What is the primary characteristic of synovial joints?

1. They are immovable

2. They allow free movement

3. They have limited movement

4. They are solely found in the spine

The correct answer is: They allow free movement

The primary characteristic of synovial joints is that they allow free movement. Synovial joints are highly mobile and are designed to facilitate a wide range of motion, making them the most flexible type of joint in the human body. They are characterized by the presence of a synovial cavity, which is filled with synovial fluid that lubricates the joint and enables smooth movement between the articulating bones. These joints can be found in various locations throughout the body, including the knees, elbows, shoulders, and hips, among others. This functional design is vital for activities requiring significant movement, such as running, jumping, and lifting. The mobility granted by synovial joints is essential in supporting essential daily functions and activities.
