(B) Cardiac muscles do not get fatigued because they possess a high density of mitochondria,which provide a continuous supply of $ATP$ through aerobic respiration.Additionally,they have an abundant supply of myoglobin for oxygen storage and are connected by intercalated discs that allow for synchronized contraction.While they are involuntary,their resistance to fatigue is primarily due to their specialized metabolic adaptations rather than just their neural control.
