Saphenous opening
Encyclopedia
The saphenous opening is an oval opening in the superomedial part of the fascia lata
, lies 3–4 cm inferolateral to the pubic tubercle. It is about 3 cm long and 1.5 cm wide.
•Covered by a thin perforated part of the superficial fascia called the cribriform fascia (pierced by the great saphenous vein, the 3 superficial branches of the femoral A., and lymphatics).
It transmits the great saphenous vein
and other smaller vessels (like superficial epigastric artery
and superficial external pudendal artery
), as well as the femoral branch of the genitofemoral nerve
.
The cribriform fascia, which is pierced by the structures passing through the opening, closes the aperture and must be removed to expose it.
Fascia lata
-Thickness:It is an investment for the whole of the thigh, but varies in thickness in different parts.Thus, it is thicker in the upper and lateral part of the thigh, where it receives a fibrous expansion from the Glutæus maximus, and where the Tensor fasciæ latæ is inserted between its layers; it...

Great saphenous vein
The great saphenous vein , also long saphenous vein, is the large superficial vein of the leg and thigh.The terms "safaina" and "el safin" have both been claimed as the origin for the word "saphenous."-Path:The GSV originates from where the dorsal vein of the first digit...

Superficial epigastric artery
The superficial epigastric artery arises from the front of the femoral artery about 1 cm below the inguinal ligament, and, passing through the femoral sheath and the fascia cribrosa, turns upward in front of the inguinal ligament, and ascends between the two layers of the superficial fascia of the...

Superficial external pudendal artery
The superficial external pudendal artery arises from the medial side of the femoral artery, close to the superficial epigastric artery and superficial iliac circumflex artery.-Course and target:...

Genitofemoral nerve
In human anatomy, the genitofemoral nerve originates from the upper part of the lumbar plexus of spinal nerves. Its roots are L1 and L2 .The genitofemoral nerve is responsible for both the efferent and afferent limbs of the cremasteric reflex...
