25
What is the middle part of the sternum
Body
26
What is the notch on the superior border of the sternum
Jugular notch
27
The jugular notch is found where in the thoracic column
Disk space between T2 and T3
28
Where is the sternal angle located
At the junction of manubrium and sternal body
29
The sternal angle corresponds to what thoracic column
Disk space between T4 and T5
30
Where does the xiphoid process correspond in the thoracic column
T10
31
What determines whether a particular rib is true or false
Anterior articulations
32
What are false ribs
8-12
33
What structures form costovertebral joints
Heads of ribs with thoracic bodies
34
Costal tubercles articulate with
Transverse processes of thoracic vertebrae
35
What part of the sternum articulates with the anterior ends of the first pair of ribs to form the first sternocostal joints
Manubrium
36
The anterior end of a rib is located how many inches below the level of the head
3 to 5 inches
37
The patient should be rotated into an oblique position for the PA sternum for what reason
To prevent superimposition of the sternum with the vertebral column
38
Why is anterior oblique preferred rather than posterior oblique
To reduce object-to-image-receptor distance of the sternum
39
What level should the top of the IR be for a sternum
1.5 above the jugular notch
40
SID for a lateral sternum
72 inches
41
SID for PA sternum
40 inches
42
How should the patients arms be for a lateral sternum
Behind the patients back
43
Breathing technique for a lateral sternum
Stop breathing after inspiration
44
Patients who have experienced some trauma should be examined in what position
Dorsal decubitus
45
Where should the top pf the IR be for a PA upper rib
1.5 in above shoulders
46
Breathing technique for Upper ribs
Stop breathing on inspiration
47
Why should the patients shoulders be rotated forward in PA ribs
Move scapulae laterally away from ribs
48
Breathing technique for upper ribs
Stop breathing after inspiration, depresses diaphragm
49
Breathing technique for lower ribs
Stop breathing after expiration, elevates diaphragm
50
What ribs should be demonstrated on upper ribs
First ten
51
The lower edge of the collimated field for lower ribs should be
At illiac crests
52
Central ray for all ribs is
Perpendicular
53
What pair of ribs should be demonstrated on lower ribs
Lower 5
54
AP oblique projections demonstrate posterior or anterior ribs better
posterior
55
Which ribs should be placed closest to the IR
The affected side
56
How many degrees should the patient be rotated
45 degrees
57
The bone classification for the sternum is
Flat
58
Smallest part of the sternum
Xiphoid process
59
What part of the sternum does the first pair of ribs articulate
Lateral border of the manubrium
60
RIbs that have no anterior attachments
Floating ribs
61
What position would best demonstrate the anterior sixth rib on the left side
RAO
62
What position best demonstrates the anterior fifth rib on the right side
LAO
63
What articulation is formed in part with the head of a rib
Costovertebral
64
WHat structures do heads of ribs articulate with
Demifacets of thoracic vertebrae
65
What articulation involves the tubercle of a rib
Costotransverse
66
How much should the patient be rotated for RAO sternum
15-20 degrees
67
The floating ribs attach only to the
Thoracic vertebrae
68
A typical rib has

72
Between the ribs (1–10) and the costal cartilage
Costochondral
73
Between the costal cartilage and the sternum
Sternocostal
74
Between the costal cartilages
Interchondral
75
Between the manubrium and the body of the sternum
Manubriosternal
76
Between the xiphoid process and the body of the sternum
Xiphisternal
77
Located along the inferior anad internal border of each rib
Costal groove
78
Upper border of the IR for a lateral sternum
1.5 above the jugular notch
79
Central ray for lateral sternum
Mid-sternum on lateral border
80
Central ray for upper ribs
Perpendicular to IR
81
If the projection is PA what ribs are more demonstrated
