Flashcards in Anterior thigh Deck (26):
1

Muscles of the anterior thigh

Iliacus,
Psoas major and minor,
Pectineus,
Sartorius,
Quadriceps femoris

2

What muscles make up the iliopsoas

Psoas major and iliacus

3

Origin of psoas major

Lumbar vertebrae

4

Origin of iliacus

Iliac fossa of pelvis

5

Attachment of iliopsoas muscles

Lesser trochanter of femur

6

Action of iliopsoas

Hip flexion,
Assists in lateral rotation at hip

7

Innervation of iliacus

Femoral nerve (L2-L4)

8

Origin of pectineus

Pectineal line on anterior pelvis

9

Attachment of pectineus

Pectineal line on posterior femur, just inferior to lesser trochanter

10

Action of pectineus

Hip flexion,
Adduction at hip

11

Innervation of pectineus

Femoral nerve and branch of obturator nerve

12

Origin of sartorius

ASIS

13

Attachment of sartorius

Superior medial tibia

14

Action of sartorius

Abduction, flexion and lateral rotation at hip
Knee flexion

15

Innervation of sartorius

Femoral nerve (L2-L4)

16

Innervation of psoas major

Anterior rami of L1-L3

17

What are the muscles of quadriceps femoris

Vastus medialis, intermedius and lateralis
Rectus femoris

18

Attachment of quadriceps femoris

Patella ligament which attaches to tibial tuberosity

19

Origin of vastus medialis

Intertrochanteric line of femur (lateral side)

20

Origin of vastus intermedius

Anterior lateral femur

21

Origin of vastus lateralis

Greater trochanter

22

Origin of rectus femoris

ASIS, superior to acetabulum

23

Action of quadriceps femoris

Hip flexion (only rectus femoris crosses hip joint)
Knee extension

24

How do you test femoral nerve damage

Patient lies in supine position with knee flexed
Resist patients extension of leg
This tests quadriceps femoris muscles

25

Action of anterior thigh muscles

Hip flexion,
Knee extension

26

Innervation of quadriceps femoris

Femoral nerve
