What is the superior border of the popliteal fossa?
What is the superolateral border of the popliteal fossa?
What is the inferior border of the popliteal fossa?
medal and lateral heads of gastrocnemius
Where does the small saphenous vein drain into the popliteal vein?
passing through the deep fascia (popliteal fascia) in the median plane of the limb
Where is the neurovascular bundle foudn in the popliteal fossa?
median plane of the fossa
What are the contents of the neurovascular bundle in the popliteal fossa from superficial to deep?
tibial nerve; popliteal vein; popliteal artery
What is the popliteal vein a continuation of?
posterior tibial veins
Where are the popliteal lymph nodes located?
along the poplitea vein in the fossa
What is the route of the common fibular nerve in the popliteal fossa?
skirts the lateral border of the fossa, deep to biceps femoris tendon leaving the fossa between that tendon and the lateral head of gastrocnemius to reach the fibular neck
What does the common fibular nerve divide into?
deep and superficial fibular nerves
What nerves supply skin and fascia on the posterolateral aspect of hte leg and foot?
What are the sural cutaneous nerves derived from?
both the tibial and common fibular give off a branch: tibial-medial sural cutaneous nerve; common fibular- lateral sural cutaneous nerve
How do the medial sural cutaneous nerve and the lateral sural cutaneous nerve communicate with each other?
sural communicating branch
What forms the sural nerve?
medial sural cutaneous nerve plus the fibres in the communicating branch
What does the sural nerve follow in the posterior leg?
small saphenous vein
What muscles lie deep to the lateral head of gastrcneumius?
small plantaris muscles and popliteal muscle
What does the tibial nerve give branches to whilst in the popliteal fossa?
both heads of gastrocneumius and the plantaris muscles and the popliteus muscle
What nerve can be dammaged in fractures of the fibular neck?
common fibular nerve
What are the superfiical muscles of the posterior leg?
gastrocnemius; soleus; plantaris
What are the deep muscles of posterior leg?
flexor hallucis longus; flexor digitorum longus; tibialis posterior; popliteus
What are the general actions of hte posterior leg?
plantar flexion of the ankle and toes
What does the tibialis posterior assist tibialis anterior to do?
inversion of the foot
What nerve supplues the posterior leg?
How does the tibial nerve travel through the posterior leg compartment?
deep of soleus in the company of the posterior tibial arery (and accompanying veins)
What accompanies the tendons of the deep muscles of the posterior compartment to the sole of the foot?
posterior tibial aretry and the tibial nerve
What is the order from anterior to posterior of the deep muscle tendons and accompanying structures leaving the posterior compartment?
tendon of Tibialis posterior
tendon of Flexor digitorum longus
posterior tibial artery
tendon of flexor hallucis longus
What is the mnemonic for remembering the deep muscle tendons and atructures order in going to the sole of foot?
Tom, Dick ANd Harry
How do Tom, Dick ANd Harry reach the sole of the foot?
pass posterior to the medial malleolus and deep to the flexor retinaculum
What are the 2 heads and muscle bellies of gastrocnemius?
medial and lateral
