19928. Anatomical terminology. [edit on Wikidata] The inguinal canal is a passage in the anterior abdominal wall on each side of the body (one on each side of the midline), which in males, convey the spermatic cords and in females, the round ligament of the uterus. The inguinal canals are larger and more prominent in males.
Structures passing behind the inguinal ligament. Anterolateral view of the right side of the pelvis. The inguinal ligament (/ ˈɪŋɡwɪnəl / [1][2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an ...
The pubic tubercle is a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis bone. The inguinal ligament attaches to it. [1] Part of the abdominal external oblique muscle inserts onto it. [1] The inferior epigastric artery passes between the pubic tubercle and the anterior superior ...
The pectineal ligament is strong, and holds suture well. [citation needed] This facilitates reconstruction of the floor of the inguinal canal. [citation needed] It is a useful landmark for pelvic surgery. [1] A variant of non-prosthetic inguinal hernia repair, first used by Georg Lotheissen in Austria, now bears his name. [citation needed]
The conjoint tendon is formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle. [1] It inserts into the pubic crest and the pectineal line immediately behind the superficial inguinal ring. [1] It is usually conjoint with the tendon of the internal oblique muscle, but ...
The lacunar ligament is the part of the aponeurosis of the external oblique muscle that is reflected backward and laterally and is attached to the pectineal line of the pubis. It is about 1.25 cm. long, larger in the male than in the female, almost horizontal in direction in the erect posture, and of a triangular form with the base directed ...
The femoral triangle is bounded: [2] superiorly (also known as the base) by the inguinal ligament. [2]medially by the medial border of the adductor longus muscle. (Some people consider the femoral triangle to be smaller hence the medial border being at the lateral border of the adductor longus muscle.) [2]
Its fibers run perpendicular to the external oblique muscle, beginning in the thoracolumbar fascia of the lower back, the anterior 2/3 of the iliac crest (upper part of hip bone) and the lateral half of the inguinal ligament. The muscle fibers run from these points superomedially (up and towards midline) to the muscle's insertions on the ...
