21

Easily identified by transverse foramina found in their transverse processes; allows passage of vertebral arteries and veins

22

Large, teardrop-shaped vertebral foramen; lacks a vertebral body; articulate with occipital bone and C2 respectively

c1 or atlas

Prominent superior tooth-shaped projection called dens (odontoid process) protrudes from body; articulates with atlas at atlantoaxial joint; Allows for rotational movement of head at neck

axis

24

sacrum

25

hornlike projections found on each side of superior aspect of coccyx

coccygeal cornu

26

remnants of transverse processes; on posterior surface

transverse regions

27

fibrocartilage pad found between bodies of adjacent vertebrae; absorbs shock and binds vertebral column together

intervertebral disks

28

a part of the intervertebral disk; soft jelly-like substance; shock absorber

nucleus pulposus

29

a part of the intervertebral disk; outer ring of fibro cartialedge that contains nucleus pulposes

anulus fibrosus

30

consists of sternum, 12 pairs of ribs, and thoracic vertebrae, which form protective peripheral boundary of thoracic cavity

thoracic cage

31

superiormost segment that has a suprasternal notch with a clavicular notch on either side, articulates with clavicles of pectoral girdle; part of thoracic cage

manubrium

32

large middle segment of sternum

body

33

inferior segment oc the sternum; protrusion that provides an attachment site for certain abdominal muscles

xyphoid process

34

how do ribs attach to the thoracic vertebra?

Each rib attaches to a thoracic vertebra posteriorly

35

how can you tell if it's a true rib or not?

-true rib is connected to cartiledge then the sternum
-false rib is connected to cartiledge and more cartiledge

36

what consists of clavicle and scapula

pectoral girdle; appendicular region

37

what end of the clavicle articulates laterally with acromion process of scapula

Acromial

38

hook-shaped projection on anterior surface of the scapula

coracoid process

39

inferior to coracoid process; provides an attachment site for subscapularis muscle; dished out region

subscapular region

40

shallow indentation found on lateral surface of the scapula; articulates with humerus in shoulder joint

glenoid cavity

41

posterior ridge of bone; crosses from medial to lateral along superior scapula and terminates as acromion at acromioclavicular joint (AC)
