1

What are the three basic osseous parts of a vertebra?

The vertebral body, vertebral arch, and the apophyseal regions

2

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

Cervical- Rectangular
Thoracic- Triangular
Lumbar- Reniform

3

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

Superior epiphyseal rim, inferior epiphyseal rim

4

What is the name given to the cartilage found at the superior and inferior surface of a developing vertebral body?

Superior epiphyseal plate, inferior epiphyseal plate

5

What are the names given to the openings found around the margins of the vertebral body?

Nutrient foramina or vascular foramina

6

What large opening is usually observed at the back of the vertebral body?

Basivertebral Venous Foramen

7

What is the name of the feature located at the upper and lower surfaces of the pedicle?

The superior vertebral notch or superior vertebral incisure
The inferior vertebral notch or inferior vertebral incisure

8

What is the name given to the anterior part of the vertebral arch?

The pedicle

9

All lamina are oriented in what direction?

Posterior and median

10

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

Shingling

11

What ligament will attach to the lamina?

The ligamentum Flavum

12

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

Para articular process

13

The classification of bone will para-articular processes represent?

Accessory bone

14

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

Cervical - articular pillar; thoracic and lumbar - pars interartiularis

15

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

The spinolaminar junction

16

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

The apophyseal regions

17

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

The transverse apophysis or transverse processes, articular apophysis or articular process; spinous apophysis or spinous process

18

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

Cervical- anterolateral
Thoracic- posterolateral
Lumbar- lateral

19

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

The costal element

20

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

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

21

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

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

22

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

The zygapophysis

23

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

The superior articular facet

24

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

The inferior articular facet

25

In the vertebral column, the part of the vertebra which lies anterior to to the zygapophysis is called the ___?

pre-zygapophysis

26

In the vertebral column, the part of the vertebra which lies posterior to the zygapophysis is called the ____?

Post-zygapophysis

27

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

The superior articular process or superior articular apophysis

28

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

The inferior articular process or inferior articular apophysis

29

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

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

30

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

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