🔵the veins of the lower limbs: ------

⏩1--Veins Superficial veins Deep veins
⏩2--Great saphenous vein (long saphenous vein)
⏩3--Short saphenous vein (small saphenous vein)
⏩4--Popliteal vein

⏩5--Femoral vein
⏩6--External iliac vein.

🔵Origin :
°➡️Continuation of the medial marginal vein of the foot (medial end of the dorsal venous arch).

°➡️Continuation of the lateral marginal vein of the foot (lateral end of the dorsal venous arch).

➡️Formed by the union of anterior tibial, posterior tibial, and fibular veins at the inferior border of the popliteus....

°➡️Continuation of the popliteal vein at the adductor hiatus.
°➡️Continuation of the femoral vein posterior to the inguinal ligament...

--⏩Course :
At the ankle: passes in front of the medial malleolus.

⏩--In the leg: ascends along the medial aspect of the shin..
⏩At the knee: runs behind the medial condyles of the femur and tibia ..

⏩Thigh: medial aspect of the thigh.
⏩At the ankle: passes behind the lateral malleolus..

⏩In the leg: ascends in the midline of the calf towards the popliteal fossa
Exits the popliteal fossa superiorly and ascends through the adductor hiatus...

⏩⬆️Begins at the adductor hiatus and accompanies the femoral artery throughout its.. course
Continues as the external iliac vein as it passes posterior to the inguinal ligament...
⏩Begins at the inferior margin of the inguinal ligament..

🔄Continues anteriorly towards the sacrum, where it joins with the internal iliac vein....

⏩Termination
Saphenofemoral junction (SFJ)
The site at which the long saphenous vein passes through the saphenous opening in the deep fascia of the thigh to meet the femoral vein..

The position is fairly constant at 4 cm inferolateral to the pubic tubercle.
Saphenopopliteal junction (SPJ)
The site at which the short saphenous vein drains into the popliteal vein

Unlike the SFJ, the location of the SPJ is variable, lying within, proximal, or distal to the popliteal fossa.

___At the adductor hiatus, continues as the femoral vein…

Posterior to the inguinal ligament, continues as the external iliac vein

➡️At the sacroiliac joint, forms the common iliac vein...
.

🚫🔵Main tributaries ::
1--Short saphenous vein
2--Superficial external pudendal vein
3--Superficial epigastric veins
4---Superficial circumflex iliac vein
5---Lateral femoral cutaneous vein
6--Dorsal vein of the 5th toe
7---Dorsal venous arch
8--Long saphenous vein

🔵🔵Deep vein of the thigh:
1&2Medial and lateral circumflex femoral veins

3--Inferior epigastric vein
4--Deep circumflex iliac vein

⬆️⏩Pubic vein
Drains :
1---The anteromedial aspect of the sole, leg, and thigh
2--The posterior and lower leg

3--The leg, pubic area, and anterior abdominal wall

🔀Important relations
The saphenous nerve accompanies the long saphenous vein below the knee.
The sural nerve accompanies the short saphenous vein through most of its course.

🔀The popliteal artery and popliteal nerve travel with the popliteal vein.
Runs within the femoral triangle
The internal iliac artery is found laterally.
