Flashcards in Organization of the Lower Limb Deck (72)
lower limb joint?
-less mobility, more stability
capsule of hip joint?
limits extension and abduction
does little to inhibit flexion
what allows for actions of climbing and running?
modified hinge at knee and flexion at hip
little to add stability and strength
-mainly for muscle attachments
hinge joint to jump and run coupled with muscles strong enough to elevate the entire body mass
multiple joints in feet allow?
spring needed for cushioned landing and for negotiating uneven surfaces
superficial fascia of lower limb
two layers of superficial fascia ?
fatty and membranous layer
whats between fatty and membranous layer?
inguinal lymph nodes
subQ blood vessels and nerves
deep fascia of lower limb?
stocking like investment
attachments of deep fascia?
above to most of the inferior aspect of bony pelvis and attached to bony prominences at knee and ankle
continuity of deep fascia
-most superior portion of deep fascia
-surrounds thigh and portion of gluteal region
thickened portion of fascial lata
-extends inferiorly from posterior portion of iliac crest and forms an incomplete intermuscular septa between gluteus maximus and medius
what muscles is gluteal aponeurosis between?
lateral and medial when part of fascia lata
inward projections of fascia lata which extend to femur and delineate muscular compartments
lateral thickening of fascia lata
-serves as tendon for tensor facia lata and gluteus maximus
attaches inferiorly to tibia, head of fibula and blends with capsule of knee joint
saphenous vein opening
circular opening in superior anteromedial portion of the fascia lata below the inguinal ligament
-transmits the great saphenous vein
sickle shaped and part of saphenous vein opening
underlain with fascia cribrosa
extension of fascia lata below knee
anterior and posterior (when part of crural fascia)
-attach as inward extensions of crural fascia to fibula
-delineate anterior and lateral crural compartments
-attaches between tibia and fibula posteriorly
-delineate superior and deep posterior compartments
thickening of crural fascia at ankle which prevents tendons from bowstringing
-superior and inferior extensor retinacula (anterior)
-superior and inferior fibular retinacula (lateral)
-flexor retinacula - posteromedial
fascia of dorsum of foot?
continous with extensor retinacula
continuation of fascia of dorsum of foot onto the sole
thickened central portion - plantar aponeurosis
thickened central portion of plantar fascia
anterior femoral compartment
quads and sartorious
-flex thigh and/or extend leg
artery and nerve in anterior femoral compartment?
femoral artery and nerve
transitional space between abdominopelvic region and the lower limb
bounded by inguinal ligament, sartorious, adductor longus muscles, and covered by fascia lata
contents of femoral triangle?
femoral vein, artery, nerve, and deep inguinal lymph nodes
medial femoral compartment?
muscles within this compartment flex, adduct, and rotate the thigh
branches of obturator artery and nerve distribute within this compartment
