140) Todd is 13 and lives in an urban apartment. He spends most of his time watching TV and eating “junk” food. One afternoon, during recess, he falls on the playground and breaks his leg. Although he appears to be healthy, his leg takes longer to heal than expected. What might be the cause of the longer healing time?
Answer: Assuming that there is no other disease process involved, Todd’s problem is probably related to his poor diet. Good nutrition is important for promoting the healing process. Insufficient quantities of protein, vitamin C, vitamin A, and vitamin D would cause the normal healing process to occur at a much slower rate. Todd’s inactivity may also contribute to his slower rate of healing.
Learning Outcome: 6-7
Bloom’s Taxonomy: Application
141) An elderly patient has a broken femur that is healing very slowly. A young resident suggests using a device that will create an electrical field in the area of the fracture to help speed the healing process. Why might this possibly help?
Answer: Osteoblasts are attracted to electrical fields produced by bone crystals when they are stressed. This is one of the reasons that trabeculae of bones are organized along stress lines. If the same type of electrical field could be duplicated at the site of the fracture, osteoblasts may be stimulated to migrate to the area and increase the rate of bone production and thus healing of the fracture.
Learning Outcome: 6-7
Bloom’s Taxonomy: Application
142) Would you expect to see changes in blood levels of the hormones calcitonin and PTH as a result of vitamin D3 deficiency? Explain.
Answer: A person deficient in vitamin D3 would not be able to absorb calcium effectively from the digestive tract, leading to a shortage of calcium in the blood. To maintain homeostasis, the decrease in blood calcium would trigger the release of PTH. The PTH, in turn, would stimulate osteoclasts to release enough calcium from the bone to maintain proper calcium levels in the blood. Levels of calcitonin would decrease, because release of this hormone is triggered by high blood calcium levels.
Learning Outcome: 6-8
Bloom’s Taxonomy: Application
143) What is osteopenia? Name and define two forms of osteopenia.
Answer: Osteopenia is a general term for reduced bone mass. Osteoporosis and osteomalacia are forms. Osteoporosis is a condition of reduced bone density, bone weakness, and pain resulting from the loss of mineral from bone with advancing age. Osteomalacia is bone weakness caused by insufficient calcium deposits. It is known as rickets in the young.

Essay Questions
142) Frank gets into a brawl at a sports event and receives a broken nose. After the nose heals, he starts to have sinus headaches and discomfort in the area of his maxillae. What is probably the cause of Frank’s discomfort?
Answer: Frank probably has a deviated septum as the result of his broken nose. In a deviated septum the cartilaginous portion of the septum is bent where it joins the bone. This condition often blocks the drainage of one or more sinuses with resulting sinus headaches, infections, and sinusitis.

143) Sasha has a chronic sinus infection that she has treated herself. She develops a dangerous infection of the brain. Explain to her how this happened.
Answer: The paranasal sinuses in the frontal bone are only a few millimeters of bone away from the cranial cavity. Chronic infection has permitted the bone to be eroded and penetrated, introducing bacteria into the brain case.

Bloom’s Taxonomy: Application
144) What role do the fontanels play in infant development?
Answer: These fibrous connective tissue structures fill in between the bones of the cranium in a newborn infant. As the brain grows, the skull bones can move apart and allow for brain growth without interfering with nervous system development and function. If they are prematurely ossified, brain development is restricted, leading to skull deformity and mental retardation. This condition is called craniostenosis.

145) Joe is 40 years old and 30 pounds overweight. Like many middle-aged men, Joe carries most of this extra weight in his abdomen and jokes with his friends about his “beer gut.” During an annual physical, Joe’s physician advises him that his spine is developing an abnormal curvature. Why is the curvature of Joe’s spine changing, and what is this condition called?
Answer: The curvature of the spine is changing as a result of the heavy abdomen pulling on the anterior cavity. This extra weight causes abnormal spinal curvature to compensate for balance. The condition is called lordosis because its effects are prevalent in the lumbar region.
Learning Outcome: 7-6
Bloom’s Taxonomy: Application
146) Why are ruptured intervertebral discs more common in lumbar vertebrae and dislocations and fractures more common in cervical vertebrae?
Answer: The lumbar vertebrae have massive bodies and carry a lot of weight; these factors contribute to the rupturing of an intervertebral disc. The cervical vertebrae are more delicate and have small bodies; these factors increase the possibility of dislocations and fractures in the cervical vertebrae.

147) Billy is injured during a high school football game. His chest is badly bruised and he is experiencing difficulty in breathing. What might the problem be?
Answer: Billy has probably broken one or more of his ribs. Movement of the ribs changes the size of the thoracic cavity, which is an important part of breathing. When the ribs are broken, breathing can become difficult (labored) because of pain when the ribs are moved.

148) The structural features and skeletal components of the sternum make it a part of the axial skeleton, which is important in a variety of clinical situations. If you were teaching this information to prospective health care professionals, what clinical applications would you cite?
Answer: Because it is accessible, the body of the sternum is often sampled for red bone marrow. The xiphoid process is useful landmark in CPR; this part of the sternum is easily broken, because its only attachment is superior, to the sternum. A broken xiphoid process can cause injury to nearby organs.
