Which class of Lever is being described if you are standing on tiptoes and if: • The Fulcrum is at the metatarsal and phalanges, which is at one end of this lever on the anterior side of the body. • The Load is your body weight which is in the middle of this lever. •The Effort is exerted by the gastrocnemius and soleus muscles at the calcaneal (Achilles') tendon on the other side of this lever on the posterior side of the body. First class Lever O None of the above, because this action is not possible in the body and such a lever does not exist. Second class Lever Third class Lever

A normally active 21-year-old college student is 5'8" tall and weighs 160 pounds. While working out at the fitness center, he student drops a 15 pound weight on his foot. After seeing the doctor at the student clinic, X-rays show three fractured bones in the foot. The doctor decides to put the student in a cast for four weeks and on crutches for the first two weeks. The doctor cautions the student to be careful. When the student returns in four weeks to get the cast removed, the doctor notices that the student has gained 10 pounds and attributes the weight gain to the student's decreased activity level while wearing the cast. Is it realistic that someone could gain 10 pounds in a 1-month time frame? Why or why not? Calculate the student's BMI before and after the accident - what is the difference in BMI between pre and post injury? Be sure to show calculations. Discuss concerns the doctor might have with the weight gain.

Which of the following statements best differentiates the difference between a synovial and fibrous joint? Synovial joints are fluid-filled, fibrous joints are not. A fibrous joint is triaxial, a synovial joint is biaxiall. A fibrous joint allows for a greater range-of-motion than a synovial joint. Fibrous joints are filled with fluid, synovial joints are not.
