Which of the following permits movement of articulating bones around two axes?

Options

A. Hinge joint
B. Ball & socket joint
C. Sutures
D. Ellipsoid joint

Answer

To answer the question, "Which of the following permits movement of articulating bones around two axes?" we need to analyze the types of joints and their movements.

### Step-by-Step Solution:

1. **Understanding Joint Types**:
- The question asks about joints that allow movement around two axes. Common types of joints include ellipsoid joints, hinge joints, ball-and-socket joints, and sutures.

2. **Ellipsoid Joints**:
- Ellipsoid joints, also known as condyloid joints, allow movement in two planes: flexion and extension (back and forth movement) as well as abduction and adduction (side to side movement).
- Examples include the joints in the palms of the hands and the soles of the feet.

3. **Hinge Joints**:
- Hinge joints, like those found in the elbow and knee, allow movement primarily in one plane (flexion and extension). They do not permit movement around two axes.

4. **Ball-and-Socket Joints**:
- Ball-and-socket joints, such as those in the shoulder and hip, allow for a wide range of movement, including rotation and movement in multiple planes. However, they are not limited to just two axes.

5. **Sutures**:
- Sutures are fixed joints found in the skull that do not allow any movement. They serve to connect the bones of the skull securely.

6. **Conclusion**:
- Based on the analysis, the joint that permits movement of articulating bones around two axes is the **ellipsoid joint**.

### Final Answer:
The joint that permits movement of articulating bones around two axes is the **ellipsoid joint**.
