Verified step by step guidance

Understand the concept of synovial joints: Synovial joints are the most movable type of joint in the body, characterized by a fluid-filled joint cavity. They are classified based on the type of movement they allow.

Review the types of synovial joints: Hinge joints allow movement in one plane (e.g., flexion and extension). Saddle joints allow biaxial movement (movement in two planes). Pivot joints allow rotational movement around a single axis.

Define multiaxial movement: Multiaxial movement refers to the ability of a joint to move in three planes—sagittal, frontal, and transverse. This includes movements such as flexion/extension, abduction/adduction, and rotation.

Identify the ball-and-socket joint: Ball-and-socket joints, such as the shoulder and hip joints, consist of a spherical head fitting into a cup-like socket. This structure allows for multiaxial movement, making them the most versatile type of synovial joint.

Conclude that the ball-and-socket joint is the correct answer: Based on its ability to permit movement in three planes, the ball-and-socket joint is the type of synovial joint that allows for multiaxial movement.
