The parts are best studied from the abdominal side, and for this purpose we shall suppose in the first place that peritoneum, subperitoneal fat, transversalis fascia, and other structures have been removed, leaving the bones, ligaments, and muscles exposed, and that the abdominal wall is viewed from behind. Poupart's ligament is a strong fibrous band, which runs from the anterior superior spine to the spine of the pubes. Gimbernat's ligament is a reflection from its inner, or pubic Fig 21 -Stereogram of Abdominal Wall, giving an Exaggerated 'view of the Inguinal, Femoral, and Obturator Canals, (tor references, see Fig. 22.)

They rise from Poupart, arch over, and then, fusing to form the conjoined tendon, pass almost directly doNvnwards, to be inserted into [a] the crest of the pubes, in front of the rectus
