Saddle joint is present between …...i…... and hinge joint is present between ......ii…….

Options

A. i. Carpal and metacarpal of thumb , ii : knee joint
B. i: Tarsal ,ii : between radius and ulna
C. i: Carpal and metacarpal of thumb , ii : shoulder
D. i: Hip joint ,ii : wrist

Answer

To solve the question regarding the presence of saddle and hinge joints, we will analyze each part of the question step by step.

### Step-by-Step Solution:

1. **Understanding the Types of Joints**:
- A **saddle joint** allows movement in two planes and is characterized by the interlocking of two bone ends that resemble a saddle.
- A **hinge joint** allows movement primarily in one plane, similar to the way a door opens and closes.

2. **Identifying the Saddle Joint**:
- The question asks where a saddle joint is present. The saddle joint is specifically found between the **carpal and metacarpal bones of the thumb**. This joint allows for the thumb's unique range of motion, including opposition.

3. **Identifying the Hinge Joint**:
- Next, we need to identify where a hinge joint is present. The hinge joint is found in several locations in the body, but the most notable example is the **knee joint**. The knee joint allows for flexion and extension, similar to a hinge.

4. **Evaluating the Options**:
- Now, we will evaluate the provided options:
- **Option 1**: Carpal and metacarpal of thumb (saddle joint) and knee joint (hinge joint) - This is correct.
- **Option 2**: Tarsal and radius/ulna - This is incorrect; the joint between ulna and radius is the distal radio-ulnar joint.
- **Option 3**: Carpal and metacarpal of thumb (saddle joint) and shoulder joint - This is incorrect; the shoulder joint is a ball-and-socket joint.
- **Option 4**: Hip joint and wrist - This is incorrect; the hip joint is also a ball-and-socket joint.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Option 1**, which states that the saddle joint is present between the carpal and metacarpal of the thumb, and the hinge joint is present at the knee joint.

### Final Answer:
**Saddle joint is present between the carpal and metacarpal of the thumb, and hinge joint is present between the knee joint.**
