what muscles does the lesser trochanter attach?
psoas major, iliacus
what muscles does the intertrochanteric crest attach?
quadratus femoris
what muscles does the intertrochanteric line attach?
vastus medialis, and vastus intermedius
what muscles attach to the gluteal tuberosity
gluteus maximus
what muscles attach to the linea aspera
vastus lateralis, vastus medialis, adductor muscles, biceps femoris
what forms the boundaries of the popliteal surface
supracondylar lines
what separates the medial and lateral condyles of the femur? what do they attach to?
separated by the intercondylar fossa, attach to the tibia
what attaches to the medial epicondyle of the femur?
medial collateral ligament, adductor magnus, gastrocnemius
what attaches to the lateral epicondyle of the femur
lateral collateral ligament, gastrocnemius
what part of the femur houses the patella?
patellar surface
What kind of bone is the patella? what houses it?
sesamoid bone, housed in the tendon of the quadriceps
how does the patella articulate with the femur
the medial and lateral articular surfaces
what is the main function of the patella
protects the knee joint, acts as a lever
what does the patella consist of?
apex, kneecap, base
what parts of the tibia articulate with the femur?
medial crural region, medial and lateral condyles
what separates the medial and lateral tibial condyles
intercondylar eminence
what part of the tibia articulates with the fibula? what does it form?
fibular articular facet, forms the tibiofibular joint
what attaches to the tibial tuberosity?
patellar ligament
what is the patellar ligament
distal portion of the quadriceps femoris tendon
what does the fibular notch of the tibia articulate with? fprm?
fibula, forms the inferior tibiofibular joint
what part of the tibia is also part of the ankle joint?
medial malleolus
what are the parts of the fibula
lateral crural region, head, shaft, lateral malleolus
what does the head of the fibula articulate with?
lateral condyle of the tibia
what part of the fibula is also part of the ankle joint?
lateral malleolus
what do the tarsals articulate with?
tibia, fibula, metatarsals
what part of the talus articulates with the tibia.
medial malleolar facet and trochlea
what part of the talus articulates with the fibula?
lateral malleolar facet
what does the calcaneus attach?
achilles tendon
what do the metatarsals articulate with?
tarsals and phalanges
what forms the ball of the foot?
head of the metatarsals
what are the arches of the foot?
medial longitudinal arch, lateral longitudinal arch, transverse arch
what supports the arches of the foot? function of the arches?
interlocking tarsal bones, strong ligaments, pull of tendons
function: shock absoprtion
what produce the medial longitudinal arch? high or low?
produced by the talus at the talonavicular joint
high arch
what produces the lateral longitudinal arch? high or low?
produced by cuboid
low arch
what produces the transverse arch?
follows the tarsometatarsal joints
where is the superficial fascia located? what does it contain?
deep to skin
contains loose connective tissue, adipose, superficial veins, lymphatic vessels and cutaneous nerves
where is deep fascia located? function?
envelops muscles, strong, improves muscle contraction, aids in venous blood flow return to heart
what are the divisions of the deep fascia?
fascia lata and crural fascia
what is the function of the saphenous opening? what division?
allows great saphenous vein to drain into the femoral vein, located in fascia lata
