Nerves, Blood, and Spaces
popliteal artery
behind the knee artery
lateral circumflex femoral artery
blood supply for: upper femur, thigh muscles, knee
adductor hiatus
(gap) between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa.
common peroneal nerve
A division of the sciatic nerve that extends from behind the knee to wind around the head of the fibula to the front of the leg where it divides into two branches.
tibial nerve
A division of the sciatic nerve that passes behind the knee. It subdivides and supplies impulses to the knee, the muscles of the calf, the skin of the leg, and the sole, heel, and underside of the toes.
deep peroneal nerve
Also known as anterior tibial nerve; it extends down the front of the leg, behind the muscles. It supplies impulses to these muscles and also to the muscles and skin on the top of the foot and adjacent sides of the first and second toes.
peroneal artery
Artery that carries oxygenated blood to the little toe side of the lower leg
inferior gluteal artery
Branches off internal iliac artery; exits pelvis through greater sciatic foramen; supplies gluteus maximus
medial plantar artery
Which of the following arteries is one of the bifurcations of the posterior tibial artery?
adductor canal
D
anterior tibial artery
One of the popliteal arteries (the other is the posterior tibial artery) that supplies blood to the lower leg muscles and to the muscles and skin on the top of the foot and adjacent sides of the first and second toes. This artery continues to the foot where it becomes the dorsalis pedis artery.
obturator artery
Origin: Internal Iliac Artery, Course: Passes along lateral pelvic wall to superior part of obturator foramen Passes through obturator canal to reach medial thigh
profunda femoris artery
Origin: femoral artery (largest branch)
popliteal vein
The vein that forms when the anterior and posterior tibial veins unite at the knee.
anterior branch of obturator nerve
This nerve leaves the pelvis in front of the obturator externus and descends in front of the adductor brevis, and behind the pectineus and adductor longus; at the lower border of the latter muscle it communicates with the anterior cutaneous and saphenous branches of the femoral nerve, forming a kind of plexus.
posterior branch of obturator nerve
This nerve pierces the anterior part of the Obturator externus, and supplies this muscle; it then passes behind the Adductor brevis on the front of the Adductor magnus, where it divides into numerous muscular branches which are distributed to the Adductor magnus and the Adductor brevis
posterior tibial artery
artery supplying the foot, behind the medial ankle
dorsalis pedis artery
artery supplying the foot, lateral to the large tendon of the big toe
small saphenous vein
empties into the popliteal vein posterior
femoral triangle
inguinal ligament, sartorius, adductor longus
femoral nerve
innervates quadriceps and skin of anterior thigh and medial surface of leg
superior gluteal artery
largest branch of the internal iliac artery and supplies the gluteus medius
great saphenous vein
longest vein in the body, travels along medial leg; empties into the femoral vein
femoral vein
major vein of the thigh that receives blood from the deep femoral and great saphenous vein
obturator nerve
passes through obturator foramen to innervate adductor muscles
internal pudendal artery
perineum and external genitalia
superficial peroneal nerve
peroneus longus, peroneus brevis
femoral artery
the major artery supplying the leg
Sartorius, adductor longus/magnus and vastus lateralis
these muscles pass through the adductor canal
medial circumflex femoral artery
upper femur, thigh muscles blood supply
