The ellipsoidal joint is found in

Options

A. hip
B. knee
C. shoulder
D. radius and scaphoid of hand

Answer

To determine where the ellipsoidal joint is found, we can analyze the options given in the question step by step.

### Step-by-Step Solution:

1. **Understanding Ellipsoidal Joints**:
- Ellipsoidal joints, also known as condyloid joints, allow movement in two planes. They facilitate flexion, extension, abduction, and adduction.

2. **Evaluating the Options**:
- **Option 1: Hip Joint**:
- The hip joint is a ball-and-socket joint, which allows for a wide range of motion. Therefore, this option is incorrect.
- **Option 2: Knee Joint**:
- The knee joint primarily functions as a hinge joint (tibiofemoral joint), allowing flexion and extension. Thus, this option is also incorrect.
- **Option 3: Shoulder Joint**:
- The shoulder joint is another example of a ball-and-socket joint, which allows for extensive movement in multiple directions. Hence, this option is incorrect as well.
- **Option 4: Radius and Scaphoid of Hand**:
- The joint between the radius and the scaphoid bone in the wrist is an ellipsoidal joint. This joint allows for movement in two planes, making this option the correct answer.

3. **Conclusion**:
- The ellipsoidal joint is found in the radius and scaphoid of the hand.

### Final Answer:
The ellipsoidal joint is found in the radius and scaphoid of the hand (Option 4).
