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
what cord levels are in the common fibular n
L4 L5 S1 S2
where does the common fibular n course in popliteal fossa
superficially and laterally within popliteal fossa
what cutaneous n does common fibular n give
lateral sural cutaneous n
where does the common fibular n travel after popliteal fossa
follow biceps femoris tendon to head of fibula
what m does common fibular n pierce
fibularis longus m inferior to the head of the fibula
what does the common fibular n divide into
superficial and deep fibular nn
what cord levels are in the superficial fibular n
L5 S1 S2
what mm does the superficial fibular n inn
fibularis longus and brevis
what does the superficial fibular n terminate as
medial and intermediate dorsal cutaneous nn to the dorsal digital for all toes
what cord levels are in the deep fibular n
L4 L5
what m does the deep fibular n pierce
extensor digitorum
what mm does the deep fibular n inn
all mm of the anterior compartment
what are the terminal branches of deep fibular n
lateral and medial
what does the medial branch of deep fibular n inn
web between first and second toes
What cord levels are in the tibial n
L4 L5 S1 S2 S3
while in the popliteal fossa what branches does the tibial n give off
branches to plantaris and gastroc, as well as medial sural cutaneous n
what forms the sural n
the communcating branch of the lateral and medial sural cutaneous nn
what does the sural n turn into
lateral dorsal cutaneous n to lateral surface of foot and fifth digit and lateral calcaneal branch
where does tibial n leave popliteal fossa
deep to gastrocnemius
what mm just out of the popliteal fossa does tibial n inn
soleus and popliteus
what a does the tibial n run with
the posterior tibial a and vv
what does the tibial n inn
all posterior leg mm
where does the tibial n exit leg
passes behing medial malleolus “TDANH”
what provides inn to medial surface of foot and medial posterior heel
saphenous n (most distal part of femoral n)
