An athlete while running fell on the track. She used her hands to sustain minimal injury. In the process, her hands received the maximum blow on the joints. Which combination of joints would be badly affected in this accident ?

Options

A. Cartilaginous and synaptic joints
B. Fibrous and cartilaginous joints
C. Fibrous and synovial joints
D. Cartilaginous and synovial joints

Answer

To determine which combination of joints would be badly affected in the athlete's accident, we need to analyze the types of joints involved when she fell and used her hands to break the fall.

### Step-by-Step Solution:

1. **Identify the Joints in the Hands**:
- The hands contain several types of joints, primarily synovial joints. These joints allow for a wide range of motion and are crucial for the functioning of the hands.

2. **Consider the Impact on the Joints**:
- When the athlete fell and used her hands to brace herself, the joints in her hands would have absorbed a significant amount of force. The most affected joints would likely be the ones that are most mobile and bear the brunt of the impact.

3. **Types of Joints**:
- **Synovial Joints**: These are freely movable joints and include the joints in the fingers, wrists, and elbows. They are likely to be affected due to their range of motion and the force applied during the fall.
- **Cartilaginous Joints**: These joints are less mobile and are not present in the hands. Therefore, they would not be affected in this scenario.
- **Fibrous Joints**: These joints are immovable and are found in areas such as the skull. They are not relevant to the injury sustained by the athlete.

4. **Conclusion**:
- The most likely combination of joints that would be badly affected in this accident are the **synovial joints in the hands and possibly the elbow**. These joints are designed for movement and would experience the maximum stress during the fall.

### Final Answer:
The combination of joints that would be badly affected in this accident are **synovial joints in the hands and elbow**.
