1

What separates the major and minor pelvis?

Superior pelvic aperture / pelvic brim

2

Major route of communication between pelvic cavity and lower limb

Greater sciatic foramen

3

Prior to puberty, the ilium, ischium, and pubis are three separate bones connected by:

Triradiate cartilage

4

T/F: The greater sciatic foramen serves as the entry point of neurovascular structures to the abdominal cavity

F. It serves as the exit. The lesser sciatic foramen is the entry point

5

In obstetrics, the most important pelvic diameter measured is:

Anteroposterior, because it is the shortest diameter

6

Most adequate diagonal conjugate for childbirth

Greater than or equal to 11.5 cm

7

Boundaries of the pelvic outlet

Anterior: pubic symphysis
Posterior: sacrum, coccyx
Lateral: ischial tuberosity

8

The normal female pelvic type is termed:

Gynecoid – pelvic inlet is rounded, oval shape, transverse diameter is wide

9

What muscle makes up most of the lateral pelvic wall?

Obturator internus

10

Largest muscle in the pelvic floor

Levator ani

11

Part of the levator ani that forms a muscular sling around the anorectal junction

Puborectalis

12

During childbirth, what is the most likely muscle to be injured? Why?

Pubococcygeus, because of its proximity to the uterus

13

In females, what are the two potential spaces in the pelvic area?

Vesicouterine: between bladder and uterus

Retrouterine / pouch of Douglas: between rectum and uterus

14

Serves as a bed for the sacral and coccygeal plexuses

Piriformis

15

Main nerve of perineum and chief sensory nerve of external genitalia

Pudendal nerve

16

T/F: The inferior gluteal nerve supplies both the gluteus maximus and the gluteus minimus

F. The superior gluteal nerve innervates both muscles. The inferior gluteal nerve only innervates gluteus maximus

17

T/F: The superior gluteal artery arises from the posterior division of the internal iliac artery

T

18

The artery supplying the ductus deferens and prostate originates from where?

inferior vesicular artery

19

The pelvic girdle is composed of:

1. Innominate bones – ilium, ischium, pubis
2. Sacrum and coccyx

20

Dimples at buttocks are at the level of:

PSIS

21

When in a sitting position, a person is resting on his/her ________

Ischial tuberosity

22

Attachment of the inguinal ligament in the pelvis

Pubic tubercle

23

Sharp oblique ridge at the lateral part of the superior pubic ramus

Pectineal line / pecten pubis

24

The pubic arch is formed by:

Ischiopubic rami of both sides of the pelvis

25

How many longitudinal crests are on the dorsal part of the sacrum

5

26

Median sacral crest is formed from:

Fused spinous processes

27

Intermediate sacral crest is formed from:

Fused articular processes

28

Lateral sacral crest is formed from:

Fused transverse processes

29

`The coccyx is formed from the fusion of how many rudimentary vertebrae

4

30

Strongest ligament in the body

Sacroiliac ligament
