Which of the following pairs, is correctly matched ?

Options

A. Cartilaginous joint - skull bones
B. Hinge joint - between vertabrae
C. Fibrous joint - between phalanges
D. Gliding joint - between zygapophyses

Answer

To determine which of the given pairs is correctly matched, we will analyze each option one by one:

### Step 1: Analyze the first option - Cartilaginous joints and skull bones
- **Explanation**: Cartilaginous joints are joints where the bones are connected entirely by cartilage. However, skull bones are actually connected by fibrous joints, which are immovable.
- **Conclusion**: This option is incorrect.

### Step 2: Analyze the second option - Hinge joint and vertebrae
- **Explanation**: Hinge joints are a type of synovial joint that allow movement along one axis, typically found in places like the elbow and knee. The vertebrae are connected by cartilaginous joints (intervertebral discs), not hinge joints.
- **Conclusion**: This option is also incorrect.

### Step 3: Analyze the third option - Fibrous joints and phalanges
- **Explanation**: Fibrous joints are found between skull bones, and phalanges (finger bones) are connected by hinge joints, allowing for bending and straightening. Therefore, this pairing is incorrect.
- **Conclusion**: This option is incorrect as well.

### Step 4: Analyze the fourth option - Gliding joints and zygapophysis
- **Explanation**: Gliding joints, also known as planar joints, allow bones to glide over one another in various directions. The zygapophysis refers to the joints between the vertebrae, which are indeed gliding joints.
- **Conclusion**: This option is correct.

### Final Answer:
The correctly matched pair is **Gliding joints and zygapophysis**.
