Flashcards in Vertebral Column/Spinal Column (General Organization of a Vertebra) Deck (35):
1

What are the three basic osseous parts of a vertebra?

The vertebral body, vertebral arch, adn 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 larege opening is usually observed at the back of the vertebral body?

The basivertebral venous foramen

5

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

The pedicle

6

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

The lamina

7

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

The lamina-pedicle junction

8

What is the name given to 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

9

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

Cervical- posterolateral
Thoracic- posterior, slight lateral
Lumbar- posterior

10

What ligament will attach to the lamina?

The ligamentum flavum

11

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

Para-articular porocess

12

What classification of bone will para-articular processes represent?

Accessory bone

13

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

Shingling

14

What is the name give tot eh lamina-pedicle junction at each region of the spine?

Cervical-articular pillar; thoracic and lumbar-pars interarticularis

15

What is the name given to the junction of the vertebral arch-spinous process on 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 process; 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 is the name given to the rounded elevation at the end of the transverse apophysis or transverse process?

The transverse tubercle

21

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

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

22

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 backwards

23

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

The zygaphophysis

24

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

The superior articular facet

25

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

The inferior articular facet

26

What names are given to the part of the vertebra which support s the front of the zygapophysis?

The superior articular apophysis, the superior articular process, or the pre-zygapophysis

27

What names are given to the part of the vertebra which supports the back of the zygapophysis?

The inferior articular apophysis, the inferior articular process, or the post-zygapophysis

28

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

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

29

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

The inferior vertebral notch or inferior vertebral incisure

30

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

The superior vertebral notch or superior vertebral incisure

31

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

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

32

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

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

33

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

Imbrication

34

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

The spinous tubercle

35

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

Cervical- slight angle inferiorly
Thoracic- noticeable angle inferiorly
Lumbar- no inferior angle
