anterior and medial thigh Flashcards
what are the two major superficial veins?
great and small saphenous vein
the union of the dorsal vein of the great toe and the dorsal venous arch give rise to?
the great saphenous vein
what does the great saphenous vein empty into?
femoral vein
where does the great saphenous vein run?
superiorly along medial aspect of the leg and thigh and traveling through an opening in fascia lata aptly called saphenous opening
what does the small saphenous vein arise from?
the lateral side of the foot where the dorsal vein of the small toe meets the dorsal venous arch
what does the small saphenous vein empty into?
the popliteal vein
what are perforating veins?
they pierce the deep fascia and always allow blood from superficial to deep only because of the presence of valves
what are risk factors for a DVT?
virchow’s triad (hypercoaguability, stasis, and endothelial injury)
what could a DVT lead to?
pulmonary embolism
where does fascia lata attach?
attaches superiorly to the inguinal ligament, pubic arch, body of pubis and pubic tubercle; laterally and posteriorly to the iliac crest and posteriorly to the sacrum, coccyx, sacrotuberous ligament, and ischial tuberosity
what is the iliotibial tract?
extremely strong, thickened lateral component of the fascia lata
what does the IT band enclose?
muscles and tensor fascia lata and the gluteus maximus
where does the IT band attach distally?
to the tubercle of the lateral condyle of the tibia (Gerdy’s tubercle)
what does the saphenous opening allow for and where is it?
inferior to the medial part of the inguinal ligament, permits the passage of the great saphenous vein
what is crural fascia?
deep fascia of the leg continuous with fascia lata
what is the femoral triangle?
a junction region between the trunk and lower limb
what is the superior boundary of the femoral triangle?
inguinal ligament
what is the medial boundary of the femoral triangle?
adductor longus m
what is the lateral boundary of the femoral triangle?
sartorius m
what is the roof of the femoral triangle?
fascia lata and subcutaneous tissue and skin
what is the floor of the femoral triangle?
iliopsoas and pectineus m
what are the contents of the femoral triangle?
femoral n (and its branches)
femoral sheath (and its contents)
femoral artery (and many of its branches)
femoral vein (and tributaries)
lymph nodes
what is the femoral sheath?
a funnel shaped fascial tube extending about 4cm inferiorly from the inguinal ligament
what is the femoral sheath a continuation of?
transversalis fascia of the abdominal wall and the fascia covering the iliposoas m
what does the femoral sheath allow for?
femoral vessels to glide easily beneath the inguinal ligament during movements of the hip
what are the 3 compartments of the femoral sheath?
the lateral, intermediate, and medial compartment
what occupies the lateral compartment of the femoral sheath?
femoral artery
what occupies the intermediate compartment of the femoral sheath?
femoral vein
