Facet joints, also known as zygapophyseal joints, are synovial joints located between the articular processes of two adjacent vertebrae, playing a crucial role in providing stability and flexibility to the spine. These joints are integral in allowing movements such as bending and twisting while also helping to protect the spinal cord by limiting excessive movement.

Zygapophyseal joints, also known as facet joints, are synovial joints located between the articular processes of adjacent vertebrae in the spine, playing a crucial role in providing stability and facilitating motion. These joints are essential in limiting excessive movement and protecting the spinal cord and nerves from injury.

zygapophyseal joints

Synovial joints are the most common and movable type of joint in the human body, characterized by a fluid-filled joint cavity that reduces friction and facilitates smooth movement. These joints are crucial for a wide range of motions and include structures such as the knee, hip, and shoulder joints.

synovial joints

Articular processes are projections on vertebrae that form joints with adjacent vertebrae, allowing for flexibility and movement of the spine. They play a critical role in maintaining the stability of the vertebral column while permitting a range of motions such as bending and twisting.
