Imagine that you are part of a research team that specializes in diagnosing disorders associated with malfunctioning cellular structures. Medical doctors consult your group to help diagnose particularly difficult cases. You have been presented with the following data: Patient History: o Seven year-old boy o Fatigue o Muscle weakness o Low endurance o Loss of coordination o Progressive difficulty walkin Physical Examination o Muscle loss & deformity o Awkward gait o Difficulty breathing Laboratory Results o Cells have abnormal shape o Cell division is abnormal o Impaired intracellular movement of material. Explain which structures may be involved. Use the patient history data to support your conclusions.

Stress

Stress is defined as the feeling of being overwhelmed or unable to cope with emotional or mental pressure. Any event or action that makes a person annoyed, furious, or nervous can trigger it. Chemical changes in the body caused by stress can cause blood pressure, blood sugar levels, and heart rate to rise.
