Anatomical terminology

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 deep inguinal lymph node. The function of the femoral canal is to accommodate the distension of the femoral vein when venous return from the leg is increased or temporarily restricted (e.g. during a Valsalva maneuver).[1]

The proximal, abdominal end of the femoral canal forms the femoral ring.[1]

The femoral canal should not be confused with the nearby adductor canal.
