The pectineal line of the pubis (also pecten pubis) is a ridge on the superior ramus of the pubic bone. It forms part of the pelvic brim. Lying across from the pectineal line are fibers of the pectineal ligament, and the proximal origin of the pectineus muscle. [1] In combination with the arcuate line, it makes the iliopectineal line.

The pectineal ligament, sometimes known as the inguinal ligament of Cooper, is an extension of the lacunar ligament. It runs on the pectineal line of the pubic bone . The pectineal ligament is the posterior border of the femoral ring .

The pectinate line (dentate line) is a line which divides the upper two-thirds and lower third of the anal canal. Developmentally, this line represents the hindgut - proctodeum junction. It is an important anatomical landmark in humans, and forms the boundary between the anal canal and the rectum according to the anatomic definition. [ 1 ]
The obturator foramen is situated inferior and somewhat anterior to the acetabulum.It is bounded by the pubis bone and the ischium: superiorly by the (grooved obturator surface) of the superior ramus of pubis, inferiorly by the ramus of ischium, and laterally by (the anterior edge of) the body of ischium (including by the margin of the acetabulum).
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 .
It ends anteriorly in a broad aponeurosis (the Spigelian fascia), the lower fibers of which curve inferomedially (medially and downward), and are inserted, together with those of the internal oblique muscle, into the crest of the pubis and pectineal line, forming the inguinal conjoint tendon also called the aponeurotic falx.
