Back Of Leg

Question 1

Superficial muscles of back of leg

Answer 1

Gatronemius: lateral and medial head. Condyle, knee joint.
Soleus: fibula, 1/4th, soleal line on tibia, tendinous soleal arch
Plantaris: lateral supracondylar line, oblique popliteal ligament.
Tibial nerve.
Plantar flexion. Speed

Question 2

Why is soleus called peripheral heart?

Answer 2

Large, valveless venous sinuses. Muscle contracts, venous return.

Question 3

Deep muscles of back of leg

Answer 3

Popliteus: lat surface of lat condyle of femur; tibia above soleal line.
Flexor digitorum longus: tibia upper 2/3rds
Flexor hallucis longus: fibula, lower 3/4th, interosseous mb
Tibialis posterior: upper 2/3 lat part of tibia, fibula, interosseous mb; tuberosity of navicular.

Question 4

Posterior tibial artery

Answer 4

Lower border of popliteus, postmed side of ankle.
Superficial n deep relations.
Branches: peroneal, muscular, nutrient artery to tibia.
Anastomotic: circumflex fibular, comm branch, malleolar, calcaneal.
Terminal

Question 5

Peroneal artery

Answer 5

Largest, 2.5 cm below lower border of popliteus. Fibula, inferior tibiofibular and ankle joints.
Muscular- post&lat comp
Nutrient artery to fibula
Anastomotic: comm branch to comm branch of post tibial
Large perforating branch
Lateral malleolar
Calcenean

Question 6

Tibial nerve

Answer 6

Similar to post tibial artery. 
Branches: muscular- tibialis post, flexor digi longus, flexor hallucis longus, deep part of soleus
Cutaneous: med calcanean
Articular
Terminal

Med tubercle of calcaneous 
Tendon of tibialis posterior
Tendon of flexor digitorum longus
Post tibial artery and terminal, venae
Tibial nerve and terminal 
Tendon of flexor hallucis longus. 
Tarsal tunnel. 
Origin to abductor hallucis.
