- spinous tubercles between C2 and C7 inclusive

3

What are the specific bony attaching sites on the vertebra for the ligamentum nuchae?

the spinous tubercle or its homolog

4

What are the layers of the ligamentum nuchae?

superficial and deep layers

5

What is the name given to the superficial layer of the ligamentum nuchae?

the funicular layer or part

6

What is the name given to the deep layer of the ligamentum nuchae?

the lamellar layer or part

7

What are the attachment sites for the superficial layer of the ligamentum nuchae?

- external occipital protuberance

9

What is the status of the deep layer of the ligamentum nuchae in African-Americans?

it is typically a single layer reflecting the non-bifid spinous process condition

10

What is the status of the deep layer of the ligamentum nuchae in Caucasians?

it is paired where bifid spinous processes are present

11

What is the histological makeup of the ligamentum nuchae in quadrupeds?

it is a yellow elastic ligament

12

What is the histological makeup of the human ligamentum nuchae?

it is a yellow elastic ligament, but has more collagen fibers than in quadrupeds
