The lymph nodes of the neck can be classified or divided into how many levels or regions for ease of identification?
- A.
  
  5
- B.
  
  6
- C.
  
  7
- D.
  
  8
Correct Answer
C. 7

Explanation
The lymph nodes of the neck can be classified into seven levels or regions for ease of identification.

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

Explanation
The correct answer is A because it is pointing to the structure that represents the thecal sac in the axial T2-weighted MRI image of the lumbar vertebra. The thecal sac is a membrane-filled sac that surrounds the spinal cord and contains cerebrospinal fluid. In this image, arrow A is pointing to a clearly visible structure that is located in the center and has a similar signal intensity to the cerebrospinal fluid, indicating that it is the thecal sac.

Explanation
The arrow pointing to D indicates the epiglottis. The epiglottis is a flap of cartilage located at the base of the tongue that prevents food and liquid from entering the trachea during swallowing. In the given figure, D is the only arrow pointing to a structure that resembles the shape and position of the epiglottis. Therefore, D is the correct answer.

Explanation
The correct answer is B because it is pointing to the structure that is most consistent with the internal jugular vein based on its location and anatomical features. The internal jugular vein is located in the neck and runs parallel to the carotid artery. It is larger and more centrally located compared to the other structures shown in the figure. Therefore, arrow B is the most likely to be pointing to the internal jugular vein.
