🗑
Vastus lateralis   upper part of intertrochanteric line, baseof greater trochanter and lateral lip of linea aspera   common tendon of insertion into patellar ligament int tibial tuberosity   femoral nerve   extension of leg at knee joint; strengthen knee via retinacula  
🗑
Vastus medialis   lower part of intertrocanteric line, medial to the pectineal line and along medial lip of linea aspera   common tendon of insertion into patellar ligament int tibial tuberosity   femoral nerve   extension of leg at knee joint; strengthen knee via retinacula; prevent lateral movement of patella  
🗑
Vastus intermedius   anterior and lateral sufaces of shaft of femur   common tendon of insertion into patellar ligament int tibial tuberosity   femoral nerve   extension of leg at knee joint  
🗑
