Hip & Lower Limb Flashcards
Angle between hip & femur decreases (ex. lifting your leg up)
Hip flexion of Psoas Major
Transverse processes & bodies of L1-L5, intervertebral firbrocartilage of T12-L5
Origin of Psoas Major
Lesser trochanter of femur
Insertion of Psoas Major and Illacus
Flex the spine
Action of Psoas Minor
Angle between spine & hip decreases (taking a bow)
Spinal Flexion of Psoas Minor
Lateral sides of the bodies & intervertebral discs of T12-L1
Origin of Psoas Minor
Pectineal line, iliopectineal eminence, iliac fascia
Insertion of Psoas Minor
Flex the hip (thigh), flexes the spine when the femur is fixed
Action of Illacus & Psoas Major
Upper majority of the iliac fossa
Origin of Illacus
Abducts, extends, and externally rotates the hips
Action of Gluteus Maximus
Posterior gluteal line of the ilium, sacrospinalis aponeurosis, fascia covering gluteus mediums
Origin of Gluteus Maximus
Upper fibers at iliotibial tract of the fascia lata, lower fibers at the gluteal tuberosity
Insertion of Gluteus Maximus
Abduction, internal rotation (anterior portion), external rotation (posterior portion) of the hip
Action of Gluteus Medius
Gluteal surface of the ilium and flute, aponeurosis
Origin of Gluteus Medius
Lateral surface of the greater trochanter of the femur
Insertion of Gluteus Medius
