Vertebral column

Question 1

Bear body weight, anchors muscles and ligaments, protects the spinal cord

Answer 1

Functions of the spine

Question 2

Each vertebra separated by

Answer 2

Intervertebral disk made of cartilage

Question 3

Basic component of vertebrae, a hole through which the spinal cord passes

Answer 3

Vertebral foramen

Question 4

Basic component of all vertebrae, main weight bearing portion composed of spongy bone

Answer 4

Vertebral body/centrum

Question 5

Basic component of all vertebrae, part of vertebrae that encloses the spinal cord posteriorly. Whole posterior latter half of vertebrae

Answer 5

Vertebral arch

Question 6

Basic component of all vertebrae, attach arch to the vertebral body, sides of centrum

Answer 6

Pedicle

Question 7

Basic component of all vertebrae, flat part of arch that attaches Pedicle to spinous process

Answer 7

Lamina

Question 8

Attached to Pedicle, tail end, very point of arch. Basic component of all vertebrae

Answer 8

Lamina

Question 9

Basic component of all vertebrae, lateral ridges that attaches muscles to the spine

Answer 9

Transverse process

Question 10

Points of articulation with other vertebrae, on top of bone with two ovular, smooth ridges. Inferior and superior, can be anterior or posterior

Answer 10

Articular facets

Question 11

Made of the body and two halves of vertebral arch, fuses together when more mature

Answer 11

Growth

Question 12

C1-C7, smallest and thickest bodies. Lots of mobility in the neck. Has transverse foramina and the spinous process is often horizontal and split in half

Answer 12

Cervical vertebrae

Question 13

Two small holes lateral to the body in cervical vertebrae

Answer 13

Transverse formina

Question 14

Split in half, cervical spinous processes are this

Answer 14

Bifurcated

Question 15

C1, lies between the cranium and the axis. Superior articular facets are long and concave, articulate with skull. No vertebral body or spinous process. Oval, huge foramen for the brain stem

Answer 15

Atlas

Question 16

C2, lacks vertebral body but has projecting process (odontoid process), allows for rotation of head

Answer 16

Axis

Question 17

Superiorly projecting knob in the axis that allows for rotation of the head

Answer 17

Odontoid process

Question 18

Intermediate in size between cervical and lumbar, triangular to circular shaped. Transverse processes are prominent lateral projections, no transverse formina, circular vertebral foramen. Giraffe

Answer 18

Thoracic vertebrae

Question 19

Smooth ocular surfaces where bones articulate with ribs, one on each side of the body, one on anterior surface of transverse process

Answer 19

Rib facets

Question 20

T2-T9, articulate with rib above and below

Answer 20

Demi-facets

Question 21

Points of articulation, smooth surface facing posteriorly

Answer 21

Superior articular facets

Question 22

Points of articulation, smooth surface facing anteriorly

Answer 22

Inferior articular facets

Question 23

No transverse rib facet, inferior articular facets assume lumbar pattern (most face anterior and posterior pattern, inferior of this one sets lateral medial)

Answer 23

T12

Question 24

Largest of all vertebrae, lack rib facets and transverse formina. Arches are small relative to bodies, spinous processes are hatchet shaped. Transverse processes are small, thin, and lack articular surfaces. Superior articular facets are perpendicular to the body. Moose

Answer 24

Lumbar vertebrae
