32
tensor fasciae latae innervation and supply
superior gluteal nerve L4-5, superior gluteal arteries and lateral circumflex femoral artery
33
sartorius muscle inserts into the
superior portion of medial surface of the tibial shaft close to the insertion of gracilis and semitendinosus
34
sartorius action
flexor, abductor and lateral rotator of thigh at hip joint , also flexes leg at knee joint and balances pelvis
35
what is the longest muscle in the body and why ?
sartorius muscle as it crosses two joints
36
rectus femoris function
flexes the thigh but extends the leg
37
origin of the psoas muscle
all five of the lumbar vertebrae T12-L5
38
iliopsoas insertion
lesser trochanter of the femur
39
iliopsoas function
flexing the trunk against gravity
40
psoas function

41
innervation of psoas muscle
anterior rami L1-L3
42
psoas blood supply
lumbar braches of iliolumbar artery
43
iliacus origin
inner wing of the ilium / iliac fossa
44
iliacus function
flexor of the thigh and flexor of the trunk ipsilaterally
45
iliacus innervation
femoral nerve L2-L4
46
iliacus blood supply
iliac branches of the iliolumbar artery and medial circumflex femoral artery
47
tensor fascia latae origin
anterior superior iliac spine and anterior portion of the iliac crest
48
tensor fascia latae action

sartorius innervation and blood supply
femoral nerve L2-L3, femoral artery
54
sartorius is the ... muscle in the body
longest
55
sartorius crosses which two joints
crosses hip joint anteriorly and knee joint posteriorly therefore can flex both

vastus' insertion
into the quadricep tendon
63
vastus lateralis is the ... of the quadricep muscles
largest
64
vastus intermedius origin
anterior and lateral aspects of the femoral shaft
65
vastus medialis origin
