectal continence?

A

Sphincter mechanism of puborectalis maintains angle ~ 80’ between rectum and anus

8
Q

Describe the location of the perineal body:

A
  • @ midpoint of line joining ischial tuberosities

@ junction of anterior and posterior perineum

9

  • Malnutrition
  • Previous pelvic surgery
  • Increased intra-abdominal pressure
  • Chronic constipation
11
Q

Why are people with Ehlers-Danlos syndrome at increased risk of pelvic organ prolapse?

A

Intrinsic connective tissue laxity due to defects in collagen formation

12
Q

How can a midline tear (and potential damage to anal sphincter) be avoided during childbirth?

A

Episiotomy

= Mediolateral cut 45-60’ to R side of vagina

13
Q

Pelvic floor exercises - ‘kegel exercises’

14
Q

What are some side effects of continence/prolapse surgery?
