Ligamentum nuchae

Ligamentum Nuchae

The Ligamentum Nuchae is a significant anatomical structure in the vertebrate skeletal system. It is a large, elastic ligament that extends from the external occipital protuberance on the back of the skull and the posterior border of the foramen magnum to the seventh cervical vertebra in the neck, also known as the vertebra prominens.

Structure

The Ligamentum Nuchae is a continuation of the supraspinous ligament and is composed of yellow elastic tissue. It is broad, thick, and somewhat triangular in shape, with its base attached to the skull and its apex fixed to the seventh cervical vertebra.

Function

The Ligamentum Nuchae serves several important functions in the body. It acts as a support for the muscles of the back and neck, allowing them to maintain the posture of the head. It also serves as a protective barrier, shielding the delicate spinal cord and nervous system from damage.

Clinical Significance

Injuries or conditions affecting the Ligamentum Nuchae can have serious implications for an individual's health. These can include whiplash, a common injury in car accidents, and ankylosing spondylitis, a type of arthritis that affects the spine.
