What is the nuchal ligament in a horse?
The nuchal ligament, a large elastic structure in the dorsal cervical region, helps support the head and neck in the horse. During locomotion, the caudal funicular and cranial lamellar regions make the largest contribution to elastic strain energy storage.
What is a nuchal ligament?
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. In quadriped animals, it is very strong and functions in keeping the neck and head of the animal up.
How is the nuchal ligament formed?
Structurally, the nuchal ligament is formed with the association of both elastin proteins as well as type III collagen (45%). The collagen fibrils share a consistent size as well as helical pattern which gives the ligament its tensile strength. The elastin on the other hand is a protein that allows for flexibility.
What are the nuchal ligament attachment points?
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 nuchal ligament in animals?
The nuchal ligament is a fibrous membrane, which, in the neck, represents the supraspinal ligaments of the upper part of the spine. As it is required for running, not all animals have a nuchal ligament.
What is a nuchal anatomy?
The nuchal region, otherwise known as the posterior region of the neck or the posterior cervical region, is the area at the back of the neck situated deep to the trapezius muscle. It contains the spinal cord, cervical vertebrae and all the associated muscles.
How long do neck ligaments take to heal?
With proper treatment and rest, most patients will recover from a neck strain or sprain within four to six weeks. If the strain or sprain is severe, it can take three months or more to fully recover.
How long does it take for ligaments in the neck to heal?
For mild to moderate neck sprains, the ligaments will gradually heal over time. This typically takes 4 to 6 weeks. Severe neck sprains can take significantly longer to heal and fully recover.
Where is the nuchal ligament on a horse?
dorsal neck
The nuchal ligament is a large elastic structure in the dorsal neck region that supports the horse’s head and the neck. It consists of about 80% of elastin fibers and some of collagen fibers.
