Short- Answer (10 points): Answer all of the Questions:
16. You are working as a doctor and a young girl about sixteen years old comes in complaining of back
pains. You notice that she has a distorted post and she claims that her mother suffered from a similar

your patient. Is she suffering from Lordosis, Kyphosis and Scoliosis? Explain your reasoning.
17. Bernice, a 75-year-old woman stumbled slightly while walking, then felt a terrible pain in her left
hip. At the hospital X-rays revealed that the hip was broken. Also, the compact and spongy bone
throughout her spine was very thin. What was her probable condition? Use evidence to support your
reasoning.
18. The X-ray image of the arm of an accident victim reveals a faint line curving around and down the
shaft. What kind of fracture might this indicate? Explain your reasoning.
19.If you were working as a nutritionist, what would a daily meal plan look like that you might devise
