Ligamenta flava
Ligamenta Flava
Ligamenta flava (pronunciation: li-ga-men-ta fla-va) are a pair of ligaments found in the vertebral column. They are also known as the yellow ligaments due to their yellowish color.
Etymology
The term "ligamenta flava" is derived from the Latin words "ligamentum" meaning "band" or "tie", and "flavus" meaning "yellow". This is in reference to the yellowish color of the ligaments, which is due to the high concentration of elastic fibers.
Anatomy
The ligamenta flava are short, broad, elastic ligaments that connect the laminae of adjacent vertebrae, from the axis to the sacrum. They are thickest in the lumbar region and thinnest in the thoracic region. They help to preserve the upright posture, and to assist the vertebral column in resuming it after flexion.
Related Terms
