Flashcards in 11 - Repro - Pelvic floor Deck (14):
1

What is the function of the pelvic floor?

- Closes the abdominal cavity
- Supports pelvic organs
- Contributes to continence
- Contributes to childbirth

2

Name the muscles which form the pelvic diaphragm:

Coccygeus
Levator ani:
- Puborectalis
- Pubococcygeus
- Iliococcygeus

3

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

- Fascia
- Sphincter urethrae
- Perineal membrane

4

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

Superficial perineal pouch

5

What is the arterial supply to the pelvic floor?

- Pudendal A's
- Vaginal A's
- Inferior Rectal A's

6

Which nerves innervate the pelvic floor?

Pudendal nerves

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

7

How does the pelvic floor help maintain rectal continence?

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

8

Describe the location of the perineal body:

- @ midpoint of line joining ischial tuberosities
(@ junction of anterior and posterior perineum)

9

Which structures attach to the perineal body?

- Anal sphincters
- Bulbospongiosus
- Superficial transverse perineal muscles
- Levator ani

10

List some risk factors for pelvic floor dysfunction (ie incontinence/prolapse):

- Age
- Childbirth
- Menopause
- Obesity
- Chronic cough
- Intrinsic connective tissue laxity
- Malnutrition
- Previous pelvic surgery
- Increased intra-abdominal pressure
- Chronic constipation

11

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

Intrinsic connective tissue laxity due to defects in collagen formation

12

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

Episiotomy
= Mediolateral cut 45-60' to R side of vagina

13

Name a safe, easy, non-invasive treatment for pelvic floor dysfunction:

Pelvic floor exercises - 'kegel exercises'

14

What are some side effects of continence/prolapse surgery?

- Recurrence
- Voiding difficulty
- New incontinence
- Dyspareunia
