posterior tibial recurrent a.
what does the posterior tibial recurrent a. anastomose with?
inferior genicular branches to take part in the genicular anastomoses
what % of the time does the circumflex fibular arise from the anterior tibial a.? what about from the posterior tibial a.?
from anterior tibial a. - 40%
from posteiror tibial a.- 32%
what are the branches of the posterior tibial artery?
- muscular
- peroneal artery
- nutrient artery to the tibia

posterior tibial artery supplies what muscular branches?
to FHL, peroneus longus and brevis, tibialis posterior and soleus muscles
what are the deep veins of the leg?
- posterior tibial
- anterior tibial
- popliteal
what are the superficial veins of the leg?
- small (lesser) saphenous vein
- great saphenous vein
how many valves does the great saphenous? and lesser saphenous vein have?
great saphenous vein- 10 to 20 valves
small saphenous vein- 9 to 12 valves
Where do the lymphatic vessels of the leg drain into?
anterior tibial lymph node
popliteal lymph node
Where does the anterior tibial node receive lymph from?
anterior tibial vessels
the anterior tibial node sends efferents to where?
popliteal lymph nodes
where do superficial lymph vessels that course with the great saphenous vein drain into?
superficial inguinal nodes
Where do lymphatics that course with the small saphenous vein drain into?
popliteal nodes
Where do the deep lymphatic vessels of the dorsalis pedis and anterior tibial drain?
anterior tibial nodes
where do the deep lymphatic vessels of the medial and lateral plantar drain?
popliteal
where do the deep lymphatic vessels of posterior tibial and peroneal drain?
popliteal
where do the deep lymphatic vessels of the femoral and deep femoral drain?
deep inguinal
In the popliteal fossa, describe the relationship of the popliteal artery to other structures.
anteriorly- it lies against the capsule of the joint
posteriorly- it is deep to the semimembranosus muscle, popliteal vein, tibial nerve, and gastrocnemius muscle
Name teh 10 branches of the popliteal artery.
- cutaneous
- muscular
- medial superior genicular
- lateral superior genicular
- medial inferior genicular
- lateral inferior genicular
- middle genicular
- posterior tibial
- anterior tibial
- sural (medial & lateral)
How many genicular arteries are give off by the popliteal artery to supply the knee joint?
5: medial/lateral superior genicular & medial/lateral inferior genicular & middle genicular
What do the medial and lateral sural arteries supply?
gastrocnemius, soleus, and plantaris muscles
cutaneous branches of the popliteal artery supply what?
superficial structures of the posterior part of the leg
muscular branches of the popliteal artery supply what?
addcutor magnus and hamstring muscles
what do the medial and lateral superior genicular arteries supply?
they wind around the superior aspect of the femoral condyles and reach the anterior side of the knee to help form the collateral circulation around the knee
what does the middle genicular artery supply?
enters the knee joint to supply the ACL and PCL
what does the medial and lateral inferior genicular arteries supply?
passes below MCL to supply the tibia and the knee joint
*the lateral infeior genicular a. travels laterally superior to the head of the fibula
what vessels take part in the genicular anastomosis?
- descending genicular artery
- medial and lateral superior genicular arteries
- medial and lateral inferieor genicular arteries
- descending branch of the lateral femoral circumflex a.
- anterior and posterior tibial recurrent a.
- circumflex fibular a.
where does the anterior tibial artery begin and end?
begins at the inferior border of the popliteus muscle and ends at the ankle joint, midway btwn the medial and lateral malleoli where it becomes the dorsalis pedis artery
What does the circumflex fibular artery supply?
(br. of anterior tibial a.)
ramifies around the neck of the fibula to supply the soleus and peroneus longus
describe the course of the peroneal arery.
(largest br. of the posterior tibial a.) takes origin from the posterior tibial a. about 2cm distal to the inferior border of the popliteus muscle and travels inferiorly along the medial side of the fibula.
what branches does the peroneal artery give off?
lateral calcaneal branches and
posterior lateral malleolar branches
what is one of the 1st branches of the posterior tibial artery?
nutrient artery to the tibia that enters the nutrient foramen
(originates just inferior to the bifuracation of the popliteal)
where do the posterior medial malleolar and posterior lateral malleolar arteries arise from?
posterior medial malleolar a. (from posterior tibial a.)
posterior lateral malleol a. (from peroneal a.)
what does teh communicating branch off posterior tibial a. connect?
travels laterally deep to the FHL to join with the communicating branch of the peroneal a.
