What muscle originates on the ligamentum nuchae?

The ligamentum nuchae is formed primarily from the aponeurotic attachments of the adjacent and subjacent musculature. From superficial to deep, these muscles are the trapezius; rhomboideus minor; splenius capitis; and the serratus posterior superior.

What is the origin of ligamentum nuchae?

It rises from the spinous process of C7 to the inion of the occipital bone, attaching all the posterior tips of the spinous processes in between. It is thick and strong, limiting hyperflexion of the neck.

What is the origin and insertion points of the nuchal ligament?

The nuchal ligament originates at the large dorsal process of C2 and inserts to the prominent dorsal spinous process of T1, continuing caudally with the supraspinous ligament.

What are the attachments of the nuchal ligament?

The nuchal ligament attaches to the spinous processes of the seven cervical vertebrae as it descends down the neck. At the base of the neck (at the 7th (last) cervical vertebra) the nuchal ligament then continues down the back of the spine as the supraspinous ligament.

What muscles attach to nuchal lines?

To it is attached, the splenius capitis muscle, the trapezius muscle, and the occipitalis. From the external occipital protuberance a ridge or crest, the external occipital crest also called the median nuchal line, often faintly marked, descends to the foramen magnum, and affords attachment to the nuchal ligament.

What attached to ligamentum nuchae?

Attachments. Extends from the external occipital protuberance on the skull and median nuchal line, to the spinous process of C7. The deep fibers of the ligament attach to the external occipital crest, the posterior tubercle of the atlas, and to the medial surface of the bifid processes of the other cervical vertebrae.

What is the ligamentum nuchae?

Here’s the nuchal ligament, also called the ligamentum nuchae. It’s a sheet of strong fibrous tissue that extends from the spinous process of the first thoracic vertebra, to the external occipital protuberance. The nuchal ligament limits forward flexion of the head and the cervical spine.

Where does trapezius muscle attach?

The muscle attaches to the medial third of superior nuchal line; external occipital protruberance, nuchal ligament, and spinous processes of C7 – T12 vertebrae.

What is the insertion of the trapezius muscle?

Origin Medial one-third of superior nuchal line, external occipital protuberance, spinous processes of vertebrae C7-T12, Nuchal ligament
Insertion posterior border of the lateral one-third of the clavicle, acromion process, and spine of scapula

What is the nuchal ligament made of?

We studied the anatomy of the nuchal ligament in five cadavers. Results: The nuchal ligament extends from the external occipital protuberance to the spinous process of the seventh cervical vertebra (C7). It is covered by layers of cervical fascia and the aponeurosis of the trapezius muscle.

Where does the nuchal ligament attach?
