Anatomy Dissection 4 Flashcards
What is the superomedial boundary of the popliteal fossa
Semitendinosus/ semimembranosus
What is the superolateral boundary of the popliteal fossa
Biceps femoris
What are the interior boundaries to the popliteal fossa
Medial and lateral heads of gastrocnemius
How does tibial nerve run in popliteal fossa
Vertically
What branch does tibial nerve give off
Medial sural nerve
How does common fibular nerve run in popliteal fossa
Skirts lateral border
What branch does common fibular nerve give off
Lateral sural nerve
What are the things in nervovascular bundle in popliteal fossa
Tibial nerve, popliteal vein and popliteal artery
What are important collaterals when the popliteal artery is partially occluded
Genicular anastomoses
What are the deep muscles of the posterior leg
Popliteus, flexor hallucis longus, flexor digitorium longus , tibilias posterior
What are the 3 superficial posterior leg muscles
Gastronecimus, soleus and plantaris
Where does gastronecimus attach proximally and distally
Proximally on the femoral condoyles, distally to calcaneus via achilles tendon
From anterior to posterior, what passes posterior to medial malleolus to reach sole of foot
Tibilias posterior, flexor digitorium longus , posterior tibial artery, tibial nerve, flexor hallucis longus
What does the soleus attach to proximally and distally
Proxomially to the soleal line on tibia and the fibula neck, distally to calcenus via achilles tendon
Where does the popliteal artery divide
Immediately distal to popliteal fossa
