Nuchal fascia

Nuchal fascia is a deep layer of fascia located in the posterior part of the neck. It is a fibrous membrane that covers the muscles and structures of the neck, providing support and allowing for movement.

Anatomy

The nuchal fascia is divided into two layers: the superficial layer and the deep layer. The superficial layer is attached to the occipital bone and the spinous processes of the cervical vertebrae. The deep layer, also known as the prevertebral fascia, covers the deep muscles of the neck.

The nuchal fascia is continuous with the ligamentum nuchae, a fibrous band that extends from the external occipital protuberance of the skull to the seventh cervical vertebra.

Function

The nuchal fascia serves several important functions. It provides a smooth surface for the movement of the neck muscles, reducing friction between these muscles and the surrounding structures. It also helps to contain and protect the muscles and structures of the neck, including the spinal cord and vertebral column.

Clinical significance

Injuries or disorders of the nuchal fascia can lead to neck pain and reduced mobility. Conditions such as whiplash or torticollis can cause inflammation and tightness in the nuchal fascia, leading to discomfort and difficulty moving the neck.
