    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

Q

Name the four bones of the pelvis

A

Two innominate bones (hip bones)
One sacrum
One coccyx

3
Q

The 2 innominate bones are joined together anteriorly by which joint?

A

Symphysis pubis

4
Q

Which 2 joints connect the innominate bones to the sacrum?

A

Sacroiliac joints

5
Q

Name the joint which connects the coccyx to the sacrum?

A

Sacrococcygeal joint

6
Q

The 2 innominate bones are each formed by the fusion of 3 bones around the acetabulum. What is the acetabulum?

A

The socket of the hip bone

7
Q

Which part of the pubic bone are the levator ani attached to?

A

The inner surface of the pubic bone

8
Q

How many fused vertebrae make up the sacrum?

A

Five

9
Q

Which lumber vertebra does the sacrum articulate with?

A

Last lumbar vertebrae

10
Q

The sacroiliac joint is described as being a synovial joint. What does this mean?

A

Joints lubricated with synovial fluid, cushion the joints and allow free movement

11
Q

e) Iliococcygeus

A

Bulbocavernous

12
