C)The tubercle of a typical rib attaches to the inferior articular facet of the corresponding vertebrae.
D)The head of a typical rib articulates with the bodies of two vertebrae.
E)The costal groove is associated with the intercostal vessels and nerve.
2.Rib fractures:
A)are more likely to occur in children than adults.
B)are most likely to occur at the junction of the rib and its corresponding vertebrae.
C)most often occur in the 1st rib.
D)in the lower ribs may be associated with tearing of the diaphragm.

3.The sternal angle:
A)indicates the location of the joint between the costal cartilage of the 2nd rib and the
sternum.
B)occurs where the 1st rib attaches to the sternum.
C)is the least likely part of the sternum to fracture in the elderly.
D)occurs at the sternoclavicular joint.
E)is a depression in the body of the sternum. 4.Which of the following is incorrect pertaining to the sternum?
A)It may be surgically split in the median plane to gain access to the thoracic cavity.
B)It may be used for a bone marrow biopsy.
C)It may have a perforation (sternal foramen) that is sometimes the site of a pleural herniation, which is a life-threatening situation.
D)In violent thoracic trauma (e.g., automobile accident), comminuted fractures are not uncommon.
E)Its xiphoid process may partially ossify, producing a pronounced lump.
5.The superior thoracic aperture:
A)is bounded posteriorly by the axis.
B)is bounded anterolaterally by the clavicle.
C)is bounded anteriorly by the trachea.
D)is a larger opening than the inferior thoracic aperture.
E)is, anatomically, the thoracic inlet.
6.Which of the following associations is incorrect?
A)rib separation—separation of a rib and its costal cartilage
B)rib dislocation (slipping rib syndrome)—separation of a costal cartilage from the sternum
C)joints between costal cartilage of ribs 2–7 and sternum—symphyses
D)rib movements—mostly around a transverse axis passing through the head, neck, and tubercle
E)rib movements—increase A-P diameter of the thorax during respiration 7.Which of the following associations is incorrect?
A)serratus posterior superior—potentially can elevate superior ribs
B)scalenus anterior—stabilizes 1st rib enabling more effective rib elevation during forced inspiration
C)external intercostal muscles—attach to the sternum
D)intercostal vessels and nerve—travel between internal and innermost intercostals muscles
E)diaphragm—primary muscle of respiration
8.The endothoracic fascia:
A)is continuous with the clavipectoral fascia.
B)provides a surgical cleavage plane between the thoracic wall and the costal parietal pleura.
C)attaches to the suspensory ligaments of the breast.
D)contains the intercostal muscles.
E)may become fibrous and thus interfere with normal respiratory movements.
9.A patient complains to you of pain in a limited strip on one side of his chest and back. Upon examination you notice that the skin associated with the T3 dermatome of that side is red with vesicular eruptions. Which of the following is your most reasonable conclusion about your patient's illness?
A)He has syphilis.
B)He has shingles (herpes zoster).
C)He has localized dermatitis.

artery?

C)overproduction of milk.
D)menopause.
E)bacterial infection of the lactiferous ducts (ductus lactiferi).
12.Lymphatic drainage of the breast:
A)is principally to the ipsilateral parasternal lymph nodes.
