Understand the classification of joints based on their movement: Joints can be classified as synarthrotic (immovable), amphiarthrotic (slightly movable), or diarthrotic (freely movable).
Identify the characteristics of an amphiarthrotic joint: These joints allow for slight movement and are typically connected by cartilage.
Examine each option: The elbow and shoulder joints are examples of diarthrotic joints, which allow for free movement. Sutures of the skull are synarthrotic joints, which are immovable.
Consider the pubic symphysis: This joint is located between the left and right pubic bones and is connected by fibrocartilage, allowing for slight movement, especially during childbirth.
Conclude that the pubic symphysis is an example of an amphiarthrotic joint, as it fits the criteria of being slightly movable and connected by cartilage.
