Gluteal region and Hip Flashcards
gluteus maximus O
ilium posterior to posterior gluteal line
dorsal surface of sacrum and coccyx
sacrotuberous ligament
glut max I
fibers end in iliotibial tract, these fibers insert into lateral condyle of tibia
fibers insert on gluteal tuberosity of femur
glut max innervation
inferior gluteal nerve (L5, S1, S2)
glut max action
extends hip joint between flexed and standing positions
assists in lateral rotation
steadies thigh and assists in rising from sitting position
glut med O
external surface of ilium between anterior and posterior gluteal lines
glut med I
lateral surface of greater trochanter of femur
glut med innervation
superior gluteal nerve (L4, L5, S1)
glut med action
abduct and anterior portions medially rotate hip joint
keep pelvis level when opposite limb is elevated
glut min O
external surface of ilium between anterior and inferior gluteal lines
glut min I
anterior surface of greater trochanter of femur
glut min innervation
superior gluteal nerve (L4,L5,S1)
glut min action
abduct and anterior portions of medially rotates hip joint
keep pelvis level when opposite limb is elevated
gemelli superior and inferior O
superior: ischial spine
inferior: ischial tuberosity
gemellia superior and inferior I
medial surface of greater trochanter (trochanteric fossa) of femur
gemelli superior and inferior innervation
superior: nerve to obturator internus (L5,S1)
inferior: nerve to quadratus femoris (L5,S1)
gemelli superior and inferior action
laterally roatte extended hip joint
abduct flexed hip joint
teady femoral head in acetabulum
quadratus femoris O
lateral border of ischial tuberosity
quadratus femoris I
quadrate tubercle of intertrochanteric crest of femur and area inferior to it
quadratus femoris innervation
nerve to quadratus femoris (L5, S1)
quadratus femoris action
laterally rotates hip joint
pulls femoral had into acetabulum to stabilize hip joint/ pelvis
tensor fascia lata O
anterior superior iliac spine
anterior part of iliac crest
tensor fascia lata I
iliotibial tract
which attaches to lateral condyle of tibia (gerdy tubercle)
tensor fascia innervation
superior gluteal nerve (L4,L5,S1)
tensor fascia action
flexes hip joint
acts with gluteal maximus to stabilize the extended knee joint
piriformis O
ant surface 2nd-4th sacral segments
superior margin of greater sciatic notch
sacrotuberous ligament
piriformis I
superior border of greater trochanter of femur
pirifmoris innervation
branches of ant rami S1,S2
piriformis acrion
laterally rotates extended hip joint
abducts flexed hip
steadies femoral head in acetabulum
obturator internus O
pelvic surface of ilium and ischium
obturator foramen
obturator internus I
trochanteric fossa of femur
obturator internus innervation
nerve to obturator internus L5,S1
obturator internus action
laterally rotates extended hip joint
abducts flexed hip joint
steadies femoral head in acetabulum
