Lower Extremities (phase 0) Flashcards
Anterior thigh muscles
Iliopsoas Tensor fascia lata Sartorius Pectineus QuadRICEPS femoris (RF, VL,VM,VI)
Tensor fascia lata
Flexes and MEDIALLY rotates the thigh
Supplied by the superior gluteal nerve
Sartorius
Flexes and laterally rotates the thigh
Supplied by femoral nerve
Origin of rectus femoris
Anterior inferior iliac spine
ASIS: muscle attachments
Origin of sartorius and TFL
