What kind of structures does a symphysis joint connect?

1. Structures joined by cartilage

2. Structures bound with metal implants

3. Structures freely moving in liquid

4. Structures closely held with elastic bands

The correct answer is: Structures joined by cartilage

A symphysis joint specifically connects structures through a type of cartilage known as fibrocartilage. This type of joint provides a small amount of movement, allowing for some flexibility while maintaining stability between the connected structures. The most common example of a symphysis joint in the human body is the pubic symphysis, which connects the two halves of the pelvis. The presence of cartilage in these joints allows for cushioning and shock absorption, crucial for activities that involve movement and stress on the bones, such as walking or running. This differentiates symphysis joints from other types of joints that may involve rigid structures, free movement in liquid, or elastic connections, none of which accurately describe the characteristics of a symphysis joint.
