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

,Ans: E
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

Ans: C
7. Which of the following associations is incorrect?

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.
Ans: B
