Lower Limb and Foot Flashcards
(45 cards)
what does the femur articulate with?
pelvis (via head)
tibia (via condyles)
patella (via patellar surface)
what are the non-metric traits of the femur?
third trochanter (additional lateral tubercle at same level of the lesser trochanter) shape of the fovea capitis femoral bowing Allen's fossa (fossa on anatomical neck) Poirier's facet (extension of the head) anterior femoral neck torsion
what is the fovea capitis?
divit in the head of the femur
where is the intertrochanteric line?
between the greater and lesser trochanter on the anterior side of the femur
where is the intertrochanteric crest?
between the greater and lesser trochanter on the posterior side of the femur
where is the trochanteric fossa?
on the medial side of the greater trochanter
where is the pectineal line, what does it attach and what does it lead into?
inferior to the lesser trochanter
attaches pectineus
becomes the spiral line then the linea aspera
where is the gluteal tuberosity and what does it lead into?
inferior to the greater trochanter
becomes the linea aspera
what do the medial and lateral supracondylar lines form as a division of?
linea aspera
where is the quadrate tubercle located and what does it give attachment to?
on the intertrochanteric crest
insertion of quadratus femoris
where is the popliteal surface?
flat triangular surface between the medial and lateral supracondylar lines
where is the adductor tubercle?
on the medial epicondyle
what are the lateral and medial epicondyles?
lateral protrusions at the distal end of the femur, on the anterior surface
what are the lateral and medial condyles?
posterior protrusions at the distal end of the femur, on the posterior surface
what is the intercondylar fossa?
the fossa between the medial and lateral condyles
where is the patellar/trochlear surface?
anterior surface of the distal femur
site of articulation with the pelvis
where is vastus medialis and what is its function?
intertrochanteric line, medial lip of linea aspera and medial supracondylar line -> quadriceps tendon -> tibial tuberoisty (via patellar ligament)
extension of leg
where is vastus intermedius and what is its function?
anterior 2/3rds femur, linea aspera and lateral supracondylar line -> quadriceps tendon
extension of leg
where is vastus lateralis and what is its function?
intertrochanteric line, inferior greater trochanter, gluteal tuberosity and lateral lip of linea aspera -> quadriceps tendon
extension of leg
where is popliteus and what is its function?
lateral epicondyle of femur -> soleal line of tibia
medial rotation and flexion of leg
where is gastrocnemius and what is its function?
superior to articular surfaces of condyles -> posterior calcaneous via tendocalcaneous
flexion of knee and foot
where are the quadriceps muscles?
rectus femoris, vastus medialis and vastus intermedius and vastus lateralis
where is soleus and what is its function?
soleal line of tibia and upper posterior fibula -> posterior calcaneus
plantarflexion of foot
where is tibialis anterior and what is its function?
lateral condyle and upper half of lateral shaft of the tibia -> cuneiform and first metatarsal
dorsiflexion and supination of the foot
