Anatomy: Blood Vessels and Lymphatics of the Lower Limb Flashcards
What is the arcuate artery?
Branch of dorsalis pedis that supplies the dorsum of the foot
Where does the small saphenous vein drain into?
Popliteal vein (within popliteal fossa)
The medial and lateral plantar arteries are branches of which artery?
Posterior tibial artery
Name the main deep venous structure of the foot
Dorsal venous arch
Where do the digital arteries arise from?
Metatarsal arteries
How many digital arteries are there per toe?
4
What does the fibular artery supply?
Lateral compartment of the leg
The popliteal artery is a continuation of which artery?
Femoral artery
Where does lymph following the small saphenous vein drain into?
Popliteal lymph nodes, which then drain into deep inguinal lymph nodes
Name the arteries of the foot
Dorsalis pedis, medial and lateral plantar, metatarsal, digital
Name the main artery of the lower limb
Femoral artery
Name the superficial veins of the lower limb
Great saphenous vein, small saphenous vein
Where can the femoral artery be palpated?
In the femoral triangle, 2-3 cm inferior to the midpoint of the inguinal ligament
Where does the great saphenous vein arise from?
Medial aspect of the dorsal venous arch of the foot
Name the deep veins of the gluteal region
Inferior and superior gluteal veins
Where does the great saphenous vein drain into?
Femoral vein
Where does the small saphenous vein arise from?
Lateral aspect of the dorsal venous arch of the foot
The fibular artery is a branch of which other artery?
Posterior tibial artery
How does the femoral vein leave the thigh?
Runs underneath the inguinal ligament - becomes the external iliac vein
Fractures occuring at the neck of the femur are in danger of severing which artery?
Medial femoral circumflex artery
What does the anterior tibial artery supply?
Pierces the interosseous membrane to supply the anterior compartment of the leg
What do the perforating branches of profounda femoris supply?
Perforate the adductor magnus, contributing to the supply of the muscles in the medial and posterior thigh
Name the three main branches of the profound femoris artery
Perforating branches, lateral femoral circumflex artery, medial femoral circumflex artery
Where does lymph following the great saphenous vein drain into?
Superficial inguinal lymph nodes, which drains into external iliac nodes and deep inguinal nodes
What does lymph from superficial structures follow?
Great and small saphenous veins
Name the deep veins of the foot and leg
Dorsal venous arch, medial and lateral plantar veins, anterior and posterior tibial veins, fibular vein, popliteal vein
Where do the metatarsal arteries arise from?
Deep plantar arch and the arcuate artery
Why should no adrenaline-containing local anaethetic should be used be used near the digital arteries?
The digital arteries are end arteries
Name the veins which form the popliteal vein
Anterior tibial, posterior tibial and fibular veins
Where can dorsalis pedis artery be palpated?
Lateral to extensor hallucis longus tendon
What do the medial and lateral circumflex arteries supply?
Supply the majority of blood to the head of the femur through their retinacular branches
All lymph from the lower limb ultimately drains into which node?
External iliac nodes
Where does the popliteal artery divide into the anterior and posterior tibial arteries?
Immediately distal to the popliteal fossa
Dorsalis pedis artery is a branch of which artery?
Anterior tibial artery
The femoral vein is a continuation of which vein?
Once the popliteal vein has entered the thigh, it is known as the femoral vein
The femoral artery is a continuation of which artery?
External iliac
Where are the deep inguinal lymph nodes located?
Deep to the deep fascia of the thigh (fascia lata) medial to the femoral vein
What does the posterior tibial artery supply?
Posterior compartment of the leg
Supplies the foot via branches - terminates by dividing into the medial and lateral planter arteries
Where does the profounda femoris artery arise from?
The posterolateral aspect of the femoral artery
