Exam 3 - Anterior and Medial Thigh Flashcards
When the external iliac artery goes under the inguinal ligament, it becomes:
The femoral artery
Which vein passes anterior to the medial malleolus (ankle bone) ?
Great saphenous vein
Incompetent valves result in?
Varicose veins
The small saphenous vein drains into the ___ vein.
Popliteal vein (behind knee)
When a resident has trouble finding veins for an IV, they might use what vein?
Great saphenous vein for a “saphenous cutdown”
The great saphenous vein empties most of the blood into the _____ vein after piercing the opening in fascia lata.
femoral vein
Where does the small saphenous vein ascend?
Posterior to lateral malleolus
The superficial nodes drain everything in the lower limb except for the ______.
testes - these drain to lumbar nodes
The deep inguinal nodes are found right along the side of the _______.
femoral vein
The iliotibial tract, a thickening of fascia lata, receives insertions of what two muscles?
- Tensor fascia-lata
2. 2/3 of the gluteus maximus
What is the longest muscle in the human body?
Sartorius - flexes & laterally rotates thigh @ hip joint
flexes & medially rotates thigh @ knee joint
Which part of the quadriceps flexes the femur at the hip joint?
Rectus femoris
Iliopsoas serves what functions?
Chief flexor of thigh (at hip joint)
Stabilizes the lumbar portion of the vertebral column in the sitting position
The ____ nerve is the nerve of the adductor compartment.
Obturator nerve
Two muscles fused to form the adductor magnus in the medial compartment of the thigh. What is the function of the Hamstring portion?
The hamstring portion extends the femur. Like all hamstring muscles, it has an attachment on the ischial tuberosity.
What is the nerve supply of the adductor magnus?
Adductor portion: Obturator nerve
Hamstring portion: Tibial division of sciatic nerve
Which hamstring muscle crosses only 1 joint?
The hamstring portion of the adductor magnus only crosses 1 joint. All others cross two joints.
What are the contents of the femoral triangle from lateral to medial?
Lateral: femoral nerve
then: femoral SHEATH
Medial: deep inguinal nodes (within sheath)
What are the contents of the femoral sheath from alteral to medial?
Lateral: femoral artery
then: femoral vein
medial: femoral canal
What is the medial boundary of the femoral canal?
Lacunar ligament
Instead of passing through the superficial inguinal ring (as in inguinal hernias), in femoral hernias the intestine slips BELOW the __________ ligament and is deep to the fascia lata.
Inguinal
The contents of the adductor canal include what four structures?
Femoral artery
Femoral vein
Nerve to vastus medialis
Saphenous nerve
What structure runs down instead of passing into the popliteal fossa?
The saphenous nerve - which provides the cutaneous supply to the medial leg. It runs with the great saphenous vein.
From outside to inside, which muscles are supplied by the obturator nerve in the anteromedial femoral thigh?
Abductor longus
Abductor brevis
Abductor magnus
