What is the semicircular region of the bone attached to the back of the vertebral body called?

The vertebral arch

1

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

The pedicle

2

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

The lamina

3

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

4

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

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

5

What ligament will attach to the lamina?

The ligamentum flavum

6

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

Para-articular process

7

What classification of bone will para-articular processes represent?

Accessory bone

8

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

Shingling

9

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

Cervical- articular pillar; thoracic and lumbar - pars interarticularis

10

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

the spinaolaminar junction

11

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

the apophyseal regions

12

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

13

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

cervical- anterolateral; thoracic- posterolateral; lumbar- lateral

14

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

the costal element

15

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

the transverse tubercle

16

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
