Gluetal Region Flashcards
Tensor fasciae latae insertion
Iliotibial tract (aka IT band)
Tensor fasciae latae origin
ASIS
Tensor fasciae latae innervation
Superior gluteal nerve
Tensor fasciae latae action
Stabilizes pelvis and helps to keep the knee extended by tensing the IT tract
Gluteus maximus origin
Sacrum, ilium (medial to posterior gluteal line), sacrotuberous ligament
Gluteus maximus insertion
Iliotibial tract, gluteal tuberosity
Gluteus maximus innervation
Inferior gluteal nerve
Gluteus maximus action
Laterally rotates thigh at hip joint; extends thigh at hip joint, especially when flexed or working against resistance
Gluteus medius origin
Ilium between anterior & posterior gluteal lines
Gluteus medius insertion
Greater trochanter of femur
Gluteus medius innervation
Superior gluteal nerve
Gluteus medius action
Abducts and medially rotates thigh at hip joint; steadies pelvis on leg when opposite leg is raised
Gluteus minimus origin
Ilium between anterior & inferior gluteal lines
Gluteus minimus insertion
Greater trochanter of femur
Gluteus minimus innervation
Superior gluteal nerve
Gluteus minimus action
Abducts and medially rotates thigh at hip joint; steadies pelvis on leg when opposite leg is raised
Piriformis origin
Anterior part of sacrum
Piriformis insertion
Femur, greater trochanter
Piriformis innervation
Sacral plexus
Piriformis action
Laterally rotates thigh at hip joint
Gemelli (superior and inferior) origin
Lesser sciatic notch
Gemelli insertion
Femur, greater trochanter
Gemelli innervation
Sacral plexus
Gemelli action
Laterally rotates thigh at hip joint
Obturator internus origin
Internal surface of obturator membrane
Obturator internus insertion
Femur, greater trochanter
Obturator internus innervation
Sacral plexus
Obturator internus action
Laterally rotates thigh at hip joint
Quadratus femoris origin
Ischial tuberosity
Quadratus femoris insertion
Quadrate tubercle of femur
Quadratus femoris innervation
Sacral plexus
Quadratus femoris action
Laterally rotates thigh at hip joint
