Which joints are described as freely movable?

• A. Synovial joints
• B. Fibrous joints
• C. Cartilaginous joints
• D. Ball-and-socket joints

Answer: (A)

Freely movable joints are those that have a synovial cavity and supporting structures (joint capsule, synovial fluid, ligaments, and articular cartilage) that allow a wide range of motion. This describes synovial joints. They include subtypes like ball-and-socket joints, which illustrate this high degree of mobility (shoulder and hip). In contrast, fibrous joints are typically immovable or only slightly movable (like skull sutures), and cartilaginous joints are limited in movement (such as intervertebral joints or the pubic symphysis). So the category that fits the description of freely movable is synovial joints.
