The accumulation of 'lactic acid' in the muscles results in:
Correct answer: A. Extreme fatigue
- A. Extreme fatigue
- B. Muscle contraction
- C. Paralysis
- D. Convulsion
Explanation
Extreme fatigue, or severe tiredness, is an overwhelming sense of exhaustion that isn't relieved by rest. It can be caused by various factors, including physical exertion, stress, sleep disorders, medical conditions (like anemia or thyroid issues), or mental health disorders (like depression). It may impact daily activities and overall quality of life.

About Muscle Contraction
Muscle contraction is explained by the sliding filament model, in which myosin heads pull actin filaments within sarcomeres using ATP. The topic covers calcium, troponin, tropomyosin, the neuromuscular junction and relaxation, with attention to how filament length stays almost constant while the sarcomere shortens.
