bony protrusion on medial side of bones distal end

22
Q

lateral epicondyle of femur

A

gives attachment to fibular collateral ligament of knee joint

23
Q

intercondylar notch

A

deep notch between the rear surfaces of the medial and lateral epicondyle of the femur; 2 protrusions on distal end of the femur that joins the knee

24
Q

tibial plateau of tibia and fibula

A

made up of condyle

25
Q

medial condyle of tibia and fibula

A

upper surface of tibia (medial portion)

26
Q

intercondylar eminence of tibia and fibula

A

just into intercondylar notch

27

lateral condyle of tibia and fibula

A

lateral portion of the upper extremity of tibia

28
Q

medial malleous of tibia and fibula

A

prominence of the inner side of the ankle, formed by the lower end of the tibia

29
Q

lateral malleous of tibia and fibula

A

prominence in the outer side of ankle, formed by lower end of the fibula

30
Q

anterior of the thigh

A

femoral nerve (L2-L4)

31
Q

posterior of the thigh

A

sciatic nerve (L4-S3)

32
Q

medial of the thigh

A

obturator nerve (L2-L4)

33
Q

anterior of the leg

A

deep fibular nerve

34
Q

posterior of the leg

A

tibial nerve

35
Q

lateral of the leg

A

superficial fibular nerve

36
Q

lumbosacral plexus

A

formed by the anterior divisions of the lumbar nerves, sacral nerves, and coccygeal nerves to supply the lower limbs

37
Q

femoral nerve

A

largest branch of the lumbar plexus; comes out from the intervertebral foramen to make way from the pelvis to innervate the anterior compartment of the thigh (L2-L4)

38
Q

obturator nerve

A

passes out from pelvis from the obturator foramen to innervate the medial compartment of the thigh (L2-L4)

39
Q

sciatic nerve

A

innervates the posterior compartment of the thigh from the greater sciatic foramen of the gluteal region (L4-S3)

40
Q

the sciatic nerve splits into the…

A

tibial nerve and common fibular nerve to supply the leg

41
Q

tibial nerve

A

sciatic nerve continues as the tibial nerve in the posterior compartment of the leg, innervates the muscles of that compartment

42
Q

fibular nerve

A

branches off of the sciatic nerve and wraps around the neck of the fibula to split into the superficial and deep branches

43
Q

superficial fibular nerve

A

innervates later compartments of the leg

44
Q

deep fibular nerve

A

innervates the anterior compartment of the leg

45
Q

sources for blood supply to the lower limbs

A

1)aorta, 2)common illiac a, 3)external illiac a, 4)femoral a, (deep arteries of the thigh) 5)medial/6)lateral circumflex femoral a

46
Q

(1) the femoral artery…

A

passes through the adductor hiatus and becomes the “popliteal artery” on the posterior side of the knee

47
Q

(2) then splits into the…

A

anterior and posterior tibial arteries

48
Q

(3) the anterior tibial artery…

A

passes between the tibia and fibula to the anterior side of the leg

49
Q

(4) the posterior tibial artery…

A

continues on the posterior side of the leg

50
Q

(5) the fibular artery…

A

branches laterally off of the posterior tibial artery
