1

2

Label the 5 parts of the ischium

See image

3

Label the 4 parts of the pubis

See image

4

Label the 11 parts of the hip bone from an internal view

See image

5

Label the 8 parts of the sacrum and coccyx

6

Describe the orientation of the pelvis

  • ASIS and pubic tubercle in same vertical plane
  • Tip of coccyx and pubic symphisys in the same horizontal plane
  • Ischial tuberosity is what you sit on

7

Define the greater (false) pelvis and the lesser (true) pelvis

Greater = above the pelvic inlet

Lesser = within the confines of the pelvic inlet and outlet

8

Define the boundaries of the pelvic outlet (3)

  • Pubic symphysis
  • Ischial tuberosities
  • Coccyx

9

Define the boundaries of the pelvic inlet (5)

  • Ala of the sacrum
  • Arcuate line
  • Pectineal line
  • Pubic symphysis
  • Sacral promontory

10

Difference between false pelvis of male and female

  • Female = wide and shallow
  • Male = narrow and deep

11

Difference between male and female pelvic inlet

  • Female = transversely oval
  • Male = heart-shaped

12

Difference between male and female pelvic outlet

  • Female = roomy and round
  • Male = narrow and oblong

13

Difference between male and female ischial tuberosities

Female = everted

Male = inverted

14

Difference between male and female pelvic cavity

  • Female = roomy and shallow
  • Male = narrow and deep

15

DIfference between male and female sacrum

  • Female = short, wide and flat
  • Male = long, narrow and convex

16

Difference between female and male subpubic angle

Female = 90 - 100 degrees

Male = 70 degrees

17

Label the 5 anterior ligaments of the pelvis

See image

18

Label the 3 posterior ligaments of the pelvis

See image

19

Foramena formed by the sacrospinous and sacrotuberous ligaments

  • Greater sciatic foramen
  • Lesser sciatic foramen

20

Function of sacrospinous and sacrotuberous ligaments

Prevent upward tilting of the lower end of the sacrum by anchoring it to the ischium

21

Location of piriformis muscle

From the anterolateral surface of the sacrum - out the greater sciatic foramen - to the greater trochanter of the femur

22

Location of the obturator internus muscle

From the obturator membrane and surrounding bone - out the lesser sciatic foramen - to the greater trochanter of the femur (red lines)
