Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Always associate pivot-type movement (like shaking the head "no" at the atlanto-axial joint) with Trochoid, and ball-and-socket movement (like the shoulder) with Enarthrosis.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Joints (articulations) in domestic animals are classified based on their structural design and the type of movement they permit.

Step 2: Detailed Explanation:
Let us pair each joint with its correct classification:
- A. Carpo-metacarpal joint: A gliding joint allowing minimal shifting movements. This is classified as an Arthrodia (plane joint). This matches with III.
- B. Atlanto-occipital joint: The "yes-joint" allowing primarily flexion and extension of the head. This is classified as a Ginglymus (hinge joint). This matches with IV.
- C. Atlanto-axial joint: The "no-joint" allowing rotation of the atlas around the dens of the axis. This is classified as a Trochoid (pivot joint). This matches with II.
- D. Shoulder joint (Scapulohumeral joint): A multiaxial joint allowing rotation and movement in all directions. This is classified as an Enarthrosis (ball-and-socket joint). This matches with I.
Therefore, the correct combination is A - III, B - IV, C - II, D - I.

Step 3: Final Answer
The correct option is (A).
