A7 - gait/lower limb 1 Flashcards
what does the head of the femur articulate with?
acetabulum to form hip joint
what is the head of the femur covered in? exception?
articular cartilage except at fovea
what does the angle of projection of the neck of the femur allow?
an increased range of movement at the hip joint
what does the intertrochanteric line become after is passes the lesser trochanter on the posterior surface?
pectinate line
what does the intertrochantic crest have on its superior half?
a rounded tubercle called the quadrate tubercle — where quadratus femoris attaches
label the superior half of the femur
where does gluteus maximus attach?
gluteal tuberosity
the linea aspera splits to form what?
lateral and medial supracondylar lines
where does the medial supracondylar line end?
adductor tubercle
what attaches to the adductor tubercle?
adductor magnus
where does the flat popliteal surface lie?
between the 2 supracondylar lines
where do the medial and lateral collateral ligaments originate?
lateral and medial epicondyles
is the lateral or medial epicondyle larger?
medial
which condyle of the femur is larger and how does this help?
lateral condyle is more prominent — helps prevent the natural lateral movement of the patella
what do the posterior, inferior and anterior surfaces of the medial and lateral condyles articulate with?
- posterior and inferior with tibia and menisci of knee
- anterior with patella
what does the intercondylar fossa contain?
2 facets for attachment of intracorpuscular knee ligaments
what attaches to the medial aspect of the lateral condyle of the femur?
anterior cruciate ligament (ACL)
what attaches to the lateral aspect of the medial condyle?
posterior cruciate ligament (PCL)
the intercondylar eminence of the tibia projects upwards on either side to form what?
the intercondylar tubercels
the condyles of the tibia forms a flat surface known as what?
the tibial plateau
what does the tibial plateau articulate with?
femoral condyles to form the key articulation of the knee joint
what do the intercondylar tubercles of the tibia articulate with?
the intercondylar fossa of the femur
label the proximal part of the tibia
