Anatomy – Posterior Thigh and Popliteal Fossa

All muscles are innervated by tibial division of sciatic nerve EXCEPT
short head of biceps femoris which is supplied by common fibular division

Nerve supply to Bicep Femoris
Long head: tibial division of sciatic nerve
Short head: common fibular division of sciatic nerve

Action of Bicep Femoris
Flexion and lateral rotation of leg at knee joint
Extension of thigh at hip joint (long head only)

Flexion and medial rotation of leg at knee joint, Extension of thigh at hip joint
Semitendinosus, Semimembranosus actions

Blood supply to posterior thigh
Perforating branches of profunda femoris artery

Anatomical relationship of Sciatic Nerve, Long Head of Biceps Femoris and Adductor Magnus
Sciatic nerve is anterior to Adductor Magnus, deep to Long Head of Biceps Femoris

Boundaries of Popliteal Fossa
Superolateral: Biceps femoris
Superomedial: Semitendinosus and semimembranosus
Inferolateral: Lateral head of gastrocnemius and plantaris
Inferomedial: Medial head of gastrocnemius

Contents of Popliteal Fossa
Popliteal artery and vein, Terminal part of small saphenous vein, Tibial nerve, Common fibular nerve, Terminal part of posterior cutaneous nerve of thigh, Genicular branch of obturator nerve (terminal part of its posterior branch), Popliteal lymph nodes

How does the popliteal artery terminate
By dividing into the anterior and posterior tibial arteries

Muscular branches of popliteal artery
gastrocnemius, soleus, plantaris, and distal parts of hamstring muscles

Anatomical Relationships between Popliteal vein and artery; tibial nerve and popliteal vein
Popliteal vein lies posterior and slightly lateral to popliteal artery; Tibial nerve lies posterior and slightly lateral to popliteal vein

Popliteal Lymph Nodes
Receive superficial lymph vessels from lateral part of foot and leg; Receive deep lymph vessels accompanying anterior and posterior tibial vessels

Sural nerve: Formed by, Accompanies, Supplies
Formed by medial sural cutaneous nerve (branch of tibial nerve) and sural communicating branch; Accompanies small saphenous vein, Supplies skin over posterolateral aspect of leg and along lateral border of foot and little toe

Anatomical Relationship of Sural Nerve, Gastrocnemius, Calcaneal Tendon, Lateral Malleous
Sural Nerve will descend between 2 heads of gastrocnemius and posterior to calcaneal tendon; Will pass posterior and then inferior to lateral malleolus

Common injury site of commin fibular nerve
As it passes lateral to fibular neck, deep to fibularis longus muscle

Common fibular nerve passes superficial to what muscle
Lateral head of gastrocnemius

What is the branch of common fibular nerve within popliteal fossa? Describe it please:)
Lateral sural cutaneous nerve – Supplies skin of upper lateral part of leg, Gives off sural communicating branch that joins medial sural cutaneous nerve to form sural nerve
