1.

The most anterior portion of the iliac crest is the:
- A.
  
  Iliopubic eminence
- B.
  
  Pubic tubercle
- C.
  
  Anterior superior iliac spine
- D.
  
  Lliac fossa
Correct Answer
C. Anterior superior iliac spine

Explanation
The anterior superior iliac spine is the correct answer because it is the most anterior part of the iliac crest. It is a bony prominence located at the front of the iliac crest and serves as an attachment point for various muscles and ligaments, including the inguinal ligament. The iliac fossa is a concave area on the inner surface of the ilium, while the iliac tubercle and pubic tubercle are different anatomical landmarks not directly related to the iliac crest.

Questions 18 through 21 refer to the figure below of an axial MRI of the female pelvis.Which arrow points to the piriformis muscle?
- A.
  
  D
- B.
  
  B
- C.
  
  C
- D.
  
  A
Correct Answer
B. B

Explanation
The correct answer is B. In the figure, the arrow labeled B points to the piriformis muscle. The piriformis muscle is a small muscle located deep in the buttocks, and it plays a role in hip rotation and stability. In this axial MRI of the female pelvis, the arrow is indicating the location of the piriformis muscle.

  D
- C.
  
  B
- D.
  
  A
Correct Answer
C. B

Explanation
The levator ani muscle is a group of muscles that supports the pelvic organs. In the given axial, T2-weighted MRI of a female pelvis, arrow B points to the levator ani muscle.

Spermatozoa are produced in the epididymis.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Spermatozoa are not produced in the epididymis. The epididymis is a coiled tube located on the back of each testicle, where sperm are stored and matured. Spermatozoa are actually produced in the testes within structures called the seminiferous tubules.

Of the following structures, which one is most lateral?
- A.
  
  Labia majora
- B.
  
  Clitoris
- C.
  
  Labia minora
- D.
  
  Mons pubis
Correct Answer
A. Labia majora

Explanation
The labia majora is the most lateral structure among the given options. The labia majora are the outer folds of skin and tissue located on either side of the vaginal opening. They are the largest and most visible part of the external female genitalia and are positioned on the outermost sides. The clitoris, labia minora, and mons pubis are also part of the external female genitalia, but they are not as laterally positioned as the labia majora.

What structure serves as the topographic landmark marking the posterior prostate inmales and the vaginal vault in females during a rectal exam?
- A.
  
  Perineal flexure
- B.
  
  Internal anal sphincter
- C.
  
  Transverse rectal fold
- D.
  
  Rectal ampulla
Correct Answer
C. Transverse rectal fold

Explanation
The transverse rectal fold serves as the topographic landmark marking the posterior prostate in males and the vaginal vault in females during a rectal exam. This fold is a ridge-like structure that can be felt during the examination and helps to locate and assess the surrounding structures accurately. It is an important reference point for medical professionals performing rectal exams to ensure proper evaluation and diagnosis.

What structure is located within the inguinal canal in females?
- A.
  
  Suspensory ligament of the ovary
- B.
  
  Round ligament
- C.
  
  Cardinal ligament
- D.
  
  Uterosacral ligament
Correct Answer
B. Round ligament

Explanation
The round ligament is located within the inguinal canal in females. It is a structure that connects the uterus to the labia majora. During fetal development, the round ligament helps guide the descent of the ovaries into the pelvis. In adult females, it helps to support the uterus and maintain its position. It also plays a role in stabilizing the uterus during movements and activities.

  C
- B.
  
  B
- C.
  
  D
- D.
  
  A
Correct Answer
B. B

Explanation
In the given axial T2-weighted MRI of the male pelvis, arrow B points to the obturator externus muscle. This muscle is located in the pelvic region and helps in the external rotation of the thigh. It originates from the obturator foramen and inserts into the trochanteric fossa of the femur. It is important for stabilizing the hip joint and assisting in movements of the thigh.
