Femoral nerve (L2,3)

Flex, abduct, laterally rotate hip; flex knee

sitting crossed legged

Question 11

Rectus femoris

Answer 11

AIIS, ilium above acetabulum
> Quadriceps tendon then tibial tuberosity via patellar lig

Extend knee , also flexes hip

Femoral nerve (L2, 3,4)

Gr. Trochanter & lateral linea Aspera

> Quadriceps tendon then tibial tuberosity via patellar lig

Extend knee

Femoral nerve (L2, 3,4)

Question 13

Vastus medialis

Answer 13

Intertrochanteric line and medial linea Aspera

> Quadriceps tendon then tibial tuberosity via patellar lig

Extend knee

Femoral nerve (L2, 3,4)

Question 14

Vastus intermedius

Answer 14

Ant.and Lat. shaft of femur

> Quadriceps tendon then tibial tuberosity via patellar lig

Extend knee

Femoral nerve (L2, 3,4)

Question 15

Where does the femoral nerve pass?

Answer 15

Deep to inguinal ligament, medial to ASIS, on tendon of iliopsaos m

Question 16

Answer 19

cutaneous branch - anteromedial knee, leg and foot

Question 20

Hip Adductors in the medial thigh

Answer 20

Gracilis 
Adductor Longus 
Adductor Brevis 
Adductor Magnus 
Obturator Externus

Question 21

Gracilis

Answer 21

Body and inferior ramus of pubis -> Superior Medial surface Tibia

Obturator (L2,3)

Adductts hip, flexes knee

Question 22

Adductor Longus

Answer 22

Body of pubis -> Middle 1/3 Linea aspera

Obturator (L2,3,4)

Adducts thigh

Question 23

Adductor Brevis

Answer 23

Body and Inferior ramus of pubis -> Pectineal line and proximal Linea Aspera

Obturator (L2,3,4)

Adducts thigh (may assist flexion)

Question 24

Adductor Magnus

Answer 24

Ischiopubic ramus and ischial tuberosity > Linea aspera, med. Supracindylar line, Adductor tubercle

Obturator (L2,3,4)
Hamstring part = tibial division of sciatic n. (L4)

Adducts thigh
Adductor part flexes and hamstring part extends thigh

Question 25

Obturator Externus

Answer 25

Margin of obturator foramen and obturator membrane -> Trochanteric fossa Obturator n. (L3,4) Laterally rotates thigh In adductor compartment BUT NOT AN ADDUCTOR

Question 26

Obturator nerve

Answer 26

Anterior divison L2-4 | Runs along lateral wall of pelvis to the obturator canal

Question 27

Adductor Canal

Answer 27

Apex of Femoral Triangle > Adductor Hiatus Underlies the distal half of sartorius muscle Boundaries: Sartorius Vastus medialis Adductor longus

Question 28

What two features enter adductor canal?

Answer 28

Femoral vessels: pass through adductor hiatus to reach popliteal fossa Saphenous nerve : passes between sartorius and gracilis to supply skin of anteromedial knee, leg and foot

Question 29

What is the femoral artery a continuation of?

Answer 29

The external iliac artery

Question 30

Route of the femoral artery

Answer 30

Femoral triangle > Adductor canal > Adductor hiatus to become popliteal a.
