The femoral ring is the opening at the proximal, abdominal end of the
femoral canal,
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.
