[[File:Gray303.png|thumb|Gray303.png]] '''Ligamenta flava''' (singular: '''ligamentum flavum''') are a series of ligaments that connect the laminae of adjacent vertebrae from the axis (C2) to the first segment of the sacrum (S1). These ligaments are part of the [[vertebral column]] and play a crucial role in maintaining the stability and flexibility of the spine.

==Anatomy==
The ligamenta flava are composed of elastic connective tissue, which gives them a yellowish color, hence the name "flava" (Latin for "yellow"). They are situated on the posterior side of the vertebral canal and extend from the posterior surface of the lamina of the vertebra below to the anterior surface of the lamina of the vertebra above.

==Function==
The primary function of the ligamenta flava is to preserve the upright posture and assist in the return to the normal position after flexion of the spine. They also help to protect the [[spinal cord]] and [[spinal nerves]] by forming a part of the posterior wall of the vertebral canal.

==Clinical Significance==
Degeneration or hypertrophy of the ligamenta flava can lead to conditions such as [[spinal stenosis]], where the spinal canal narrows and compresses the spinal cord and nerves. This can result in symptoms such as pain, numbness, and weakness in the limbs. Surgical procedures, such as [[laminectomy]], may be performed to relieve this compression.
