Q

What classification of bone will para-articular processes represent?

A

accessory bone

1
Q

What ligament will attach to the lamina?

A

the ligamentum flavum

2
Q

What is the name given to abnormal bone at the attachment site of the ligamentum flavum?

A

para-articular process

3
Q

What is the name given to the overlap of laminae seen on X-ray?

A

Shingling

4
Q

What is the name given to the lamina - pedicle junction at each region of the spine?

A

cervical - articular pillar; thoracic and lumbar - pars interarticularis

5
Q

What is the name given to the junction of the vertebral arch - spinous process on lateral X-ray?

A

the spinolaminar junction

6
Q

What is the generic orientations of the transverse process or transverse apophysis at each region of the spine?

A

cervical - anterolateral; thoracic - posterolateral; lumbar - lateral

7
Q

All non-rib-bearing vertebra of the spine retain what equivalent feature?

A

the costal element

8
Q

What will cause the transverse process/transverse apophysis to alter its initial direction in the cervical region

A

cervical spinal nerves are pulled forward to form the cervical and brachial nerve plexuses thus remodeling the transverse process to accommodate their new position

9
Q

What will cause the transverse process/transverse apophysis to alter its initial direction in the thoracic region?

A

the growth of the lungs remodel the shape of the ribs which in turn push the transverse process backward

10
Q

What is the name given to the joint formed between articular facets of a vertebral couple?

A

the zygapophysis

11
Q

What will form the posterior boundary of a typical intervertebral foramen?

A

the inferior articular process/post-zygapophysis, the capsular ligament, and the ligamentum flavum

12
Q

What will form the superior boundary of a typical intervertebral foramen?

A

the inferior vertebral notch or inferior vertebral incisure

13
Q

What will form the inferior boundary of a typical intervertebral foramen?

A

the superior vertebral notch or superior vertebral incisure

14
Q

What will form the anterior boundary of a typical intervertebral foramen?

A

the vertebral body of the segment above, the vertebral body of the segment below, the intervertebral disc and the posterior longitudinal ligament

15
Q

What is the method of calculating the angle of the spinous process/spinous apophysis?

A

calculate the angle formed between the undersurface of the spinous process/spinous apophysis and the horizontal plane

16
Q

What is the name given to the normal overlap of spinous processes or spinous apophyses as seen on X-ray?

A

imbrication

17
Q

What is the name given to the rounded elevation at the tip of the spinous process/spinous apophysis?

A

the spinous tubercle

19
Q

What is the orientation of the spinous process/spinous apophysis at each region of the spine?

A

Cervical- slight angle inferiorly
thoracic - noticeable angle inferiorly
lumbar - no inferior angle

20
Q

What is the general shape of the vertebral body at each region of the spine?

A

cervical- rectangular; thoracic- triangular; lumbar-reniform

21
Q

What is the name given tot he compact bone at the superior and inferior surfaces of the vertebral body?

A

superior epiphyseal rim, inferior epiphyseal rim

22
Q

What is the name given to the intermediate part of the vertebral arch where the transverse process and articular processes attach?

A

the lamina - pedicle junction

23
Q

What is the generic orientation of the pedicle at each region of the spine?

A

cervical - posterolater
thoracic - posterior, slight lateral
lumbar- posterior
