what are the ten muscles of the posterior hip?
tensor fascia lata gluteus maximus gluteus medius gluteus minimus piriformis superior gemellus obturator internus inferior gemellus obturator externus quadratus femoris
what is the muscle that lies along the lateral border of the femur, between two layers of the lateral aspect of the fascia lata (illiotibial tract). the muscle forms a superficial elevation below and lateral to the iliac crest?
tensor fascia lata
what is the origin of the tensor fascia lata?
crest of the ilium
what is the insertion of the tensor fascia lata?
iliotibial tract
what muscle flexes, abducts, and medially rotates femur and helps to stabilize the knee joint?
tensor fascia lata
what is the nerve supply of the tensor fascia lata?
superior Gluteal (L4,L5,S1)
what is the largest and most supeficial muscle of the hip region?
gluteus maximus
what is the muscle that is conspicuous in humans for its great bulk, which together with a variable amount of adipose tissue forms the?
gluteus maximus and forms the buttocks
what is the muscle that is the largest by weight in human body and is associated with the assumption of the erect posture and bipedal locomotion?
gluteus maximus
what are the two gluteal bursae?
trochanteric bursae
ischial bursae
there are a number of bursae that separate the gluteus maximus from bone and are collectively known as?
gluteal bursae
what are the three origin points of the gluteus maximus?
posterior gluteal line
sacrum and coccyx
posterior ligaments of the sacroiliac joint
what are the two insertion points of the gluteus maximus?
gluteal tuberosity (line) of femur iliotibial tract
what are the three actions of the gluteus maximus?
- extends and laterally rotates femur
- helps to stabilize the pelvic bone
- stabilizes the knee joint
what is the nerve for the gluteus maximus?
inferior gluteal (L5,S1,S2)
when patients experience a difficulty in getting from a sitting to a standing position (may have to actively push themselves to the standing position), this is due to weakness of what muscle?
gluteus maximus
weakness of what muscle will cause difficulty straightening from a bending position, walking uphill or up stairs?
gluteus maximus
Atrophy of the gluteus maximus does not seriously affect walking on?
level ground or standing still
what is the muscle which is partly deep to the gluteus maximus, but its superior portion remains superficial?
Gluteus medius
origin of the gluteus medius?
external surface of the ilium
insertion of the gluteus medius?
greater trochanter of the femur
what is the smallest of the gluteal muscles and deep to the gluteus medius?
gluteus minimus
origin of the gluteus minimus?
external surface of ilium
insertion of gluteus minimus?
greater trochanter of femur
