Due to the accumulation of (a) Lactic acid in the muscles, a person feels tired. During intense physical activity, the body’s demand for energy increases. When oxygen supply to the muscles cannot keep pace with this demand, such as during vigorous exercise, the muscles switch to anaerobic metabolism.
During anaerobic metabolism, glucose is broken down into pyruvate, which is then converted into lactic acid when oxygen levels are low. The buildup of lactic acid in the muscles leads to a drop in pH, resulting in muscle fatigue, soreness, and a sensation of tiredness.
Although lactic acid was previously thought to cause muscle fatigue, recent research suggests that it may actually play a role in providing energy to muscles during strenuous activity. However, its accumulation can still contribute to the sensation of fatigue experienced during prolonged or intense exercise, making it a key factor in understanding muscle fatigue and performance.

The property of self-vibration, also known as automaticity, is found in the (a) Heart muscle. The heart possesses its intrinsic electrical conduction system, which initiates and coordinates rhythmic contractions without external stimulation. This unique property enables the heart to generate its rhythmic heartbeat, essential for pumping blood throughout the body and maintaining circulation.
Unlike skeletal muscles, which require external stimuli from nerves to contract, cardiac muscle cells can spontaneously depolarize and generate action potentials. This ability is crucial for the heart’s function as a pump, ensuring that it continues to beat even in the absence of neural input.
While other organs such as the kidney, liver, and intestine have muscle tissue, they do not possess the same inherent property of self-vibration or automaticity. Instead, their muscular activity is typically regulated by the autonomic nervous system or influenced by hormonal signals in response to physiological needs such as digestion, filtration, and detoxification.
The most powerful muscle of the human body is the Jaw. The jaw muscles, including the masseter and temporalis muscles, are exceptionally strong due to their daily function of chewing and biting.

The most powerful muscle of the human body is the Jaw. The jaw muscles, including the masseter and temporalis muscles, are exceptionally strong due to their daily function of chewing and biting. These muscles enable the crushing and grinding of food, exerting substantial force to break down tough or resistant substances.
The masseter muscle, located at the jaw’s side, is particularly robust and is often considered the strongest muscle in proportion to its size. It contracts with immense force during activities like chewing gum or tough foods, showcasing its power.
While other muscles like the gluteus maximus in the buttocks or the quadriceps in the thighs are also formidable in strength, the jaw muscles consistently demonstrate exceptional power due to their evolutionary importance in securing nourishment through mastication, which is crucial for survival and sustenance.
