Where Is The Nuchal Ligament On A Horse?
dorsal neck region.
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. The nuchal ligament is characteristically yellow.
Where does the nuchal ligament start and end?
Structure. The
Where is the ligamentum nuchae located?
neck
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. It is a superior and posterior extension of the supraspinous ligament.
Where does nuchal ligament start?
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.
Where does the nuchal ligament end?
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.
How far does the nuchal ligament go?
The nuchal ligament (NL) extends from the external occipital protuberance and median nuchal line to the spinous process of the 7th cervical vertebrae.
What muscles attach to nuchal ligament?
Provides an attachment for Trapezius and Splenius capitis.
What is the function of the nuchal lines?
The superior nuchal line provides an attachment surface on its inferomedial side for the semispinalis capitis muscle, and on its inferolateral side for the obliquus capitis superior.
Can you feel the ligamentum nuchae?
You should be able to easily feel the
How common is nuchal cord injury?
After birth, the baby’s umbilical cord is cut and clamped, leaving a stump that heals to form the baby’s belly button. Research suggests that nuchal cord incidents are common and occur in up to 25% of pregnancies.
How do you release nuchal cord?
There’s no way to prevent or treat a nuchal cord. Nothing can be done about it until delivery. Health professionals check for a cord around the neck of every single baby born, and usually it’s as simple as gently slipping it off so that it doesn’t tighten around the baby’s neck once the baby has started to breathe.
What are the 3 more important ligaments of the spine?
The three major ligaments of the spine are the ligamentum flavum, anterior longitudinal ligament (ALL), and posterior longitudinal ligament (PLL) (Fig. 7). The ALL and PLL are continuous bands that run from the top to the bottom of the spinal column along the vertebral bodies.
What causes nuchal ligament calcification?
Calcification of the
What causes ossification of the nuchal ligament?
Trauma or overload in cervical spine may cause injury to ligamentum nuchae and chronic accumulation of the injury may cause cervical instability2,18,20,21). In general, cervical instability leads to osteophyte formation, disc degeneration in cervical spine. And injury to ligamentum nuchae may cause OLN.
What are the four nuchal lines?
The nuchal lines are four curved lines on the external surface of the occipital bone: The upper, often faintly marked, is named the highest nuchal line, and to it the galea aponeurotica is attached.

How can you tell the difference between T1 and C7?
C7 and T1 vertebrae.
C7, also called vertebra prominens, is the last cervical vertebra. T1 is the first thoracic vertebra. C7 has a longer spinous process (bony protrusion), which can be felt in the back of the neck. T1’s spinous process projects at a more downward angle and may not be as prominent.
How do you palpate C7?
Palpate the spine to determine the spinous processes of C7 and mark this point. C7 can be identified by palpating the base of the occiput down into the deep hollow where the next bony prominence felt will be C2, then C3-5 are closely packed and the spine of C6 is very prominent.
What animals have a nuchal ligament?
It keeps an animal’s head steady when it runs. Horses, dogs, cheetahs, and other good runners have such a ligament. Traces of a nuchal ridge can be found in skulls millions of years old, so the next step was to check the fossils of early humans at the renowned Peabody Museum.
What is the line on top of the skull called?
Cranial
Where is inferior nuchal line?
Running from the middle of the median nuchal line, across either half of the nuchal plane is the inferior nuchal line. The inferior nuchal line and the area below it receive the insertions of the Recti capitis posteriores major and minor.
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.
