Femoral Triangle Flashcards
(40 cards)
what are the nerves of the lumbar plexus
iliohypogastric, ilioinguinal, gentiofemoral, lateral cutaneous nerve of the thigh, lumbrosacral trunk, femoral an obturator
what exits the pelvis via the greater sciatic foramen
sciatic and gluteal nerves
where does the femoral nerve and vessels exit the pelvis
subinguinal space
where does the obturator nerve exit the pelvis from
the obturator canal
what is the femoral nerve composed of
anterior divisions of L2, L3 and L4
what does the femoral nerve innervate
the anterior thigh
what is the obturator nerve compose of
anterior divisions from L2, L3 and L4
what does the obturator nerve innervate
the medial thigh
what is the sciatic nerve composed of
divisions from the lumbrosacral trunk and sacral nerves S1, S2 and S3
what does the sciatic nerve innervate
the posterior thigh
what do the branches of the sciatic nerve innervate
leg and foot
what are the superficial structures of the femoral triangle
superficial veins, superficial lymph nodes, cutaneous nerves and deep fascia
describe the deep fascia
extremely tough connective tissue
what are the superficial veins
the great and short saphenous veins, accessory saphenous veins, superficial circumflex iliac and the superficial epigastric
where does the great saphenous vein begin
at the big toe
what are the two groups of superficial lymph nodes
horizontal and vertical
what does the horizontal group of superficial lymph nodes contain
medial nodes and lateral nodes
what area do the medial nodes drain
the anterior abdominal wall and the lower wall of the anal canal
where do the lateral nodes drain
the posterior abdominal wall
where do the vertical lymph nodes drain
the superficial lower limb
what are the two regions of deep fascia within the lower limb
fasciae latae and crural fascia
fasciae latae
covers the thigh and thickens laterally to form the iliotibial tact
where does the iliotibial tract run from/to
iliac tubercle to the anterolateral tibial tubercle
what is the function of the iliotibial tract
helps support the femur on the tibia while standing
