Cаse Study: (5 pts tоtаl) Jаsоn, a 25-year-оld college athlete, plays on his university’s soccer team. During a match, he suffered a severe fall, resulting in a tibial fracture (broken shinbone) in his right leg. Jason was immediately taken to the hospital, where he underwent surgery to insert a metal rod to stabilize the bone and aid in healing. After several weeks of rest, Jason begins physical therapy to rehabilitate his leg and regain strength. The physical therapist emphasizes that muscle atrophy (weakening of the muscles due to disuse) has occurred in Jason's quadriceps, hamstrings, and calf muscles while his leg was immobilized. Describe the process of healing after a bone fracture (the 4 steps) – (2) What cellular processes are involved in bone remodeling? (2 pts) Explain how muscle atrophy occurs and how it might affect Jason’s ability to walk and play soccer after his injury. What happens to muscle fibers when they are not used for extended periods?
