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
Abduction, internal rotation (anterior portion), external rotation (posterior portion) of the hip
Action of Gluteus Minimus
Gluteal surface of the ilium (inferior to glute medius origin)
Origin of Gluteus Minimus
Anterior surface of the greater trochanter of the femur
Insertion of Gluteus Minimus
Tenses fascia lata, abducts & internally rotates the hip, stabilizes the hip & knee
Action of Tensor Fasciae Latae
Anterior superior iliac spine
Origin of Tensor Fasciae Latae
Iliotibial tract
Insertion of Tensor Fasciae Latae
Externally rotates & abducts the hip
Action of Quadratus Femoris
External border of the Ischial tuberosity
Origin of Quadratus Femoris
Intertochanteric crest of the femur
Insertion of Quadratus Femoris
Externally rotates, abducts, & extended the hip, stabilizes the hip
Action of Piriformis
Front of the sacrum between S1-S4 anterior sacral foramina
Origin of Piriformis
Upper border of the greater trochanter of the femur
Insertion of Piriformis
Extended the knee & flexes the hip
Action of Rectus Femoris
Anterior inferior iliac spine, groove superior to the acetabulum
Origin of Rectus Femoris
Common tendon of the quadriceps inserting on the tibial tuberosity
Insertion of Rectus Femoris
Extends the knee
Action of Vastus Lateralis and Vastus Medialis and Vastus Intermedius
Greater trochanter and upper lateral surface of the linea aspera
Origin of Vastus Lateralis
Patella via the quadriceps tendon, tibial tuberosity via the patellar ligament
Insertion of Vastus Lateralis and Vastus Medialis
Intertrochanteric line and medial lip of the linea aspera
Origin of Vastus Medialis
Upper portion of the anterior & lateral surface of the femur
Origin of Vastus Intermedius
Flexes, abducts & externally rotates the hip, flexes & internally rotates the knee
Action of Satorius
Adducts & medially rotates the hip
Adductors (Longus & Brevis)
Both heads flex & externally rotate the knee, long head also extends the hip
Biceps Femoris (Long & Short Heads)
Flexes & internally rotates the knee
Semimembranosus
