    Which of the following is true about the uterus?

    • A.

      The myometrium is continuous with the broad ligament

    • B.

      The perimetrium of the uterus is the outer layer of mucous membrane

    • C.

      The middle layer of the uterus is a thick layer of smooth muscle fibers

    • D.

      The endometrium is a type of serous membrane

    Correct Answer
    C. The middle layer of the uterus is a thick layer of smooth muscle fibers
    Explanation
    The middle layer of the uterus is known as the myometrium, and it is indeed a thick layer of smooth muscle fibers. These muscle fibers are responsible for the contractions of the uterus during childbirth and menstruation. The myometrium is sandwiched between the outer layer called the perimetrium and the inner layer called the endometrium. The perimetrium is not a mucous membrane, but a serous membrane that covers the outer surface of the uterus. Therefore, the statement that the middle layer of the uterus is a thick layer of smooth muscle fibers is true.

    • C.

      D

    • D.

      A

    Correct Answer
    D. A
    Explanation
    The correct answer is A. The retropubic space is located behind the pubic bone and in front of the bladder. In the given MRI image, arrow A points to this space, indicating that it is the correct answer. The other arrows (B, C, and D) do not point to the retropubic space.

      B

    • D.

      C

    Correct Answer
    B. A
    Explanation
    The correct answer is A because it points to the abdominal aorta. The descending aorta is divided into two parts: the thoracic aorta and the abdominal aorta. The thoracic aorta extends from the aortic arch to the diaphragm, while the abdominal aorta starts at the diaphragm and continues down to the pelvis. Therefore, arrow A correctly points to the abdominal aorta in the given figure.

    Which muscle combines with the psoas muscle to form the iliopsoas muscle?

    • A.

      Piriformis

    • B.

      Rectus abdominis

    • C.

      Iliacus

    • D.

      Coccygeus

    Correct Answer
    C. Iliacus
    Explanation
    The correct answer is Iliacus. The iliopsoas muscle is formed by the combination of the psoas muscle and the iliacus muscle. The psoas muscle originates from the lumbar vertebrae and the iliacus muscle originates from the iliac fossa of the pelvis. These two muscles come together and merge to form the iliopsoas muscle, which plays a major role in hip flexion and stabilization of the lumbar spine. The piriformis, rectus abdominis, and coccygeus muscles are not involved in the formation of the iliopsoas muscle.

    The correct answer is C. In the given figure, the arrow labeled C points to the urogenital diaphragm. The urogenital diaphragm is a muscular structure located in the pelvis that separates the urogenital and anal triangles. It provides support to the pelvic organs and plays a role in controlling urinary and fecal continence.
