Spinal Vertebrae

Question 1

Verbal Arch

Answer 1

Anterior (Vertebral Body, endplates)
Posterior (Pedicals, laminae, Pars, Processes)
Create passage way for spinal cord

Question 2

Vertebral Body

Answer 2

(Soma/ centrum)

Cylindrical shaped structure

Question 3

Endplate

Answer 3

On superior and inferior of vertebral body
Attach to vertebral body and outer layer of disk
Two layers
-inner bony layer
-outer cartilaginous layer, attaches to lamella of disk
Acts as growth plate early in life
-allows nutrition to be transferred from cancellous bone to intervertebral disk

Question 4

Laminae

Answer 4

Thin plate of cortical bone that span Pericles and form posterior spinal canal
-protect posterior side of vertebral foramen

Question 5

Vertebral Foramen

Answer 5

Area between anterior and posterior vertebral arches where spinal cord runs down

Question 6

Pars Interacrticularis

Answer 6

Area between articulations processes and pedicle

Question 7

Pedicle

Answer 7

Column of cortical bone with cancellous center that joins posterior and anterior column of spine
-used for posterior screws

Question 8

Spinous Process

Answer 8

Middle of Laminae, projects inferior

• attachments for muscles and ligaments
• most posterior point of the spine

Question 9

Transverse Process

Answer 9

Extend laterally from junction of pedicle and laminae (2 of them)
-attachment points, acts as lever

Question 10

Articular process

Answer 10

Each spinal level has four, two superior and two inferior except for thoracic spine
-form a facet and zygapophyseal joint

Question 11

Intervertebral Foramina

Answer 11

Notches on adjacent vertebrae that create a lateral circular opening for nerve roots and blood vessels
-can impinge if discs deteriorate or facet joints hypertrophy
