MSK lower limb Flashcards
what is the function of the iliofemoral ligament
prevents hyperextension of the hip joint
what is the function of the pubofemoral ligament
prevents over abduction
what two ligaments help form the sciatic foramens
sacrotuberus ligament and sacrospinous
action of the tensor fascia lata
flexes the thigh
medial rotation and abduction
role of the gluteus maximus
extends the thigh, lateral rotation
apart from the gluteus maximum what is the role of the muscles in the gluteal regions
abduct and medial rotation
what forms the iliotibial tract
combination of the gluteus Maximus and tensor fascia lata tendons
role of the pectineus
adduction and flexion
what is the main role of all the muscles in the medial thigh
hip adduction
what are the 3 ligaments of the hip
iliofemoral
pubofemoral,
ischiofemoral
what is the patellar ligament a continuation of
rectus femoris tendon
what do the collateral ligaments do
prevent excessive medial or lateral movement
what does the anterior cruciate ligament do?
prevents anterior dislocation of the tibia on the femur
what does the posterior cruciate ligament do
prevents posterior dislocation of the tibia on the femur
which cruciate ligament is weaker
anterior
what do the knee menisci do
shock absorber
deepen the joint cavity
help with lubrication and distribute axial load
what are the borders of the popliteal fossa
biceps femoris laterally
semimembranosus and semitendinsosus medially
where is a good surface marker for locating the femoral artery
in between the anterior superior iliac spine and the pubic tubercle
boundaries of the femoral triangle
medial boundary- adductor Longus
lateral boundary- sartorial
base- inguinal ligament
floor- pectineus and illiopsoas
what forms the medial malleolus
tibia
what forms the lateral malleolus
fibular
what muscles are in the anterior compartment of the leg
tibialis anterior
extensor digitorum longus
extensor hallucis longus
fibulas tertius
what is the action of the tibialis anterior
inversion and dorsiflexion
what nerve inervates the lateral compartment of the leg
superficial fibular nerve
