    O - anterior sacrum, ischial tuberosity, ischial spine, obturator foramen, superior and inferior pubic rami I - greater trochanter

    • Gluteus minimus

    • Deep six external rotators

    • Gluteus medius

    • Psoas major

    Correct Answer
    A. Deep six external rotators
    Explanation
    The deep six external rotators are a group of muscles located in the hip region. These muscles include the piriformis, gemellus superior, gemellus inferior, obturator internus, obturator externus, and quadratus femoris. They are responsible for rotating the thigh externally. In the given list, all the other muscles mentioned (gluteus minimus, gluteus medius, and psoas major) are not part of the deep six external rotators. Therefore, the correct answer is deep six external rotators.

    Rate this question:

  • 3. 

    All the following muscles insert on the greater trochanter EXCEPT

    • Gluteus medius

    • Deep six external rotators

    • Psoas minor

    • Gluteus minimus

    Correct Answer
    A. Psoas minor
    Explanation
    The psoas minor muscle does not insert on the greater trochanter. The gluteus medius, deep six external rotators, and gluteus minimus all have attachments to the greater trochanter. The psoas minor muscle is a small muscle located in the lower back and it inserts on the pectineal line of the pubis.

    Rate this question:

    This muscle is the agonist/primary mover for hip extension

    • Gluteus maximus

    • Gluteus medius

    • Psoas major

    • Gluteus minimus

    Correct Answer
    A. Gluteus maximus
    Explanation
    The gluteus maximus is the correct answer because it is the largest and most powerful muscle in the gluteal region. It is responsible for hip extension, which is the movement of the hip joint that brings the thigh backward. The gluteus maximus contracts to pull the thigh backward, allowing us to stand up from a sitting position, climb stairs, and perform movements like running and jumping. The other muscles listed, gluteus medius, psoas major, and gluteus minimus, are not the primary movers for hip extension.

    O - coccyx, posterior sacrum, iliac crest, sacroiliac and sacrotuberous ligaments I - IT band and gluteal tuberosity

    • Gluteus maximus

    • Gluteus medius

    • Psoas major

    • Iliacus

    Correct Answer
    A. Gluteus maximus
    Explanation
    The gluteus maximus is the correct answer because it is the largest and most superficial muscle of the buttocks. It is responsible for extending and externally rotating the hip joint, as well as assisting in the stabilization of the pelvis. The other muscles listed (gluteus medius, psoas major, and iliacus) are also involved in hip movement, but they do not have as much prominence or play as significant a role as the gluteus maximus. The ligaments and bony structures mentioned in the first part of the question are not directly related to the gluteus maximus muscle.

    Rate this question:

  • 6. 

    The iliopsoas is made up of the following two muscles:

    • Iliacus and psoas minor

    • Ischium and psoas major

    • Iliacus and psoas major

    • Psoas minor and ischium

    Correct Answer
    A. Iliacus and psoas major
    Explanation
    The correct answer is iliacus and psoas major. The iliopsoas is a group of muscles that work together to flex the hip joint. The iliacus muscle is located in the pelvis and attaches to the iliac fossa, while the psoas major muscle is located in the lumbar region of the spine and attaches to the lesser trochanter of the femur. These two muscles work together to flex the hip joint and are commonly referred to as the iliopsoas.

    Rate this question:

  • 7. 

    40% of the population has this muscle

    • Psoas major

    • Gluteus minimus

    • Iliacus

    • Psoas minor

    Correct Answer
    A. Psoas minor
    Explanation
    The psoas minor muscle is the correct answer because it is estimated that 40% of the population has this muscle. The psoas minor muscle is a small muscle located in the lower back and connects the lumbar vertebrae to the pelvis. It is not as well-known or commonly discussed as the other muscles listed, such as the psoas major, gluteus minimus, or iliacus. However, it is still present in a significant portion of the population.

    • Gluteus maximus

    • Psoas major

    • Gluteus minimus

    • Gluteus medius

    Correct Answer
    A. Psoas major
    Explanation
    The psoas major is the correct answer because it is the only muscle listed that is located in the area of the lesser trochanter. The gluteus maximus, gluteus minimus, and gluteus medius are all muscles of the gluteal region and are not directly associated with the lesser trochanter.

    Rate this question:

    These two muscles attach to the IT band

    • Gluteus minimus and TFL

    • TFL and gluteus medius

    • Gluteus maximus and TFL

    • Gluteus maximus and psoas major

    Correct Answer
    A. Gluteus maximus and TFL
    Explanation
    The gluteus maximus and TFL (tensor fasciae latae) muscles attach to the IT band. The gluteus maximus is the largest muscle in the buttocks and is responsible for hip extension and external rotation. The TFL is a small muscle located on the outside of the hip and is responsible for hip flexion, abduction, and internal rotation. Both of these muscles play a role in stabilizing the IT band, a thick band of connective tissue that runs along the outside of the thigh.

    Normal ROM for hip flexion

    • 120

    • 90

    • 35

    • 45

    Correct Answer
    A. 120
    Explanation
    The given numbers represent the range of motion (ROM) for hip flexion. The correct answer is 120, which indicates that the normal ROM for hip flexion is 120 degrees. This means that a person should be able to flex their hip joint up to 120 degrees without any restrictions or limitations.

  • 11. 

    Normal ROM for hip abduction

    • 10 - 20

    • 45 - 50

    • 90

    • 120

    Correct Answer
    A. 45 - 50
    Explanation
    The normal range of motion (ROM) for hip abduction is typically between 45 and 50 degrees. This means that the hip joint can move outward from the body to a certain degree within this range. It is important for the hip joint to have a good range of motion in order to perform activities such as walking, running, and climbing stairs. If the ROM for hip abduction falls within this range, it indicates that the hip joint is functioning properly.

    • Psoas major

    • Psoas minor

    • Iliacus

    • Iliopsoas

    Correct Answer
    A. Psoas minor
    Explanation
    The correct answer is psoas minor because it is one of the muscles mentioned in the given list. The psoas minor is a small muscle located in the lower abdomen that runs alongside the psoas major and iliacus muscles. It originates from the bodies of the T12 and L1 vertebrae and inserts into the superior ramus of the pubis. It assists in flexing the hip joint and stabilizing the lumbar spine.

    Normal ROM for hip adduction

    • 20 - 30

    • 45

    • 120

    • 45 - 50

    Correct Answer
    A. 20 - 30
    Explanation
    The normal range of motion (ROM) for hip adduction is typically between 20 and 30 degrees. This means that a person should be able to bring their hip towards the midline of their body by approximately 20 to 30 degrees. This range of motion allows for proper movement and function of the hip joint.

    Rate this question:

  • 15. 

    This muscle is the agonist for hip flexion

    • Gluteus maximus

    • Gluteus minimus

    • Psoas major

    • TFL

    Correct Answer
    A. Psoas major
    Explanation
    The psoas major muscle is the agonist for hip flexion. It is located deep within the abdomen and runs from the lower spine to the thigh bone. When this muscle contracts, it pulls the thigh bone upward, causing flexion at the hip joint. The gluteus maximus and gluteus minimus are both hip extensors, meaning they work opposite to hip flexion. The TFL (tensor fasciae latae) is a muscle located on the side of the hip and is primarily responsible for hip abduction and flexion. Therefore, the psoas major is the correct answer as it is the primary muscle involved in hip flexion.

    When tight, these two muscles can cause a pelvis to tilt anteriorly, causing the lumbar curve to become hyperlordotic

    • Iliacus and psoas major

    • Gluteus maximus and iliacus

    • Psoas minor and gluteus minimus

    • Deep six external rotators and psoas major

    Correct Answer
    A. Iliacus and psoas major
    Explanation
    The iliacus and psoas major muscles are located in the front of the hip and are commonly referred to as the iliopsoas. When these muscles become tight, they can pull on the front of the pelvis, causing it to tilt forward. This anterior tilt of the pelvis can lead to an exaggerated lumbar curve, known as hyperlordosis. Therefore, the iliacus and psoas major muscles can cause the lumbar curve to become hyperlordotic when they are tight.

    Rate this question:

  • 17. 

    Normal ROM for hip internal rotation

    • 0 - 5

    • 35

    • 90

    • 120

    Correct Answer
    A. 35
    Explanation
    The given range of motion (ROM) values represent the degrees of hip internal rotation. The normal ROM for hip internal rotation is typically between 0 and 35 degrees. This means that a healthy hip joint should be able to rotate inward up to 35 degrees. The other values mentioned (90 and 120 degrees) are not within the normal range for hip internal rotation, indicating limited or excessive motion. Therefore, the correct answer is 35.

    Rate this question:

  • 18. 

    These two muscles are agonists for hip abduction

    • Gluteus maximus and gluteus medius

    • Gluteus maximus and gluteus minimus

    • Gluteus minimus and gluteus medius

    • Gluteus medius and adductor longus

    Correct Answer
    A. Gluteus minimus and gluteus medius
    Explanation
    The gluteus minimus and gluteus medius muscles are agonists for hip abduction. This means that they work together to move the hip joint away from the midline of the body. The gluteus minimus is a smaller muscle located deep in the buttocks, while the gluteus medius is a larger muscle located on the outer surface of the hip. Both muscles play a role in stabilizing the pelvis and controlling movement of the hip during activities such as walking or running.

    • Gluteus minimus

    • Gluteus medius

    Correct Answer
    A. Gluteus medius
    Explanation
    The gluteus medius muscle originates from the iliac crest between the superior and middle gluteal lines and inserts on the greater trochanter. This muscle is responsible for abduction and medial rotation of the hip joint. The other muscles listed, such as the gluteus maximus, psoas major, and gluteus minimus, have different origins and insertions and perform different actions.

    • Piriformis, quadratus femoris, obturator externus

    • Inferior gemellus, quadratus femoris, obturator femoris

    Correct Answer
    A. Inferior gemellus, quadratus femoris, obturator femoris
    Explanation
    The correct answer is "inferior gemellus, quadratus femoris, obturator femoris". The question is asking for the muscles that do not form the deep six. The deep six muscles are piriformis, superior gemellus, obturator externus, obturator internus, quadratus femoris, and inferior gemellus. Therefore, the muscles listed in the answer choice are the ones that do not form the deep six.

    • Femoral triangle

    • Pes anserine

    • Pes planus

    • Pes aspera

    Correct Answer
    A. Pes anserine
    Explanation
    The pes anserine is the correct answer because it refers to the area on the proximal medial tibia where the gracilis, sartorius, and semitendinosus muscles attach. This area is located just below the knee joint and is named after the resemblance of the tendons to a goose's foot (pes anserinus in Latin). The pes anserine is important for stabilizing the knee joint and assisting in movements such as flexion and medial rotation of the lower leg.
