1. Arteries of lower extremity
Superior gluteal artery:
Branch of posterior div. of internal iliac artery
Enters the gluteal region through greater sciatic foramen passing above the piriformis.
In the foramen it divides into superficial & deep branches.
Superficial branch supplies gluteus max.
Deep branch subdivides into sup. & inf. branches

2. Arteries of gluteal region
Inferior gluteal artery
Branch of ant. Div. of internal iliac artery
Enters gluteal region by passing through greter sciatic foramen below the piriformis.
It Supplies
Musular branches
Cutaneous branches to buttock & back of thigh
Articular branch to hip joint
Artery to sciatic nerve
Cruciate anastamotic branch
Coccygeal branch

3. Arteries of gluteal region
Internal pudendal artery
Branch of ant. Div of internal iliac artey
Enters gluteal region through greater sciatic foramen

4. Trochanteric anastomosis
This anastomosis is a channel of communication between internal iliac and femoral arteries.
Situated near the trochanteric fossa
Supplies branches to head of femur
Inf. Div. of deep branch of sup. Gluteal artery
Ascending branch of medial circumflex femoral artery
Ascending branch of lateral circumflex femoral artery
Often the inf. Gluteal artery

5. Cruciate anastomosis
Situated at the level of lesser trochanter of femur
Formed by
Inferior gluteal artery
Medial femoral circumflex artery
Lateral femoral circumflex artery
First perforating artery, a branch of profunda femoris artery

11. Profunda femoris Largest branch of femoral artery
Main artery of all three compartments of thigh
Arises from lateral side of femoral artery 4cm below the inguinal ligament
Branches:
Medial circumflex femoral artery
Lateral circumflex femoral artery
4 perforating arteries

12. Profunda femoris & its branches

13. Popliteal artery Continuation of femoral artery
Begins at the opening in the adductor magnus
Runs downwards &laterally to reach lower border of popliteus
At that point it terminates by dividing into ant. &post. Tibial arteries
Branches
Muscular : supply adductor magnus & hamstrings ,terminate by anastomosing with 4th perforating artery

14. Popliteal artery Cutaneous: accompany small saphanous vein
Genicular: 5 in number
2 superior: medial & lateral superior genicular arteries
2 inferior: medial & lateral inferior genicular arteries
1 middle

15. Anterior tibial artery
Smaller terminal branch
Passes into ant. Compartment by passing through gap in the upper part of interosseous membrane
Deep in the upper part of course
Supply adjacent muscles
Superficial in the lower part
passes behind the extensor retinaculum, has ext.hallucis longus tendon on its medial side and deep peroneal nerve and extensor digitorum longus on its lateral side
On entering the ankle region it becomes dorsalis pedis artery

16. Anterior tibial artery
Branches
Muscular branches
Anastomotic branches with branches of other arteries around knee and ankle joint
Vanea commitantes of anterior tibial artery joins with those of posterior tibial artery in the popliteal fossa to form popliteal vein

17. Dorsalis pedis artery
It terminates by passing downward into the sole between the two heads of 1st dorsal interosseous muscle
Joins lateral planter artery to form planter arch
Branches
Lateral tarsal artery
Arcuate artery (gives off dorsal metatarsal artery)
1st dorsal metatarsal artery

18. Posterior tibial artery
Branches
Peroneal artery
Muscular branch
Nutrient artery to tibia
Anastomotic branch
circumflex fibular branch
malleolar branch
calcaneal branch
terminal branches
Medial & lateral planter arteries

20. Medial planter artery
gives off muscular to the adjoining muscles
3 small superficial digital branches
lateral planter artery
larger terminal branch
ends at the base of 5th metatarsal bone by continuing with planter arch
branches
1) muscular branches
2)superficial branches supplying skin &
3)anastomotic branches
4) Calcaneal branch

22. Planter arch Formed by direct continuation of lateral planter artery.
Completed medially by dorsalis pedis artery
Extends from base of 5th metatarsal bone to the proximal part of 1st intermetatarsal space
Lies between 3rd & 4th layer of sole
Accompanied by vanea commitantes & deep branch of lateral planter nerve

23. Planter arch Branches 4 planter metatarsal arteries
3 proximal perforating arteries
Communicate with the dorsal metatarsal arteries (branches of arcuate artery)
Distal end of each planter metatarsal artery gives of distal perforating artery
