1

Iliopsoas Inervation

FERMORAL NERVE (ILIACUS) & DIRECT BRANCHES FROM THE LUMBAR PLEXUS (L1-L3

2

Iliopsoas origin and insertion

ORIGIN
PSOAS MAJOR: VERTEBAL BODIES AND COSTAL PROCESSES OF L1-L5

ILIACUS: ILIAC FOSSA

Insertion
LESSER TROCHANTER OF THE FEMUS

3

Iliospoas action

Flexion of thigh at hip joint
External rotation of thigh
ALSO:
- trunk flexion and lateral bending

4

Gluteus Maximus innervation

inferior gluteal nerve

5

Gluteal maximus Origin and insertion

Origin: lateral sacrum, posterior gluteal surface and thoracolumbar fascia

Insertion
- ITT and gluteal tuberosity (on femur)

6

MOA Gluteal maximus

hip extensor and external rotation of the hip

Note:
Upper fibers: ABDUCt
Lower fibres: ADDUCT

7

Gluteus medius innervation

superior gluteal nerve

8

Gluteus medius MOA

Abduction
Internal rotation

Anterior part - flexion
Posterior part - Extension and External rotation

9

Gluteus medius Origin and insertion

Origin - gluteal surface of the ilium
Insertion
lateral surface of great trochanter

10

gluteus minimus O and I

Origin: gluteal surface of ilium
Inserts: anterolateral surface of greater trochanter

11

gluteus minimus innervation

superior gluteal nerve

12

MOA gluteus minimus

ABDUCTIOn and internally rotation

anterior part - flexion
posterior [art- extension and external rotation

13

TENSOR FACIA LATA innervation

Superior gluteal nerve

14

TFL origin and insertion

Origin - ASIS
Inserts - iliotibial tract

15

Action of TFL

Hip ABDUCTION
Hip Flexion
Hip internal rotation

FIA

16

Quadriceps femoris origin

Rectus femoris: AIIS

Vests lateralis : LATERAL GREATER TROCHANTER, LATERAL TO LINEA ASPERA

Vests intermedialis: ANTERIOR 2/3RDS SHAFT OF FEMUR

Vestus medalis: DISTAL INTERTROCHANTERIC LINE, MEDIAL TO LINEA ASPERA

17

Quadriceps origin

patella and tibial tuberosity

18

Quadriceps innervation

femoral nerve

19

Quadriceps action

HIP flexion
Knee extension

20

Sartorius O and I

Origin: ASIS
Innervation: medial to tibial tuberosity ( with the gracilis and semitendinosus - res anserinus )

21

Sartorius innervation

femoral nerve ( l2,3,4)

22

Sartorius action

Hip flexion, ABduction, ER
(FABER)

Knee flexion and internal rotation
(FIR)

23

Gracillus innervation

Obturator nerve L2-4

24

Gracillus Origin and insertion

origin: Inferior pubic ramus
Insertion
Medial : tibial tuberosity - with the satoris and semitendinosus 0 res anserinus "goose foot"

25

action of gracillus

adduction and hip flexion

knee flexion and internal rotation

26

Pectineus O and I

O: pecten pubis
I: pectineal line and proximal lines aspera

27

Pectineus innervation

Femoral

28

Pecineus action

hip adduction and external rotation (minor flexor)

29

Adductor longus inervation

obturator nerve L2-4

30

Adductor longus O and I

origin: superior pubic ramus
Insertion: linear aspect 1/3 of femur
