Questions 76 through 79 refer to the figure below of an MRA of the descending aorta.Which arrow points to the abdominal aorta?
-
D
-
A
-
B
-
C
Correct Answer
A. AExplanation
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.Rate this question:

-
D
-
B
-
C
-
A
Correct Answer
A. AExplanation
In the figure provided, arrow A points to the iliac crest. The iliac crest is the curved ridge at the top of the hip bone, which can be palpated at the side of the body.Rate this question:

Questions 13 through 16 refer to the figure below of a coronal MRI of the female pelvis.Which arrow points to the vagina?
-
D
-
C
-
A
-
B
Correct Answer
A. BExplanation
The arrow pointing to B indicates the vagina. The vagina is a muscular canal that connects the uterus to the external opening of the female genitalia. In the given coronal MRI image, arrow B is located in the lower part of the pelvis, which corresponds to the position of the vagina.Rate this question:

Questions 64 through 67 refer to the figure below of an axial CT of the pelvis.Which arrow points to the external iliac artery?
-
A
-
C
-
D
-
B
Correct Answer
A. AExplanation
The correct answer is A. In the given figure, arrow A points to the external iliac artery. The external iliac artery is a major blood vessel that supplies blood to the lower limbs. It is located in the pelvis and can be identified in the axial CT scan by its position and course.Rate this question:

Which muscle combines with the psoas muscle to form the iliopsoas muscle?
-
Piriformis
-
Rectus abdominis
-
Iliacus
-
Coccygeus
Correct Answer
A. IliacusExplanation
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.Rate this question:

Which of the following is true about the uterus?
-
The myometrium is continuous with the broad ligament
-
The perimetrium of the uterus is the outer layer of mucous membrane
-
The middle layer of the uterus is a thick layer of smooth muscle fibers
-
The endometrium is a type of serous membrane
Correct Answer
A. The middle layer of the uterus is a thick layer of smooth muscle fibersExplanation
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.Rate this question:

Questions 40 through 43 refer to the figure below of an axial, T2-weigted MRI of the male pelvis.Which arrow points to the retropubic space?
-
C
-
B
-
D
-
A
Correct Answer
A. AExplanation
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.Rate this question:

Questions 28 through 31 refer to the figure below of a 3D CT of the pelvis.Which arrow points to the pubic symphysis?
-
C
-
D
-
B
-
A
Correct Answer
A. CExplanation
The correct answer is C. In the figure, arrow C points to the pubic symphysis. The pubic symphysis is the joint between the two pubic bones in the pelvis.Rate this question:

Questions 48 through 51 refer to the figure below of a sagittal, T2-weighted MRI of the male pelvis.Which arrow points to the urogenital diaphragm?
-
D
-
B
-
A
-
C
Correct Answer
A. CExplanation
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.Rate this question:
