1
iliopsoas
**consists of psoas major and iliacus
2
attachments of psoas major
origin:
anterior surfaces of bodies and transverse processes of last thoracic (T12) and all lumbar vertebrae
insertion:
lesser trochanter of femur
3
innervation of psoas major
ventral rami spinal nerves L1,2,3
4
action of psoas major
flexes and laterally rotates thigh
5
attachment of iliacus
origin:
iliac fossa
insertion:
with psoas major to lesser trochanter
6
action of iliacus
flexion and lateral rotation of thigh
7
innervation of iliacus
femoral nerve
-L2,3
8
attachments of sartorious
origin:
ASIS
insertion:
medial tibial below condyle with gracilis and semitendinosus muscles at pes anserinus
9
action of sartorious
flexes leg and rotates it medially
flexes thigh and rotates laterally
abducts lower limb when knee locked
10
innervation of sartorious
femoral nerve
11
muscles of quadriceps femoris?
rectus femoris
vastus lateralis
vastus medialis
vastus intermedialis
12
attachments of rectus femoris?
origin:
straight head - AIIS
reflected head - superior brim of acetabulum
insertion:
superior surface of patella; to tibial tuberosity via patellar ligament
13
action of rectus femoris?
flexion of thigh
extension of leg
14
innervation of rectus femoris
femoral nerve
15
attachments of vastus lateralis
origin:
anterolateral surface of most of femur
insertion:
lateral border of patella; to tibial tuberosity via patellar ligament
16
action of vastus lateralis
extension of leg
17
innervation of vastus lateralis
femoral nerve
18
attachments of vastus medialis
origin:
anteromedial surface of most of femur
insertion:
medial border of patella; to tibial tuberosity via patellar ligament
19
action of vastus medialis
extension of leg; assists in maintaining proper patellar tracking
20
innervation of vastus medialis
femoral nerve
21
attachments of vastus intermedius
origin:
most of anterior surface of femur
insertion:
deep surface of tendon of rectus femoris and other vastus muscles via aponeurosis
22
action of vastus intermedius
extension of leg
23
innervation of vastus intermedius
femoral nerve
24
attachments of articularis genu
origin:
lower anterior surface of femur
insertion:
upper portion of synovial membrane of knee joint
25
action of articularis genu
prevents synovial membrane from becoming trapped between patella and femur when leg extended
26
innervation of articularis genu
femoral nerve
27
anterior femoral muscles?
psoas major
iliacus
sartorius
rectus femoris
vastus lateralis
vastus intermedius
vastus medialis
articular genu
28
muscles of medial femoral compartment?
pectinus
adductor longus
adductor brevis
adductor magnus
gracilis
obturator externus
29
attachments of pectinus?
origin:
superior pubic ramus
insertion:
posterior femur below lesser trochanter (pectineal line of femur)
