Anatomy of the leg (calf)

Question 1

what fascia surrounds all the muscles of the leg?

Answer 1

investing deep fascia , attached to the tibia

Question 2

what are the fibrous fascia’s

Answer 2

• transverse intermuscular septum
• posterior crural intermuscualr septum
• Anterior crural intermuscular septum

Question 3

muscles for dorsiflexion (just lift the foot)

Answer 3

one muscle at the front -Tibialis anterior

it also has a role in inversion of the foot

Question 4

Muscles for planter flexion (lift the whole body)

GSP

Answer 4

• gastrocnemius ( 2 heads , medial and lateral condyles of femur)
• Soleus
  -plantaris
  both of their tendons unite to form the calcaneal tendon = heel chord or Acillies tendon

Question 5

extensor muscles pf the toe
2 long
2 short

Answer 5

• extensor hallucis longus (anterior compartment = extends big toe )
  -extensor digitorum longus (anterior compartment = extends the mcp of toes)
  BOTH ABOVE= POWERFUL dorsiflexors of the ankle
• extensor hallucis brevis + extensor digitorium brevi ( do the same as above but don’t dorsilflex the ankle )

Question 6

which muscles produce inversion of the foot ?

Answer 6

tibialis posterior

tibialis anterior

Question 7

which muscles produce eversion of the foot ?
x3
peroneus loves BT

Answer 7

peroneus longus
peroneus brevis
peroneus tertius

Question 8

veins of the leg

Answer 8

short saphenous vein ( back)
long saphenous vein (front )

deep => popliteal vein

Question 9

arteries of the leg

Answer 9

• popliteal artery :
• anterior tibial artery (forwards)
• ends by dividing into => posterior tibial artery + Peroneal artery

Question 10

nerve supply of the leg

Answer 10

• medial compartment => femoral , saphenous nerve

- anterior compartment =>common perineal nerve

Question 10

nerve supply of the leg

Answer 10

• medial compartment => femoral , saphenous nerve

- anterior compartment =>common fibular nerve
