- flexion
- extension
- lateral flexion
Attachments of the lateral lumbosacral ligament
from the lower border of transverse process of L5
to the ala of sacrum
Function of the lateral lumbosacral ligament

to the ischial spine
Attachments of: superior pubic ligament
between both pubic crests and tubercles
Attachments of: inferior pubic ligament
between the pubic rami
Functions of the: anterior sacroiliac ligament
essential in childbirth
Functions of the: posterior sacroiliac ligament
limits anterior rotation and forwards/downwards movement of sacrum
Functions of the: interosseous sacroiliac ligament
keep the sacrum and ilium tightly secured
Functions of the: sacrotuberous and sacrospinous ligaments
resist posterior rotation of sacrum
