10

What names ID ligaments that attach the dura mater to the vertebral body or pedicle?

Hofmann ligaments, (also megingeovertebral, anterior dural, Trolard's ligament)

11

Hofmann ligaments are IDed in which regions along the vertebral column?

Dura mater to segments above

13

What is the highest level known to demonstrate Hofmann ligaments?

C6

14

What is the proposed function of the cervical - upper thoracic Hofmann ligaments?

Resist causal movement of the dural sac; resist gravitational forces on the dura and cord

What is the proposed function to the lumbar Hofmann ligaments?

Resist cranial moment of the dural sac during flexion

17

What is the proposed function of the proximal root sleeve ligament?

Resist displacement of the peripheral never system in the intervertebral Foramen

Which is the greatest diameter of the enteral for mane of a typical lumbars?

Transverse

19

How does the size of the vertebral Foramen differ along the spine?

Cervicals have the greatest size, lumbars next, thoracics are smallest

22

What is the name of the elevation near the origin of the lumbar TVP?

Accessory porcess

23

A styloid process occurs with what frequency and as a result of what condition?
