The inguinal ligament (/ ˈ ɪ ŋ ɡ w ɪ n ə l / [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 indirect inguinal hernia may develop.
The presence of swollen inguinal lymph nodes is an important clinical sign because lymphadenopathy (swelling) may indicate an infection, or spread as a metastasis from cancers, such as anal cancer and vulvar cancer. Inguinal lymph nodes may normally be up to 2 cm. [1] The cut-off value for normal sized inguinal nodes is up to 10 mm. [6]
Left and right inguinal regions shown in lower part of diagram. In human anatomy, the groin, also known as the inguinal region or iliac region, [1] is the junctional area between the torso and the thigh. [2] The groin is at the front of the body on either side of the pubic tubercle, where the lower part of the abdominal wall meets the thigh.
Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left.
The superficial inguinal ring (subcutaneous inguinal ring or external inguinal ring) is an anatomical structure in the anterior wall of the mammalian abdomen. It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve , the genital branch of the genitofemoral nerve , and the spermatic cord (in men ...
The reflected inguinal ligament (triangular fascia) is a layer of tendinous fibers of a triangular shape, formed by an expansion from the lacunar ligament and the inferior crus of the subcutaneous inguinal ring.
It provides attachment for the inguinal ligament, the sartorius muscle, [1] [4] and the tensor fasciae latae muscle. [2] [3] A variety of structures lie close to the anterior superior iliac spine, including the subcostal nerve, [5] the femoral artery (which passes between it and the pubic symphysis), [4] and the iliohypogastric nerve. [6]
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]
