Question #1 To distinguish between muscular dystrophy and myasthenia gravis, clinicians examine muscle strength, fatigue patterns, and conduct specific tests. Muscular dystrophy is a genetic disorder characterized by progressive muscle degeneration, with elevated serum creatine kinase levels, and muscle biopsy showing fiber degeneration. Myasthenia gravis is an autoimmune disorder where antibodies attack acetylcholine receptors at the neuromuscular junction, leading to fluctuating muscle weakness that worsens with activity and improves with rest; antibody tests and electromyography assist diagnosis (Liscic et al., 2010). In muscular dystrophy, the deficiency involves structural proteins like dystrophin impairing muscle integrity, while in myasthenia gravis, the problem is a deficiency or blockade of acetylcholine receptor function. Muscles involved include proximal limb muscles and ocular muscles in both conditions, though distal muscles are less affected in early stages. The involved muscles show weakness and atrophy, while unaffected muscles remain relatively normal. Question #2 Problems at the neuromuscular junction in myasthenia gravis pose a significant threat to respiratory homeostasis. The disease affects the muscles responsible for breathing, notably the diaphragm and intercostal muscles (Skeans et al., 2022). Weakness here can impair ventilation, leading to respiratory failure in severe cases. As the neuromuscular junction's efficiency diminishes, the capacity to generate the necessary muscle contractions for effective breathing decreases, risking hypoxia and hypercapnia. Therefore, individuals with severe myasthenia gravis require close monitoring and sometimes mechanical ventilation. The compromised neuromuscular transmission not only impacts voluntary movements but also essential involuntary functions like respiration, emphasizing its threat to respiratory homeostasis. Question #3 One main function of muscles in the body is to produce movement. Skeletal muscles facilitate voluntary movements like walking, lifting, and speech by contracting and pulling on bones. Different types of muscles are needed because each muscle type fulfills specific roles; skeletal muscles are voluntary and
