Pecten or pectineal line
Other Terms: Iliopectineal line, Pectineal line, Pectineal line of pubis, Pecten ossis pubis, Pecten du pubis, Ligne pectinée
The pectineal line is the sharp ridge-like line on the superior border of the superior ramus. It projects laterally from the pubic tubercle to the iliopubic eminence. This line defines the anterior rim of the pelvic inlet, separating the true and false pelves. It provides attachment for the lacunar ligament, conjoint tendon, pectineal ligament, pectineus muscle, and psoas minor muscle.
Pecten is the Latin term meaning comb. Anciently, anatomists used the term to describe the pubic bone. The pubis may have initially been called the pecten because the two rami of the bone resemble the prongs of a comb.
