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

17
Q

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

A

spinolaminar junction

18
Q

What is the name given to the tubular bone growth regions of the vertebral arch?

A

the apophyseal regions

19
Q

What names may be given to each apophysis of the spine?

A

the transverse apophysis or transverse process
articular apophysis or articular process
spinous apophysis or spinous process

20
Q

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

A

cervical - anterolateral
thoracic - posterolateral
lumbar - lateral

21
Q

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

A

the costal element

22
Q

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

A

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

23
Q

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

A

the growth of the lungs remodel the shape of the ribs which in turn push the trasverse processes backwards

24
Q

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

A

the zygapophysis

25
Q

What is the name given to the bone surface at the front of a zygapophysis?

A

the superior articular facet

26
Q

What is the name given to the bone surface at the back of a zygapophysis?

A

the inferior articular facet

27
Q

In the vertebral couple, the part of the vertebra which lies anterior to the zygapophysis is called the…

A

pre-zygapophysis

28
Q

In the vertebral couple, the part of the vertebra which lies posterior to the zygapophysis is called the…

A

post-zygapophysis

29
Q

What is the name given to the part of the vertebra forming the pre-zygapophysis?

A

the superior articular process / superior articular apophsis

30
Q

What is the name given to the part of the vertebra forming the post-zygapophysis?

A

the inferior articular process / inferior articular apophysis

31
Q

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

A

the inferior articular process / post-zygapophysis
superior articular process / pre-zygapophysis
the capsular ligament
the ligamentum flavum

32
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
posterior longitudinal ligament

33
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 apohysis and the horizontal plane

34
Q

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

A

imbrication

35
Q

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

A

the spinous tubercle

36
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
