What is contained in the anterior compartment of the thigh?
Extensors of the knee, flexors of the hip, femoral nerve
What is contained in the medial compartment of the thigh?
Adductors of thigh, obturator nerve
What is contained in the posterior compartment of the thigh?
Flexors of the knee, extensors of the hip, sciatic nerve divisions
What are the muscles in the anterior compartment of the thigh
Iliopsoas, sartorius, rectus femoris, vastus lateralis, vastus medialis, vastus intermedius
What are the muscles in the medial compartment of the thigh
Pectineus, adductor longus, adductor brevis, adductor magnus 1, adductor magnus 2, gracilis, obturator externus,
AOII of iliopsoas
Action: Flexes thigh
Origin: iliac fossa & T12-L5 vertebral bodies
Insertion: Lesser trochanter
Innervation:Femoral nerve
AOII of sartorius
Action: Flexes, abducts, lateral rotation of thigh, flexes knee
Origin: Anterior superior iliac spine (ASIS)
Insertion: Medial surface of superior tibia
Innervation:Femoral n.
AOII of rectus femoris
Action:Extends knee, flexes thigh
Origin: Anterior inferior iliac spine (AIIS)
Insertion: Tibial tuberosity via patellar tendon & ligament
Innervation: Femoral n.
AOII of vastus lateralis
Action: extends knee
Origin: Greater trochanter & lateral lip of linea aspera
Insertion: Tibial tuberosity via patellar tendon & ligament
Innervation: Femoral n
What are the muscles of the quadriceps femoris muscle
Rectus femoris, vastus lateralis, vastus medialis, vastus intermedius,
AOII of vastus medialis
Action: Extends knee
Origin: Intertrochanteric line & medial lip of linea aspera
Insertion: Tibial tuberosity via patellar tendon & ligament
Innervation: Femoral n.
AOII of vastus intermedius
Action: extends knee
