Lecture 14: Anterior and Medial Thigh Flashcards
fascia lata
dense layer of connective tissue overlying muscles
great saphenous vein
originates from the medial aspect of the dorsal venous arch of foot and empties into femoral vein
iliotibial tract
longitudinal fibrous reinforcement of lateral aspect of fasica lata; provides attachment for gluteus maximus and tensor fascia lata
intermuscular septa
septa passes from the fascia lata to attach to the femur to create anterior and posterior compartments of the thigh
femoral triangle
sartorius (lateral)
adductor longus (medial)
inguinal ligament (superior)
pectineus, iliopsoas and adductor longus (floor)
fascia lata (roof)
femoral sheath
fascial tube containing the artery and vein, NOT the nerve
femoral canal
medial space within femoral sheath that allows for the femoral vein to expand
adductors canal
fascial tunnel covered by middle third of sartorius m. that conveys femoral vessels from femoral triangle to adductor hiatus

feature of the superior medial leg, is a conjoined tendons of three muscles that insert onto the anteromedial surface of the proximal tibia. (sartorius, gracilis and semintendinosus)
