Flashcards in Lab 15- Vertebral Column and Thoracic Cage(test 2) Deck (27):
1

Cervical vertebrae

7
-C1 is atlas
-C2 is axis
-C7 is vertebra prominens

2

throacic vertebrae

12

3

lumbar vertebrae

5

4

sacrum

5 fused vertebrae
-superior articular process: superior projection with a facet articulation site
-anterior sacral foramen: passageway for blood vessels and nerves
-posterior sacral foramen: passageway for blood vessels and nerves
-sacral promontory: anterior border of S1; important landmark for obstetricians
-sacral canal: portion of vertebral canal
-median sacral crest: area of fused spinous processes
-sacral hiatus: inferior opening of vertebral canal

5

coccyx

formed by 3 to 5 fused vertebrae

6

intervertebral discs

fibrocartilage

7

vertebral canal

contains the spinal cord

8

cervical curavture

curve of the cervical vertrbrae

9

thoracic curvature

curve of the thoracic vertebrae

10

lumbar curvature

curve of the lumbar vertebrae

11

sacral (pelvic) curvature

curve of the pelvis and sacrum

12

intervertebral foramina

passageway for spinal nerves

13

vertebral foramen

location of the spinal cord

14

body

largest part of the vertebrae; main support portion

15

pedicles

form lateral area of vertebral foramen

16

laminae

thin plates forming posterior area of vertebral foramen

17

spinous processes

posterior projection

18

transverse processes

lateral projections

19

facets

articulating surfaces

20

superior articular process

superior projections

21

inferior articular processes

inferior projections

22

inferior vertebral notch

space for nerve passage

23

transverse foramina

only present in cervical vertebrae; passageway for blood vessels

24

dens (odontoid process) of axis

superior process of C2 and is a pivot location at atlas

25

rib

head-expanded end near thoracic vertebra
tubercle-projection near thoracic vertebra
neck-narrow region between head and tubercle
shaft-main portion
anterior (sternal) end-costal cartilage location
facets-articulation surfaces
true ribs-1-7
false ribs-8-12
*floating ribs-10-12

26

costal cartilage

hyaline cartilage

27

sternum

jugular (suprasternal) notch- superior concave border of manubrium
clavicular notch- articulation site of clavicle
manubrium- superior part
sternal angle- junction of manubrium and body at level of second rib
body- largest, middle part
xiphoid process- inferior part; remains cartilaginous until adulthood
