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)

30

action of pectineus?

adduction, flexion, assists in rotation of thigh
