Q

Connective tissue which forms ligaments except Ligamentum Flavum

A

Dense fibrous CT

17
Q

Connective tissue of ligamentum flavum

A

Elastic fibers

18
Q

Encompasses almost the entir anterior surface of the vertebral column, attaches the base of the skull to the sacral curvature
Limits overextension

A

Anterior Longitudinal Ligament

19
Q

Very strong ligament

The ONLY ligament that limits extension

A

Anterior longitudinal ligament

20
Q

Ligament which weakly resists hyperflexion of the vertebral column
Helps prevent herniation of the nucleus pulposus to prevent pressure on spinal cord

A

Posterior longitudinal ligament

21
Q

Accessory ligament of intervertebral joints found in the posterior wall of vertebral column; yellow in collor because of the elastic fibers; attaches one lamina to the other; thickest in the lumbar region

A

Ligamentum flavum

22
Q

Resist separation of vertebral lamina by limiting abrupt flexion of vertebral column; preserve normal curvatures of the column; assist with straightening of column after flexing

A

Ligamentum flavum

23
Q

Limits lateral flexion

A

Intertransverese ligament

24
Q

Ligament which resists hyperflexion and too much rotation/twisting

A

Supraspinous ligament

25
Q

Ligament that runs from skull to C7

A

Ligamentum nuchae

26
Q

Innvervation of splenius muscles

A

Posterior rami of spinal nerves

27
Q

Chief extensors of the vertebral column

A

Errector Spinae
