Name 5 functions of the pelvis
1. Cradles and protects the reproductive organs
2. Absorbs and dissipates the ground reaction
force as it transfers from the feet to the pelvis
when walking or running
3. Offers attachment for the lower limbs
4. Transfers weight of the trunk onto the legs
5. Takes the weight of the sitting body
2
Name the four bones of the pelvis
Two innominate bones (hip bones)
One sacrum
One coccyx
3
The 2 innominate bones are joined together anteriorly by which joint?
Symphysis pubis
4
Which 2 joints connect the innominate bones to the sacrum?
Sacroiliac joints
5
Name the joint which connects the coccyx to the sacrum?
Sacrococcygeal joint
6
The 2 innominate bones are each formed by the fusion of 3 bones around the acetabulum. What is the acetabulum?
The socket of the hip bone
7
Which part of the pubic bone are the levator ani attached to?
The inner surface of the pubic bone
8
How many fused vertebrae make up the sacrum?
Five
9
Which lumber vertebra does the sacrum articulate with?
Last lumbar vertebrae
10
The sacroiliac joint is described as being a synovial joint. What does this mean?
Joints lubricated with synovial fluid, cushion the joints and allow free movement
11
The coccyx is composed of 4 small fused vertebrae. Which of the following muscles are not attached to the coccyx?
a) Bulbocavernosus
b) Rectus abdominus
c) Pubococcygeus
d) Transverse perineal
e) Iliococcygeus
Bulbocavernous
12
Name the FIVE pelvic joints which are held together by ligaments
Interpubic ligaments at the symphysis pubis
Sacroiliac ligaments
Sacrococcygeal ligaments
Sacrotuberous
Sacrospinous
13
Name the EIGHT points of the pelvic brim
Starting at the back and moving clockwise:
Sacreal Promontory
Sacreal Ala
Sacroiliac Joint
Iliopectinial Line
Iliopectinial Eminence

Anteroposterior
Transverse
Right Oblique
Left Oblique
Anteroposterior - Sacrum to Pubic Bone (11cm)

15
What forms the anterior wall of the pelvic cavity?
The pubic bone and symphysis pubis
16
What forms the posterior wall of the pelvic cavity?
