The femoral ring is the opening at the proximal, abdominal end of the
femoral canal
The femoral canal is the medial (and smallest) compartment of the three compartments of the femoral sheath. It is conical in shape. The femoral canal contains lymphatic vessels, and adipose and loose connective tissue, as well as - sometimes - a ...

and represents the (superiorly directed/oriented
) base of the conically-shaped femoral canal.
The femoral ring is oval-shaped,
with its long diameter being directed transversely and measuring about 1.25 cm.''
'' The opening of the femoral ring is filled in by extraperitoneal fat, forming the
femoral septum Femoral can refer to:
*Having to do with the femur
*Femoral artery
* Femoral intercourse
*Femoral nerve
* Femoral triangle
*Femoral vein

Part of the
intestine can sometimes pass through the femoral ring into the femoral canal causing a
femoral hernia
Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through a naturally occurring weakness in the abdominal wall called the femoral canal. Femoral hernias are a relatively uncommon type, accounting for only 3% of ...

Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position prov ...
by the
pectineal ligament
The pectineal ligament, sometimes known as the inguinal ligament of Cooper, is an extension of the lacunar ligament. It runs on the pectineal line of the pubic bone. The pectineal ligament is the posterior border of the femoral ring.

medially by the crescentic base of the
lacunar ligament
The lacunar ligament, also named Gimbernat’s ligament, is a ligament in the inguinal region. It connects the inguinal ligament to the pectineal ligament, near the point where they both insert on the pubic tubercle.

laterally by the fibrous septum on the medial side of the
femoral vein
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. It ends a ...
