Vastus intermedius

6

Hip Flexors - Iliopsoas

Iliacus attachments

Iliac crest, fossa, ala of sacrum, anterior sacroiliac ligament to the psoas tendon and lesser trochanter

7

Hip Flexors - Iliopsoas

Iliacus innervation

Femoral nerve (L2,3)

8

Hip Flexors - Iliopsoas

Iliacus function

Flexes hip

9

Hip Flexors - Iliopsoas

T12-L5, IV discs, lumbar transverse processes to the lesser trochanter

10

Hip Flexors - Iliopsoas

Psoas major innervation

Anterior rami L1-3

11

Hip Flexors - Iliopsoas

Psoas major function

Flex hip

12

Hip Flexors - Pectineus

Attachments

Superior ramus of pubis to the pectineal line of the femur

13

Hip Flexors - Pectineus

Innervation

Femoral nerve (L2,3) occasionally a branch from obturator

14

Hip Flexors - Pectineus

Function

Adducts and flexes hip, and assists with medial rotation

15

Hip Flexors - Sartorius

Attachments

Anterior superior iliac spine to the superior part of the medial surface of the tibia

16

Hip Flexors - Sartorius

Innervation

Femoral nerve (L2,3)

17

Hip Flexors - Sartorius

Function

Flexes, abducts, and laterally rotates hip, and flexes knee

18

Knee extensors - Quadriceps

Rectus femoris attachments

AIIS, ilium above acetabulum

19

Knee extensors - Quadriceps

Vastus lateralis attachments

Greater trochanter and lateral linea aspera

20

Knee extensors - Quadriceps

Vastus medialis attachments

Intertrochanteric line and medial linea aspera

21

Knee extensors - Quadriceps

Vastus intermedius attachments

Anterior and lateral shaft of femur

22

Knee extensors - Quadriceps

All quadriceps distal attachments

Quadriceps tendon then tibial tuberosity via patellar ligament

23

Knee extensors - Quadriceps

Function

Extend knee (rectus femoris also flexes hip)

24

Knee extensors - Quadriceps

Innervation

Femoral nerve (L2,3,4)

25

Femoral Nerve

Route and branches

Deep to inguinal ligament, medial to ASIS, on tendon of iliopsoas m. 

Muscular branches - anterior thigh

Articular branches - hip and knee

Cutaneous branches - anteromedial thigh

Saphenous nerve is terminal cutaneous branch to anteromedial knee, leg and foot.
