Corpus: Inguinal ligament

The inguinal ligament extends from the anterior superior iliac spine to the pubic tubercle of the pubic bone.

The inguinal ligament is a strong and taut cord of connective tissue derived from the lower edge of the aponeuroses of the abdominal muscles, specifically the obliquus externus, obliquus internus, and transversus abdominis muscles. It also incorporates transverse fibers from the iliac fascia.

Structurally, the ligament is curved inward like a gutter, forming the anterior and inferior wall of the inguinal canal. Below the ligament lie two significant spaces: the vascular compartment, which allows the passage of blood vessels, and the muscular compartment, through which muscles pass. Additionally, the anterior fibers of the fascia lata originate from the inguinal ligament.
