Where does the ligamentum nuchae attach?
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 a ligamentum nuchae?
The ligamentum nuchae is a large median ligament composed of tendons and fascia located between the posterior muscles of the neck. It covers the spines of C1 to C6 vertebrae.
What muscles attach to 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 does ligamentum nuchae limit?
This ligament runs up and down the spine (vertical or longitudinal). The Posterior Longitudinal Ligament runs up and down behind (posterior) the spine and inside the spinal canal….Primary Spinal Ligaments Include:
| Ligament | Spinal Region | Limits… |
|---|---|---|
| Ligamentum Nuchae | Cervical | Flexion |
Why is the ligamentum nuchae important?
It is thick and strong, limiting hyperflexion of the neck. In quadriped animals, it is very strong and functions in keeping the neck and head of the animal up. The ligamentum nuchae consists of the dorsal raphe and medial septal parts. The dorsal raphe attaches to muscles while the medial septum does not.

What are the symptoms of a torn ligament?
The signs of a torn ligament can vary depending on the severity of the injury, as can the treatments for such injuries. Pain is, of course, one of the most common signs of a torn ligament, though pain can be accompanied by bruising, swelling, immobility, and even a popping sound when the ligament tears.
What are the grades of ligament tears?
If you have a sprain, your doctor may mention its “grade”: Grade I is stretching of the ligament or a very mild tear, with little or no instability at the joint. Grade II is a more serious but still incomplete tear, with some looseness in the joint. Grade III is a completely torn or ruptured ligament.
What is the difference between a ligament and a tendon?
Following are the key differences between tendons and the ligaments: Tendon connects muscles to bone, and are present at the end of skeletal muscles and are made of white fibrous connective tissue, whereas ligaments connect one bone to another bone, so found in joints and are made of yellow fibrous connective tissues.
What is posterior longitudinal ossification?
Ossification of the posterior longitudinal ligament (OPLL) is a condition in which a flexible structure known as the posterior longitudinal ligament becomes thicker and less flexible. The posterior longitudinal ligament connects and stabilizes the bones of the spinal column.
