Questions and Answers
  • 1. 

    What is the action of the iliopsoas muscle?

    • A.

      Thigh flexion

    • B.

      Thigh adduction

    • C.

      Lateral rotation of the thigh

    • D.

      Abduction of flexed thigh

    • E.

      Stabilizing the femoral head in the acetabulum

    Correct Answer
    A. Thigh flexion
    Explanation
    The action of the iliopsoas muscle is thigh flexion. This muscle is a combination of two muscles, the iliacus and the psoas major, which work together to flex the thigh at the hip joint. Thigh flexion refers to the movement of bringing the thigh towards the abdomen. The iliopsoas muscle is responsible for this movement, allowing us to lift our leg and bring our knee towards our chest.

    What are the attachments of the adductor longus muscle (two answers)?

    • A.

      Inferior ramus of the pubis

    • B.

      Middle 1/3 of the linea aspera

    • C.

      Pectineal line

    • D.

      Pubis inferior to pubic crest

    • E.

      Ischial tuberosity

    Correct Answer(s)
    B. Middle 1/3 of the linea aspera
    D. Pubis inferior to pubic crest
    Explanation
    The attachments of the adductor longus muscle include the middle 1/3 of the linea aspera and the pubis inferior to the pubic crest. These are the two specific points where the muscle originates or attaches to. The other options mentioned, such as the inferior ramus of the pubis, pectineal line, and ischial tuberosity, are not the attachments of the adductor longus muscle.

      Fibularis longus

    Correct Answer(s)
    C. Gastrocnemius
    D. Tibialis posterior
    E. Fibularis longus
    Explanation
    The gastrocnemius, tibialis posterior, and fibularis longus muscles all aid in plantar flexion of the ankle. The gastrocnemius is a large calf muscle that helps to push the foot downward, while the tibialis posterior is located on the back of the leg and assists in both plantar flexion and inversion of the foot. The fibularis longus, also known as the peroneus longus, is located on the outer side of the lower leg and helps to turn the foot outward and downward.

  • 6. 

    Which does not affect lateral rotation of an extended thigh?

    • A.

      Piriformis

    • B.

      Obturator internus

    • C.

      Superior and inferior gemelli

    • D.

      Gluteus minimus

    • E.

      Gluteus maximus

    Correct Answer
    D. Gluteus minimus
    Explanation
    The gluteus minimus is a small muscle located in the buttocks. It is responsible for various movements of the hip joint, including abduction and medial rotation. However, it does not play a significant role in lateral rotation of an extended thigh. Lateral rotation of the extended thigh is primarily controlled by the piriformis, obturator internus, and the superior and inferior gemelli muscles. The gluteus maximus, on the other hand, is responsible for extension and lateral rotation of the hip joint, but it is not specifically involved in lateral rotation of an extended thigh.

    Which muscles attach proximally on the ASIS? (Select all that apply)

    • A.

      Sartorius

    • B.

      Rectus femoris

    • C.

      Pectineus

    • D.

      Vastus lateralis

    • E.

      Tensor fascia latta

    Correct Answer(s)
    A. Sartorius
    B. Rectus femoris
    E. Tensor fascia latta
    Explanation
    The muscles that attach proximally on the ASIS (anterior superior iliac spine) are the sartorius, rectus femoris, and tensor fascia lata. The sartorius muscle originates from the ASIS and runs down the thigh. The rectus femoris muscle also originates from the ASIS and is one of the quadriceps muscles. The tensor fascia lata muscle originates from the ASIS and inserts into the iliotibial tract. These muscles play a role in various movements of the hip and thigh.

  • 11. 

    Which muscle flexes, abducts and laterally rotates the thigh at the hip joint?

    • A.

      Pectineus

    • B.

      Sartorius

    • C.

      Iliopsoas

    • D.

      Tensor fascia lata

    • E.

      Gluteus minimus

    Correct Answer
    B. Sartorius
    Explanation
    The sartorius muscle is responsible for flexing, abducting, and laterally rotating the thigh at the hip joint. It is the longest muscle in the body and runs diagonally across the front of the thigh. Its actions allow for movements such as crossing the legs and sitting cross-legged. The other options listed are not involved in all three of these movements.

    Rate this question:

  • 12. 

    Which muscle has attachments at the perineal body and and the internal surface of the ischial tuberosity and ischiopubic ramis?

    • A.

      Ischiocavernosis

    • B.

      Transverse perineal

    • C.

      Bulbospongiosus

    • D.

      Pubococcygeus

    • E.

      Iliococcygeus

    Correct Answer
    B. Transverse perineal
    Explanation
    The transverse perineal muscle is the correct answer because it has attachments at the perineal body, which is located between the anus and the vagina in females or the scrotum in males, and the internal surface of the ischial tuberosity and ischiopubic ramus. This muscle helps to support the pelvic organs and aids in maintaining continence.

  • 13. 

    Which is not innervated by the tibial nerve?

    • A.

      Plantarus

    • B.

      Poplitius

    • C.

      Tibialis anterior

    • D.

      Tibialis posterior

    • E.

      Gastrocnemius

    Correct Answer
    C. Tibialis anterior
    Explanation
    The tibialis anterior muscle is innervated by the deep fibular nerve, not the tibial nerve. The deep fibular nerve is a branch of the common fibular nerve, which is a branch of the sciatic nerve. The tibial nerve, on the other hand, innervates the tibialis posterior, plantaris, gastrocnemius, and popliteus muscles. Therefore, the tibialis anterior is the correct answer as it is not innervated by the tibial nerve.

    Which of the following muscles extends the thigh and rotates the thigh medially when the knee is flexed?

    • A.

      Semitendinosus

    • B.

      Semimembranosus

    • C.

      Biceps femoris

    • D.

      Obturator externus

    • E.

      Gracilus

    Correct Answer(s)
    A. Semitendinosus
    B. Semimembranosus
    Explanation
    The semitendinosus and semimembranosus muscles are both part of the hamstring group and are responsible for extending the thigh and rotating it medially when the knee is flexed. The biceps femoris muscle is also part of the hamstring group but it is responsible for extending the thigh and rotating it laterally when the knee is flexed. The obturator externus muscle is not involved in thigh extension or medial rotation. The gracilis muscle is responsible for adduction of the thigh, not extension or medial rotation.

  • 15. 

    Which of the following is not innervated by the superior gluteal nerve?

    • A.

      Gluteus maximus

    • B.

      Gluteus medius

    • C.

      Gluteus minimus

    • D.

      Tensor fascia lata

    Correct Answer
    A. Gluteus maximus
    Explanation
    The gluteus maximus is not innervated by the superior gluteal nerve. The superior gluteal nerve primarily innervates the gluteus medius, gluteus minimus, and tensor fascia lata muscles. The gluteus maximus, on the other hand, is innervated by the inferior gluteal nerve.
