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
