what nerve innervates the anterior compartment of thigh
Femoral nerve (L2-L4)
List the muscles of the anterior compartment
-function (excluding quadriceps femurs -later detailed)
-insertion
-attcthent sites
● Quadriceps femoris – a group of four large muscles.
● Sartorius
-function: flexes and laterally rotates the hip joint and can flex the knee joint.
-insertion: medial aspect of the proximal tibia
-origination: ASIS
● Iliopsoas
-function: flex hip joint
-insertion: lesser trochanter of the femur
-originationT12-L5 vertebrae
● Pectineus
-function: flexes and adducts hip joint
-insertion: poster femur on pectoral line
-origination: S pubic rami/pubic pectineal line
