Which type of joint is characterized as movable?

The correct answer is diarthrosis, which refers to a type of joint that is fully movable. Diarthrosis joints are characterized by a synovial cavity that allows for a wide range of motion. This type includes familiar joints such as the knees, elbows, shoulders, and hips, enabling various movements like flexion, extension, rotation, and more. The mobility is facilitated by structures such as synovial fluid, cartilage, ligaments, and the joint capsule, which work together to ensure smooth movement and reduce friction.

Understanding the characteristics of diarthrosis joints highlights their essential role in the human body’s mobility, distinguishing them from other joint types like fibrous and cartilaginous joints, which have limited or no movement.
