The pecten pubis (a.k.a. pectineal line) is the sharp upper border of the superior pubic ramus. It starts behind the pubic tubercle and extends laterally behind the iliopubic eminence, merging with the arcuate line of the ilium.
Together, the arcuate and pectineal lines are collectively known as the iliopectineal line. When combined with other structures such as the sacral promontory, ala of the sacrum, pubic crest, and pubic symphysis, they form the linea terminalis. The linea terminalis of the right and left sides together constitute the pelvic brim or pelvic inlet.

The iliopectineal line is the border of the iliopubic eminence. [1] It can be defined as a compound structure of the arcuate line (from the ilium) and pectineal line (from the pubis). With the sacral promontory, it makes up the linea terminalis. [2]
These bones are bound together at the sacroiliac joints, and at the symphysis pubis anteriorly. The brim is outlined by the promontory of the sacrum, the sacral alae, the ilio- pectineal lines and the symphysis.
