Spine (Bones, joints, and Characteristics)

Question 1

Body of vertebrae

Answer 1

Weight bearing surface

Question 2

Vertebral arch

Answer 2

Composed of the pedicles and the laminae

Question 3

Vertebral foramen

Answer 3

Space created by the body and vertebral arch

Question 4

Vertebral canal

Answer 4

Contains the spinal cord and its coverings; it is created by successive vertebral foramina

Question 5

Spinous process

Answer 5

Extension posterior from the meeting of the lamina

Question 6

Transverse process

Answer 6

Lateral projection originating at the junction of the lamina and pedicle

Question 7

Superior articular process

Answer 7

2 superior projections from the superior portion of the lamina to form the synovial joints (ZPJ) with the vertebra directly above

Question 8

Inferior articular process

Answer 8

2 inferior projections from thr inferior portion of the lamina to form the synovial joints (ZPJ) with the vertebra directly below

Question 9

Inferior vertebral notch

Answer 9

Indentation of the inferior edge of the pedicle

Question 10

Superior vertebral notch

Answer 10

Indentation of the superior edge of the pedicle

Question 11

Intervertebral foramen

Answer 11

Space created by the superior vertebral notch of the vertebra adjacent to the inferior vertebral notch of the above vertebra. Spinal nerves are transmitted through these foramen.

Question 12

Characteristic of Cervical spinous processes

Answer 12

Bifid

Question 13

Foramina transversaria

Answer 13

Vertebral artery passes through the foramina in the transverse processes

Question 14

Characteristics of the C1 vertebra

Answer 14

Atlas
No spinous process
No body
Articulates with the occipital condyles
Rotates on the axis

Question 15

Characteristics of the C2 vertebra

Answer 15

Axis

Dens - projects superior, for the rotation of the atlas

Question 16

Characteristics of the thoracic vertebra

Answer 16

Long, slender, inferior projecting spinous process

Articular facets for the articulation with ribs

Question 17

Characteristics of the lumbar vertebra

Answer 17

Heavy bodies for weight bearing

Stout transverse processes

5 fused vertebrae

4 sacral foramina that translate nerves S1-4

Question 19

Characteristics of coccyx

Answer 19

4 fused bones

The facet joints are what kind of joints?

Answer 22

Synovial joints

Question 23

What structure limits extension?

Answer 23

Anterior longitudinal ligament

Question 24

What structure does not limit movement, but rather prevents the discs from moving into the dura?

Answer 24

Posterior longitudinal ligament

Question 25

What structure reinforces the medial capsule of the Zygapophyseal Joint? ( V shaped)

Answer 25

Ligamentum flavum

Question 26
