anatomical spaces Flashcards
borders: obturator foramen
floor: obturator externus
roof: obturator internus
contents: obturator foramen
smaller arteries and nerves leaving pelvis
example: obturator nerve
borders: greater sciatic foramen
sacrospinous ligament
contents: greater sciatic foramen
structures entering or leaving pelvis
(example: sciatic nerve)
what divides the greater sciatic foramen into a superior and inferior portion? and what contents do they contain?
piriformis
superior portion: superior gluteal nerve
inferior portion: inferior gluteal nerve
borders: lesser sciatic foramen
sacrotuberous ligament
contents: lesser sciatic foramen
structures entering or leaving perineum
(example: pudendal nerve)
borders: femoral triangle
superior: inguinal ligament
lateral: sartorius
medial: adductor longus
floor: pectineus, iliopsoas
contents: femoral triangle
VAN
medial –> lateral
vein (femoral): medial
artery (femoral)
nerve (femoral) = lateral
contents: adductor canal
femoral artery + vein
saphenous nerve
what is the adductor hiatus
opening between attachments of adductor magnus, allowing for contents of adductor canal to travel posteriorly through popliteal fossa
saphenous nerve does not go through
borders: popliteal fossa
*DIAMOND SHAPE
superomedial: semitendinosus
superolateral: biceps femoris (long head)
inferomedial: gastrocnemius (medial head)
inferolateral: gastrocnemius (lateral head)
contents: popliteal fossa
AVN
Artery (popliteal) = medial
Vein (popliteal)
Nerve (tibial) = lateral
tarsal tunnel: contents
Tom, Dick, and very nervous Harry
posterior tibilias = superior
flexor digitorum longus
tibial artery
tibial vein
tibial nerve
flexor hallucis longus = inferior
