1

name the key areas in the lower limb

  • the femoral triangle
  • the femoral canal
  • the adductor canal
  • the popliteal fossa

2

draw the femoral triangle and label its borders

3

name borders of the femoral triangle

- lateral border: medial sartorius

- medial border: medial adductor longus

- superior: inguinal ligament

4

contents of the femoral triangle

NAVEL

5

NAVEL

femoral nerve

femoral artery

femoral vein

empty space (femoral canal)

lymphatics

6

what surroudns the femoral vein, artery and lympathics

femoral sheath

7

the femoral canal is located

in the medial anterior thigh within the femoral triangle

8

shape of the femoral canal

rectangular

9

borders of the femoral canal

  • medial border- lacunar ligament
  • lateral border- femoral vein
  • anterior border- inguinal ligament
  • posterior border- pectineal ligament, superior rmaus of the pubic bone and pectineus muscle

10

contents of the femoral canal

lympathic vessel

deep lymph nodes (lacunar node)

Empty space

Loose connective tissue

11

empty space in the femoral canal allows

distension of the adjacent fmeoral vein - can cope with increased venous return

12

adductor canal

15cm extending from the apex of the femoral triangle to the adductor hiatus of the adductor magnus

13

role of the adductor canal

passageway for sturctures moving from the anterior thigh to the posterior thigh

14

anteromedial border of the adductor canal

sartorius

15

lateral border of the adductor canal

vastus medialis

16

posterior border of the adductor canal

adductor longus and magnus

17

contents of the adductor cxanal

femoral arery 

femoral vein

nerve to vastus medialis

saphenois nerve 

18

after the adductor canal the femoral artey becomes the 

popliteal artery

19

after the adductor canal the femoral vein becomes

popliteal vein

20

the saphenous nerve is the

largest cutaneous branch od the femoral nerve

21

popliteal fossa

  • diamond shaped area
  • posteiror aspect of the knee
  • how nerves pass from the thigj to the leg

22

draw the popliteal fossa borders

23

 contents of the popliteal fossa

lateral to medial

  • common fibular nerve (innervates the short head of the biceps femoris)
  • tibial nerve
  • popliteal vein
  • popliteal artery

24

small muscle that forms part of the inferolateral wall

plantaris
