Flashcards in General organization of a vertebra Deck (36):
1

What are the three basic osseus parts of a vertebra?

the vertebral body, vertebral arch and the apophyseal region

2

what is formed by the vertebral body and vertebral arch?

the vertebral foramen

3

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

cervical - rectangular; thoracic - triangular; lumbar is reniform

4

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

5

what are the names of the openings found around the margins of the vertebral body?

the basivertebral venous foramen

6

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

the pedicle

7

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

the lamina

8

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

the lamina - pedicle junction

9

what is the name given to the feature located at the upper and lower surfaces of the pedicle?

the superior vertebral notch or incisures; the inferior vertebral notch or 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

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

what classification of bone will para articular processes represent?

accessory bone

14

what is the name given to the overlap of laminae seen on xray?

shingling

15

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

cervical -articular pillar; thoracic and lumbar - pars interarticularis

16

what is the name given to the junction of the vertebral arch spinous process on lateral xray?

the spinolaminar junction

17

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

the apophyseal region

18

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

19

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

cervical - anterolateral; thoracic - postero lateral; lumbar - lateral

20

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

the costal element

21

what is the name given to the rounded elevation at the end of the transverse apophysis or transverse process?

the transverse tubercle

22

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

23

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

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 fron 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

what names are given to the part of the vertebra which supports the front of the zygapophysis?

the superior articular apophysis, the superior articular process, or the prezygapophysis

28

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

29

what will form the posterior boundary of a typical IVF?

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

30

What will form the superior boundary of a typical IVF?

the inferior vertebral notch or inferior vertebral incisure

31

what will form the inferior boundary of a typical IVF?

the superior vertebral notch or incisure

32

what will form the anterior boundary of a typical IVF?

the vertebral body of the segment above, the vertebral body of the segment below, the intervertebral disc, and the 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 apophysis and the horizontal plane

34

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

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
