Question

Match List I with List II.

List I	List II
A. Superior zygapophyseal facets of cervical vertebrae B. Inferior zygapophyseal facets of cervical vertebrae C. Superior zygapophyseal facets of thoracic vertebrae D. Superior zygapophyseal facets of lumbar vertebrae	I. Face posteriorly, superiorly and laterally II. Face posteromedially III. Face superiorly and medially IV. Face anteriorly and laterally

Choose the correct answer from the options given below:

• A. A-I, B-II, C-III, D-IV
• B. A-IV, B-III, C-I, D-II
• C. A-III, B-IV, C-I, D-II
• D. A-II, B-IV, C-I, D-III

Hint:

Spine rule: Cervical = oblique, Thoracic = coronal, Lumbar = sagittal orientation

Answer 1

The Correct Option is C

Concept:
Zygapophyseal (facet) joints vary in orientation in different regions of the spine to allow specific movements and provide stability.

Step 1: Cervical vertebrae facets.

• Superior facets face superiorly and posteriorly (often medially inclined)
• Inferior facets face anteriorly and laterally Thus: \[ A \rightarrow III, \quad B \rightarrow IV \]

Step 2: Thoracic vertebrae facets.

• Superior facets face posteriorly, superiorly and laterally Thus: \[ C \rightarrow I \]

Step 3: Lumbar vertebrae facets.

• Superior facets face medially (posteromedially) Thus: \[ D \rightarrow II \]

Step 4: Final mapping.
\[ A\!-\!III,\; B\!-\!IV,\; C\!-\!I,\; D\!-\!II \] \[ \boxed{\text{Correct answer = Option (3)}} \]
