The pectineal line is a bony ridge located on the posterior surface of the pubis bone in the human pelvis. It serves as an important anatomical landmark, marking the boundary between the pubic crest and the pectineus muscle. This line plays a role in the attachment of various muscles and ligaments, contributing to pelvic stability and movement. In addition to its anatomical significance, the pectineal line is also relevant in medical imaging and surgical procedures involving the pelvis. Understanding its location helps healthcare professionals accurately assess pelvic conditions and plan interventions, ensuring better patient outcomes.
