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
