Leg Flashcards
3 compartments of thigh, their muscles and movements
- Posterior - semitendinous, semimenbranous, biceps femoris - movement at hip and knee
- Anterior - Quad group and sartorious, illiopsoas (semi), pectineus (semi) movement at hip and knee
- Medial - Adducter magnus, longus, brevis, pectineous, gracilis - movement at hip only
True and (not) true knee joints
true - tibiofemoral
false - patellofemoral
2 depressions between condyles
intercondylar groove (ant and inf) and fossa (post)
tibial attachment for quad
tibial tuberosity
tibial plateaus for articular portions of femoral condyles
med and lat tibial plateaus
two knee menisci
lateral and medial
Number of patellar facets that are medial and lateral
medial - 1,2,3
lateral - 4,5,6,7
direction of patellar apex
inferior
femoral and patellar surface of PFJ joint
femoral - ant surface of femoral condyles and femoral sulcus
patellar - embedded in quad tendon
side patella most likely to slide out
medial due to steep lateral slope
4 ligaments of knee, attachments and movement restriction
- medial collateral lig (MCL) - med femoral condyle to medial tibia - limits opening medially - limits valgus
- Lat. collateral lig (LCL) - lateral femoral condyle to head of fibia - limits lateral openin (varus)
- Ant cruciate - ant tibia to lat, post femoral condyle - limits translation of tibia under femur
- Post cruciate - post intercondylar tibia to inner medial femoral condyle - prevent post translation of tibia
Attachment, action, nerve, and blood of semitendinous and semimembranous
Attach - isc tub to medial tibia
Action - hip ext and knee flex
Nerve - Sciatic
Blood - Femoral profundus
Attachment, action, nerve, and blood of biceps femoris
