Which of the following is a cartilaginous joint?

Options

A. Gomphosis
B. Suture
C. Syndesmosis
D. Symphysis

Answer

To determine which of the following is a cartilaginous joint, we need to analyze each option provided:

1. **Gonfosis**: This is a type of fibrous joint that binds the teeth to their bony sockets. Since it is classified as a fibrous joint, it is not a cartilaginous joint.

2. **Suture**: Sutures are also fibrous joints found only in the skull (or cranium). They connect the bones of the skull together. Therefore, sutures are not cartilaginous joints.

3. **Syndesmosis**: This is another type of fibrous joint where two parallel bones are united. As it is a fibrous joint, it does not qualify as a cartilaginous joint.

4. **Symphysis**: This is a type of secondary cartilaginous joint. It is composed of fibrocartilage and allows for slight movement. Symphyses are found in the midline of the skeleton, such as the pubic symphysis.

Based on the analysis, the only cartilaginous joint among the options is **Symphysis**.

### Final Answer:
The cartilaginous joint is **Symphysis**.
