Q

abductors of the hip

A

gluteus medius and minimus, piriformis, oburator internus and superior and inferior gemelli

24
Q

which obturator muscle adducts the hip

A

obturator externus

25
Q

innervation of hip abductors

A

gluteus medius and minimus –> superior gluteal nerve
piriformis –> S1-S2
obturator internus –> nerve to obturator internus (L5-S1)
superior gemelli –> nerve to obturator internus (L5-S1)
inferior gemelli –> nerve to quadratus femoris (L5-S1)

26
Q

order to gluteal region muscles from top to bottom

A

maximus –> medius –> minimus –> piriformis –> superior gemelli –> obturator internus –> inferior gemelli –> quadratus femoris

27
Q

true/false - there is no abductor compartment of the hip

A

true - deep gluteal muscles have this role

28
Q

attachment of all abductor muscles

A

greater trochanter of the femur

29
Q

which muscles of the opposite limb are active in supporting the leg being lifted

A

abductors

30
Q

internal (medial) rotators of the hip

A

gluteus medius, gluteus minimus and tensor fasciae latae

31
Q

external (lateral) rotators of the hip

A

gluteus maximus, piriformis, superior and inferior gemelli, obturator internus, quadratus femoris and sartorius

32
Q

gluteus maximus medially/laterally rotates the hip

A

laterally rotates the hip

33
Q

gluteus medius medially/laterally rotates the hip

A

medially rotates the hip

34
Q

gluteus minimus medially/laterally rotates the hip

A

medially rotates the hip

35
Q

3 compartments of the thigh

A

anterior, medial and posterior

36
Q

muscles compartments that act on the hip

A

anterior, medial and posterior thigh and gluteal region

37
Q

distal attachment of patellar ligament

A

tibial tuberosity

38
Q

4 actions of the sartorius

A

flexion, abduction and lateral rotation of hip

flexion of knee

39
Q

attachments of sartorius

A

ASIS to superior medial tibial surface

40
Q

how come the sartorius can produce flexion at both knee and hip

A

because it spirals around the leg from lateral to medial

41
Q

medial thigh muscles (adductor group)

A

adductor longus, brevis and magnus, obturator externus and gracilis

42
Q

innervation of medial thigh muscles

A

all obturator nerve EXCEPT hamstring part of adductor magnus which is from tibial part of sciatic nerve

43
Q

through which foramen does the obturator nerve enter the thigh

A

obturator foramen

44
Q

which muscle’s distal attachment to the femur forms the adductor hiatus

A

adductor magnus

45
Q

structures that pass through the adductor hiatus

A

femoral artery and vein

46
Q

adductor brevis lies deep/superficial to the adductor longus

A

deep

47
Q

femoral artery is a continuation of what artery

A

external iliac

48
Q

landmark of external iliac becoming femoral artery

A

inguinal ligament

49
Q

surface marking of inguinal ligament

A

between the ASIS and pubic tubercle

50
Q

large branch of the femoral artery which passes posteriorly to the hamstrings

A

profunda femoris artery

51
Q

femoral vein is a continuation of what vein

A

popliteal

52
Q

femoral vein becomes what vessel past the inguinal ligament

A

external iliac vein

53
Q

3 veins in the femoral triangel

A

profunda femoris, great saphenous and femoral veins

54
Q

what is the largest branch of the lumbar plexus

A

the femoral nerve

55
Q

4 muscles in what compartment are supplied by the femoral nerve

A

anterior compartment - sartorius, iliacus, pectineus and quatriceps femoris
