Muscle Atlas

Origin: Iliac fossa & crest ala of sacrum Insertion: lesser trochanter of femur Action: Prime mover of thigh flexion

Origin: transverse processes, bodies and discs of lumbar vertebrae and T12 Insertion: Lesser trochanter of femur Action: Prime mover for flexing thigh

Origin:Anterior superior iliac spine Insertin:Winds around medial aspect of knee and inserts into medial aspect of proximal tibia. Action: Flexes, abducts and laterally rotates thigh; flexes knee – crossing legs.

Origin: iliac crest & lumbar fascia Insertion:Transverse processes of lumbar vertebrae L1-L4 & lower margin of 12^th rib. Action:Flexes vertebral column laterally

origin:Ischial and pubic rami and ischial tuberosity insertion:Linea aspera and adductor tubercle of femur action:Anterior part – adductos and medially rotates and flexes thigh, posterior part is a synergist of hamstrings in thigh extension
