The posterior leg Flashcards
Name the deep muscles of the posterior leg
- Tibialis posterior
- Flexor digitorum longus
- Flexor hallucis longus
- Popliteus
What tendons make the Achilles tendon?
- Gastronemius
- Plantaris
- Soleus
What runs through the tarsal tunnel?
- Tibialis posterior (Tom)
- Flexor digitorum longus (Dick)
- Posterior tibial artery (And)
- Posterior tibial vein (Very)
- Flexor hallucis longus (Harry)
What are the superficial veins of the posterior leg and where do they lie?
- Small saphenous lies laterally
- Great saphenous lies medially
Where does the great saphenous drain into?
-Femoral vein through Saphenous ring of femoral triangle
Where does the small saphenous vein drain into?
-Popliteal vein within the popliteal fossa
What is the sural nerve?
- Medial sural nerve and superficial fibular nerve anastamose to make sural nerve
- Cutaneous supply of posterior leg
What nerve supplies posterior leg?
-Tibial
What is the arterial supply to the posterior leg?
- Posterior tibial artery
- Fibular artery
- Popliteal artery
Where does the achilles tendon attach?
-Calcaneous
What are the two heads of gastronemius?
-Medial and lateral
What divides the superficial and deep compartments?
-Fascia
What is the function of the posterior compatment?
-Plantarflexion
What is the function of gastronemius?
- Plantarflexion of foot
- Flexion of knee
What is the function of plantaris?
- Plantarflexion of the foot
- Flexion of the knee
What is the function of soleus?
-Plantarflexion
What is the function of popliteus?
-Assists unlocking of the knee
Where does flexor hallucis longus insert?
-Plantar surface of great toe
What is the function of tibialis posterior?
- Plantar flexion
- Helps support arch of foot
- Inversion of the foor
What is the function of Flexor digitorum longus?
- Plantarflexion of the foot
- Inversion
- Plantarflexion of toes 2-5
What is the function of flexor hallucis longus?
- Plantar flexion of foot
- Inversion
- Plantarflexion of great toe
What are the functions of the posterior leg?
- Plantarflexion
- Involved in gait
- Propulsion to walk forward
- Flexion of the knee
- Inversion
Describe the route of the small saphenous vein
-Begins lateral and passes posterior to dive into popliteal fossa
What runs with the short saphenous vein?
-Sural nerve
Why are there may anastamoses from the superficial veins of the leg to the deep?
-The perforating veins allow blood to flow from superficial veins to deep veins to prevent DVT
Name the superficial muscles of the posterior leg
- Gastronemius
- Soleus
- Plantaris
