Extension of the knee joint
Quadriceps tendon

Question 4

Rectus femoris ( nerve supply - action - origin - insertion?

-Pull the synovial membrane to prevent it from being trapped between patella and femur during extension

-synovial membrane of the knee joint

Question 6

Sartorius (nerve supply - action - origin - insertion )

Answer 6

Femoral nerve
- flexion of the hip
- flexion of the knee
- medial rotation of the leg
- ASIS
- Upper medial part of the tibia

Question 7

Pectineus ( nerve - action - origin - insertion )

Answer 7

-Femoral nerve

-Adduction , flexion , lateral rotation of the hip joint (thigh)

Question 8

Iliacus ( supply - action - origin - insertion )

Answer 8

-Femoral nerve
-Iliopsoas main flexor of the thigh
-Iliac fossa
-Lesser trochanter

Question 9

Psoas ( supply - action - origin - insertion )

Answer 9

-Lumbar plexus
-Iliopsoas is the main flexor of the thigh
- lumbar vertebral
- lesser trochanter

Question 10

Femoral triangle ( position- boundaries - roof - floor - contents )

Answer 10

Upper third of the front of the thigh

Base: inguinal ligament
Laterally: medial border of sartorius
Medially: medial border of adductor longus
Apex: meeting of the medial and lateral borders
Roof: skin, superficial fascia , deep fascia
Floor: adductor longus , pectineus , iliopsoas
Contents: femoral sheath , VAN , lymph nodes , sympathetic plexus around the femoral artery

Question 11

Femoral sheath (walls , compartments 3)

Answer 11

Walls:
- anterior : extension of the fascia transversalis of anterior abdominal wall.
- posterior: extension of the fascia iliaca of the posterior abdominal wall.

Compartments :
1- lateral : femoral artery and femoral branch of the genitofemoral nerve.
2- middle : femoral vein
3- medial : (femoral canal ) lymph nodes and fat.

Question 12

Medial compartments

Answer 12

1-muscles ( adductor longus, brevis, magnus and gracilis )
2- artery : obturator artery
3- nerve : obturator nerve
4- action: adduction, flexion and lateral rotation

Question 13

Adductor longus ( origin , insertion , nerve supply , action )

Answer 13

1- body of the pubis
2- middle third of the linea aspera
3- anterior division of the obturator nerve
4- adduction, flexion and lateral rotation of the thigh.

Question 14

Answer 14

1- pubic arch
2- lower half of the linea aspera
3- anterior division of the obturator nerve
4- adduction, flexion and lateral rotation of the thigh

Question 15

Gracilis ( origin , insertion , nerve supply , action )

Answer 15

1- pubic arch
2- medial surface of the tibia
3- anterior division of obturator nerve
4- adduction of the hip , flexion of the knee , medial rotation

Question 16

Adductor magnus ( origin , insertion , nerve supply , action )

Answer 16

Pubic part
1- outer surface of the pubic arch
2- gluteal tuberosity , linea aspera
3- posterior division of the obturator nerve
4- adduction , flexion and lateral rotation

Ischial part
1- ischial tuberosity
2- tendon into adductor tubercle
3- sciatic nerve
4- extension of the hip joint ( hamstring )
