BIO-MTH

The muscles of the pelvis and hip

QuestionAnswer
Gluteal Muscles Gluteus maximus Gluteus medius Gluteus minimus Deep rotators Tensor fascia latae
The largest and most superficial of the gluteal muscles Gluteus Maximus
What is the proximal attachment for gluteus maximus? Posterior sacrum and ilium
What is the distal attachment for gluteus maximus? Posterior femur distal to greater trochanter
What is the action of gluteus maximus? Hip extension and external rotation, Pelvic posterior tilt and posterior rotation
A triangular shaped muscle That covers the outer surface of the ilium Gluteus Medius
What is the proximal attachment of gluteus medius? The outer surface of the ilium
What is the distal attachment of gluteus medius? The lateral surface of the greater trochanter
What action does the gluteus medius achieve? Hip abduction and pelvis elevation
When walking what keep pelvis level during unilateral stance? Gluteus Medius
A fan-shaped muscle that extends from the outer surface of the ilium to the anterior surface of the greater trochanter of the femur Gluteus Minimus
What helps the glutues medius to stabilizes the pelvis when balancing on one leg, making it an important during walking and running? Gluteus Minimus
Which gluteal muscle becomes tight, pulls on the pelvis and can cause pelvic and back pain? Minimus
What is the proximal attachment of gluteus minimus? Outer surface of ilium
What is the distal attachment of gluteus minimus? Anterior surface of the greater trochanter
What action does the gluteus minimus achieve? Hip abduction and internal rotation, Pelvic elevation and anterior rotation
What are the six lateral rotators of the hip? Piriformis, Gemellus superior, Obturator internis, Obturator externus (deep), Gemellus inferior , Quadratus femoris
What are the hip flexors? Iliacus and Psoas (Iliopsoas)
What is the proximal attachments of iliopsoas? Iliacus: Iliac fossa Psoas: T12-L5
What is the distal attachments of iliopsoas? Lesser trochanter of the femur
What action does the iliopsoas achieve? Hip flexion and Pelvic anterior tilt
Together, the TFL muscle and the continuation of the fascia lata are called the Iliotibial band (IT)
A short muscle with a long tendinous attachment Tensor fascia lata (TFL)
What is the proximal attachments of TFL? ASIS
What is the distal attachments of TFL? Deep fascia of the lateral leg
What action does the TFL achieve? Combined hip flexion and abduction

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
