What are the facet joints?

• A. Curvatures along the spine responsible for flexibility
• B. Connections between vertebrae that allow for controlled movement and stability of the spine
• C. Spinal canals that protect nerve roots
• D. Muscles attached to the vertebrae for support

Answer: (B)

Facet joints, found in the spine, are crucial components that connect adjacent vertebrae. They facilitate controlled movement and provide stability to the spinal column. Each vertebra has a pair of facet joints, which are small synovial joints located at the posterior part of the spine. These joints allow for various movements, including flexion, extension, rotation, and lateral bending, while also limiting excessive motion that could lead to injury. This anatomy is designed to maintain the structural integrity of the spine while enabling a range of movements necessary for daily activities. Their role in preventing excessive movement helps to minimize the risk of injuries and degenerative conditions, which further highlights their importance in spinal function and health.
