popliteal fossa, vessels and nerves of leg and dorsum of foot Flashcards
What are the boundaries of the popliteal fossa
superolateral: tendon of biceps femoris
superomedial: semimembranosus and semitendinosus
inferolateral: lateral head of gastroc
inferomedial: medial head of gastric
roof: popliteal fascia of fascia kata
floor: posterior surface of capsule of knee and popliteus m
contents of popliteal fossa
termination of post femoral cutaneous, division of sciatic, muscular and cutaneous of tibial, cutaneous of fibular, popliteal vein and tributaries, popliteal a, popliteal lymph nodes and vessels
what does the popliteal a turn into
anterior and posterior tibial a
What are the branches of popliteal a before it splits
lateral and medial superior genicular, lateral and medial inferior medial genicular, middle genicular, sural branches (2)
where are the lateral/medial superior & inferior genicular aa found
superior- superficial to heads of gastroc
inferior- deep to heads of gastroc
where does the middle genicular a arise from on popliteal a
anterior surface
where do the sural branches of popliteal a go
into lateral and medial heads of gastroc
what branches come off anterior tibial a when it first divides from popliteal
posterior tibial recurrent and circumflex fibular a
what are the branches of anterior tibial a when it is anterior and deep to tibialis anterior m
anterior tibial recurrent, medial and lateral malleolar branches, dorsalis pedis
what is the terminal branch of the anterior tibial a
dorsalis pedis a
what are the branches of dorsalis pedis a
lateral and medial tarsal aa
arcuate a
first dorsal metatarsal
deep plantar a
where does posterior tibial a course
deep to soleus and behind medial malleolus
what are the branches of posterior tibial a
circumflex fibular a (variable) fibular a communicating branch to fibular a posteiror medial malleolar medial calcaneal medial and lateral plantar
what does the fibular a supply
major blood supply to the lateral crural compartment
what are the branches of fibular a
muscular, nutrient a, communicating branch(with post tibial), perforating a, posterior lateral malleolar
