Flashcards in Anterior Thigh Deck (33):
1

What are the hip flexors of the anterior thigh?

Iliacus
Psoas major
Psoas minor
Pectineus
Sartorius

2

How many knee extensors are there in the anterior thigh?

4

3

What do we collectively call the knee extensors and what muscles make up this?

Quadriceps femoris:

Rectus femoris
Vastus medialis
Vastus intermedius
Vastus lateralis

4

Where does the iliacus originate?

Iliac fossa

5

Where do the iliacus and psoas major blend?

Iliac fossa

6

Where does the pectineus originate?

Pubis

7

Where does the pectineus attach?

Pectineal line on posterior femur

8

What nerve innervates the hip flexors? (Except psoas muscles)

Femoral nerve

9

How many hip flexors are in the anterior thigh?

5

10

Where does the sartorius originate?

Anterior superior iliac spine

11

Where does the sartorius attach?

Tibia (Pes Anserinus)

12

What are the branches of the femoral artery?

Deep artery of the thigh
Lateral circumflex
Medial circumflex

13

What forms the superior border of the femoral triangle?

Inguinal ligament (ASIS to pubic tubercle)

14

From lateral to medial, what structures occur in the femoral triangle?

Femoral nerve
Femoral artery
Femoral vein
Lymph nodes

15

What is the lateral border of the femoral triangle?

Medial border of sartorius

16

What is the medial border of the femoral triangle?

Medial border of adductor longus

17

What structures are included in the femoral sheath?

Femoral artery
Femoral vein
Lymph nodes

18

What structures are inside the femoral canal?

Lymphatic system/lymph nodes

19

What are the areas of the superior, anterior thigh called from largest to smallest?

Femoral triangle -> femoral sheath -> femoral canal

20

What is the femoral ring?

The opening of the femoral canal

21

Which 2 structures form the borders of the femoral canal?

Lacuna ligament
Pectineal ligament

22

Where can we feel the femoral pulse?

Half way between the ASIS and the pubic symphysis

23

Describe a femoral hernia

Bowel herniates through into the femoral canal
May get compressed against the lacuna ligament and form a strangulated hernia

24

What is a fascia iliaca block?

Injection of anaesthetic into space to bathe the femoral nerve and the lateral cutaneous nerve of the thigh
Helps with pain control after a fracture to the femur neck

25

Where is the iliopsoas bursa?

Deep to the iliopsoas

26

Where does the iliopsoas insert?

Lesser trochanter of femur

27

What is the action of iliopsoas?

Flexes hip
Lateral rotation at hip

28

What is the nerve supply to iliopsoas?

Psoas major = L1-L3 anterior rami
Iliacus = femoral nerve

29

What is the origin of rectus femoris?

Ilium

30

What is the insertion of rectus femoris?

Patella

31

What is the action of rectus femoris?

Flexes hip
Extends knee

32

What is the innervation of rectus femoris?

Femoral nerve

33

What are the borders of the femoral canal?

Anterior = inguinal ligament
Medial = lacuna ligament
Posterior = pectineal ligament
Lateral = femoral vein
