ilium, ischium, and pubis
48
hip bones are posteriorly attached to the sacrum by which kind of joint
sacroiliac joints
49
the most prominent landmark of the ilium and can be easily palpated
iliac crest
50
a noticeable bump that serves as the attachment for the inguinal ligament
anterior superior iliac spine
51
tough band that stretches to the pubis and creates a protected passageway for the neurovascular structures passing from the pelvis to the lower limb
inguinal ligament
52
joins the pubis with the ilium
superior pubic ramus
53
joins the pubis with the ischium
