Find the mismatch from the following pairs.

Options

A. Joint between carpel and metacarpal of thumb - Gliding joint
B. Joint between humerus and pectoral girdle - Ball and socket joint .
C. Hinge joint - joint in the elbows
D. Joint between atlas and axis - pivot joint

Answer

To solve the question of finding the mismatch from the given pairs, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Identify the First Pair:**
- **Joint Type:** Gliding Joint
- **Location:** Between carpal and metacarpal bones.
- **Analysis:** The joint between the carpal and metacarpal bones is specifically called the carpometacarpal joint, which is a type of synovial joint. Therefore, this pair is mismatched.

2. **Identify the Second Pair:**
- **Joint Type:** Ball and Socket Joint
- **Location:** Between humerus and pectoral girdle.
- **Analysis:** The joint between the humerus and the pectoral girdle is indeed a ball and socket joint, which allows for a wide range of motion. This pair is correctly matched.

3. **Identify the Third Pair:**
- **Joint Type:** Hinge Joint
- **Location:** In the elbow.
- **Analysis:** The elbow joint is a classic example of a hinge joint, allowing for flexion and extension. This pair is also correctly matched.

4. **Identify the Fourth Pair:**
- **Joint Type:** Pivot Joint
- **Location:** Between atlas and axis (the first two cervical vertebrae).
- **Analysis:** The joint between the atlas and axis is indeed a pivot joint, allowing for rotational movement of the head. This pair is correctly matched.

### Conclusion:
After analyzing all pairs, the only mismatched pair is the first one, which incorrectly identifies the joint between the carpal and metacarpal bones as a gliding joint instead of the correct term, carpometacarpal joint.

### Final Answer:
The mismatched pair is the first option: **Joint between carpal and metacarpal - Gliding Joint.**
