Anterior and Medial Thigh Flashcards
Which muscle pills on the IT band to stabilize the knee and weakly rotate the hip?
the tensor fascia latae
the anterior compartment of the thigh is the ___ compartment.
the extensor compartment
Where does the great saphenous vein start? WHere does it terminate?
THrough what space does it travel to reach its termination point?
starts: medial end of the dorsal venous arch of the foot
end: femoral vein
passes through an opening in the fascia lata called the saphenous opening
What veins connect the superficial saphenous veing to the deep veins?
the perforating veins
What happens to the superficial veins if the valves stop working?
The blood vlow will reverse direction towards the superficial veins, causing them to become tortuous and dilated
= varicose veins
What is a saphenous cut down? WHere is it done?
When they use the saphenous vein for emergency transfusions when other IV access is unavailable.
it’s done 1 cm in fronf of the medial malleolus - the great saphenous vein is always there.
What muscle allows us to sit cross legged?
In other words, it flexes/laterally rotates hip and flexes/medially fotates knee
the sartorius muscle
What nerve innervates the sartorius muscle?
the femoral nerve
Where does the ilipsoas run from? WHat does it do?
from the transverse processes of the lumbar vertebrae to down to the lesser trochanter of the femur
It flexes the hip joint
How is the iliopsoas muscle innervated?
by the femoral nerve and the anterior rami of the lumbar plexus
What does the pectineus do?
It adducts and flexes the thigh at the hip joint. (stretches from the pubis down and over to inferior of the lesser trochanter
How is the pectineus innervated?
femoral nerve
What are the 4 muscles of the quadriceps femoris?
rectus femoris
vastus lateralis
vastus intermedius
vastus medialis
What do the quadricepts attach to distally?
to the patella and tibial tuberosity through the quadriceps tendon.
What do the quadricepts do?
they extend the leg
How are the quadriceps innervated?
femoral nerve
What ligament runs from the patella to the tibial tuberosity?
the patellar ligament
What branches of the lumbar plexus make up the femoral nerve?
L2, L3, and L4
WHat are the boundaries of the femoral triangle?
the inguinal ligament superiorly
the adductor longus medially
and the sartorius laterally
WHat are the contents of the femoral triangle?
NAVEL (laterally to medially)
femoral Nerve, femoral Artery, femoral Vein, (empty), inguinal Lymph nodes
What is the largest nerve coming off the lumbar plexus?
the femoral nerve
What artery provides the main arterial supply to the lower limb?
the femoral artery
THe femoral artery is a continuation of the ____ and becomes the _____ after it passes through the adductor hiatus.
continuation of the external iliac artery and beomes the popliteal artery
The femoral artery branches off into the deep femoral artery, which gives rise to the ____ and the _____, as well as the 4 _____ to the posterior compartment of the thigh.
lateral circumflex femoral
medial circumflex femoral
perforating branches
