Flashcards in Exam 1 - Organization of the Vertebra Deck (36):
1

What are the three basic osseous parts of a vertebra?

the vertebral body
vertebral arch
apophyseal regions

2

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

cervical - rectagular
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 of 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?

the basivertebral venous foramen

7

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

the pedicle

8

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

the lamina

9

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

the superior vertebral notch / superior vertebral incisure
the inferior vertebral notch / inferior vertebral incisure

10

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

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

11

All lamina are oriented in what direction?

posterior and median

12

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

shingling

13

What ligament will attach to the lamina?

the ligamentum flavum

14

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

para-articular process

15

What classification of bone will para-articular processes represent?

accessory bone

16

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

cervical - articular pillar
thoracic and lumbar - pars interarticularis

17

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

spinolaminar junction

18

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

the apophyseal regions

19

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

20

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

cervical - anterolateral
thoracic - posterolateral
lumbar - lateral

21

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

the costal element

22

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

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

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

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

24

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

the zygapophysis

25

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

the superior articular facet

26

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

the inferior articular facet

27

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

pre-zygapophysis

28

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

post-zygapophysis

29

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

the superior articular process / superior articular apophsis

30

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

the inferior articular process / inferior articular apophysis

31

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

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

32

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 intervertebral disc
posterior longitudinal ligament

33

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 apohysis and the horizontal plane

34

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

imbrication

35

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

the spinous tubercle

36

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
