Question 21

leg
posterior tibial:

Answer 21

posterior leg, continues to lateral and medial plantar arteries

Question 22

deep veins of lower limbs

Answer 22

the same as arteries

Question 23

superficial veins of lower limb

Answer 23

-great saphenous vein: pre-axial comp. medial side of ankle.ascends anterior to medial malleolus and drains into the femoral artery.
-small saphenous vein: post axial comp, posterior midline. ascends posterior to lateral malleolus and drains into popliteal artery

Question 24

superficial vein
great saphenous vein

Answer 24

ascends anterior to medial malleolus and drains into the femoral vein

Question 25

superficial vein
small saphenous vein

Answer 25

ascends posterior to the lateral malleolus and empties into the popliteal vain

Question 26

sciatica

Answer 26

lower back pain caused by a herniated dick in the lower back that pinches nerve roots, prior to sciatic nerve proper being formed

Question 27

Answer 28

iliofemoral
pubofemoral
ischiofermoral

Question 29

medial circumflex artery

Answer 29

supplies most of the blood to the head and neck of the femur

Question 30

knee joint

Answer 30

bicondylar hinge joint
flexion, extension, medial, and lateral rotation
composed: femur, tibia, and patella

Question 31

what stabilizes the knee joint

Answer 31

patellar ligament: flex and extend
fibular and collateral ligaments: FCL LCC
cruciate ligament: anterior and posterior ACL PCL

Question 32

menisci of knee joint

Answer 32

medial and lateral crescent plates of fibrocartilage

Question 33

anterior cruciate ligament:

Answer 33

ACL
prevents posterior displacement of the femur on the tibia and hyperextension of the knee joint

Question 34

posterior cruciate ligament

Answer 34

PCL
prevents anterior displacement of the femur on the tibia or posterior displacement of the tibia on the femur, prevents hyperflexion of knee joint
