Flashcards in Exam 1-General Organization of a Vertebra Deck (39):
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-trianglular; lumbar-reniform

3

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

superior epiphyeal rim, inferior epiphyseal rim

4

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

superior epiphyseal plate and 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 feature located at rhe upper and lower surfaces of the pedicle?

the superior vertbral 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

All lamina are orientated in waht direction?

posterior and median

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 X-ray

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 on lateral x-ray?

the spinolaminar junction

17

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

the apophyseal regions

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 orspinous process

19

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

cervical-anterolateral; thoracic-posterolateral; 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 cervicaland 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 will the articular process/articularapophysis support?

the articular facet

25

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

the zygapophysis

26

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

the superior articular facet

27

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

the inferior articular facet

28

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

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

29

What are the name 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

30

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

the superior articular preocces or superior articular apophysis

31

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

the inferior articular process or inferior articular apophysis

32

What will form the postertior 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

33

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

the inferior vertebral notch or inferior vertebral incisure

34

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

the superior vertebral notch or superior vertebral incisure

35

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, and posterior longitudinal ligament

36

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

37

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

imbrication

38

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

the spinous tubercle

39

The orientatiuon of the spinous process/spinous apophysis at each region of the spine?

cervical-slight angle inferiorly
thoracic-noticeable angle inferiorly
lumbar-no inferior angle
