ABSTRACT
A number of lower limb muscles originate from the bony pelvis. Of the anterior femoral muscles, sartorius and tensor fascia lata originate from the anterior superior iliac spine (ASIS) while the straight head of rectus femoris arises from the anterior inferior iliac spine (AIIS). The adductor muscles including gracillis and pectineus arise from the pubic bone. The largest of these, adductor magnus, also takes origin from the ischiopubic ramus and the ischial tuberosity. The three hamstrings also arise from the ischial tuberosity. The ASIS and AIIS both have accessory ossification centres which appear at puberty and fuse at around 25 years.
