Part A Drag the labels onto the diagram to identify the structures and regions of the thoracic cage. ANSWER: Thoracic vertebrae Jugular notch Clavicular notch Manubrium Sternal angle Body True ribs Sternum Xiphisternal joint Xiphoid process False ribs Floating ribs Costal cartilage Answer Requested Exercise 9 Review Sheet Reading Question 1 Part A Craniosynostosis is a condition in which one or more of the fontanelles are replaced with bone prematurely. Which of the following is not a possible consequence of this condition? ANSWER: When one or more fontanelles is closed prematurely, bone growth along the lateral aspects of the head can affect the small bones of the inner ear and result in deafness. When one or more fontanelles is closed prematurely, asymmetric growth of cranial bones can result in abnormal or asymmetric facial features. When one or more fontanelles is closed prematurely, the bones of the skull may not grow fast enough to accommodate the growing brain, resulting in increased intracranial pressure. When one or more fontanelles is closed prematurely, the bones of the skull cannot grow properly in all directions, resulting in an abnormal head shape. Correct Exercise 9 Review Sheet Reading Question 2 Part A Which of the following is not a reason we become shorter as we age? ANSWER: As a person ages, vertebral bodies lose bone mass (osteoporosis) resulting in smaller vertebrae that stack closer together. As a person ages, the intervertebral discs become thinner and the vertebrae will be stacked closer together, resulting in shorter stature. As a person ages, scoliosis may develop resulting in an abnormal spinal curvature and shorter stature. As a person ages, the ligaments connecting vertebrae together are weakened, resulting in a more pronounced kyphosis. This posterior curvature of the spine lowers the skull, making you shorter. Correct Scoliosis most often results during rapid growth spurts in childhood or adolescence and generally does not change much in middle age. Exercise 9 Review Sheet Reading Question 3 Part A Why might the xiphoid process be missing from the sternum in a set of human remains? ANSWER: The remains are from an adult younger than 40 years of age, and the hyaline cartilage does not preserve as well as bone. Because the xiphoid process shrinks with age Because the xiphoid process may be broken off if the individual had been given CPR Because the xiphoid process is small and does not articulate with any other bones Correct
