Answer 1

Femoral artery (deep)
Femoral Nerve

Pectineus
Illopsoas 
-psoas
-iliacus
Sartorius 
Quadriceps femoris
- rectus femoris (+hip flexion)
- vastus lateralis
- vastus intermedius
- vastus medialis
^ all knee extension

Articularis Genu

Question 2

Medial thigh

Answer 2

Obturator artery
Obturator nerve (except adductor magnus hamstring portion --> sciatic nerve, tibial division)

• adductor longus
• adductor brevis
• adductor magnus
• gracilis
• obturator externus

Question 3

Posterior thigh

Answer 3

Deep femoral artery (perforating branches)
Sciatic nerve, tibial division

• semitendinosus
• semimembranosus
• biceps femoris (long and short head)
  ^ all knee flexion and hip extension (except short head is NOT hip extender)

HAMSTRINGS

Question 4

Gluteal compartment

Answer 4

Superior/inferior gluteal arteries,
Superior/inferior gluteal nerves, anterior sacral rami, nerve to obturator internus, nerve to quadratus femoris

• Gluteus maximius
• Gluteus medius
• Gluteus minimus
• piriformis
• superior gemellus
• obturator internus
• inferior gemellus
• quadratus femoris

Question 5

Anterior leg

Answer 5

Anterior tibial artery
Deep peroneal (fibular) nerve

• Tibialis anterior
• extensor digitorum longus
• extensor hallucis longus
• peroneus (fibularis) teritus
  ^ dorsiflexion of foot (all), digit extension (EHL, EDL), inversion (TA), eversion (FT)

Question 6

Lateral leg

Answer 6

peroneal (fibular) artery branches
Superficial peroneal (fibular) nerve

• peroneus (fibularis) longus
• peroneus (fibularis) brevis
  ^ evert foot, weak plantarflexion

Question 7

Superficial posterior leg

Answer 7

Posterior tibial artery, peroneal (fibular) artery branches
Tibial nerve

• gastrocnemius
• soleus
• plantaris
  ^ flex leg at knee (gastroc), plantarflexion (all)

Question 8

Deep posterior leg

Answer 8

Popliteal artery, Posterior tibial artery, peroneal (fibular) artery
Tibial nerve

• popliteus
• flexor hallcius longus
• flexor digitorum longus
• tibialis posterior
  Unlock knee (popliteus), foot plantarflexion (FHL/FDL/TP), digit flexion (FHL/FDL)
