1

what aspect of the leg is the great saphenous vein

medial

2

is the popliteal vein superficial or deep

deep

3

where is the femoral nerve formed?
what nerves make up it

lumbar plexus
L2, L3, L4

4

what nerve branches from the femoral nerve to supply the anteromedial aspects of the knee, leg and medial foot

saphenous nerve

5

what forms the borders of the femoral triangle

what does it contain?

inguinal ligament
adductor longus
sartorius

NAVY
femoral nerve
femoral artery
femoral vein
deep inguinal lymph nodes

6

does the femoral sheath envelope the femoral nerve?

no
only the femoral artery and vein

7

what is the femoral artery a continuation of

external iliac > femoral artery

8

what nerve supplies the first web space of the foot?

deep fibular nerve

9

what does the sural nerve supply

skin of posteriolateral aspect of leg and lateral margin of foot

10

which branches of the femoral arteries supply most of the blood to the head of the femur

retinacular branches

11

the femoral artery goes through the ?? to become the ?? artery

adductor hiatus
popliteal

12

where does the iliopsoas insert
what merge to form it?
nerve supply?

lesser trochanter
psoas major and iliacus merge to form it
anterior rami of lumbar spinal nerves

13

insertion and attachment of sartorius

ASIS
superior part of proximal tibia

14

quadriceps femoris is composed of ...
common attachment

rectus femoris
vastus lateralis
vastus medialis
vests intermedius

all attach distally onto patella (indirectly onto tibial tuberosity via patellar tendon)

15

innervation of quadriceps femoris

femoral nerve

16

where does pectineus originate and attach

superior ramus of pubis
> pectineal line of femur

psoas minor
originate from?

psoas major - T12-L5
psoas minor - T12-L1

18

medial thigh - the ?? group

adductor

19

gracilis

20

nerve supply to adductors brevis and longus

obturator

21

nerve supply to gracilis

obturator

22

what is the hamstring part of the adductor magnus supplied by?

tibial nerve

the only exception to the medial compartment! all rest are obturator

23

femoral nerve

L2-L4

24

lymph from great saphenous vein goes to ....
lymph fro the small saphenous vein goes to ....

great saphenous > superficial inguinal > external iliac

small saphenous > popliteal > deep inguinal > external iliac

25

the external iliac artery becomes the femoral artery distal to the .. ?

inguinal ligament

26

medial and lateral circumflex arteries arise from the ...

profunda femoris artery

27

supplies most of the blood to the head and neck of the semis

medial circumflex artery

muscle binding the popliteal fossa
superiomedially?
superiolaterally?
inferiorly?

superiomedially = semimembranosus and semitendonosus
superiolaterally = biceps femoris
inferiorly = gastrocnemius

29

what does the common fibular nerve wind around before it divides?

the fibular neck
