It is crucial for glucose uptake and amino acid storage, influencing energy and protein metabolism across the body. Conditions like sarcopenia and cachexia result from muscle loss due to aging, diseases, and metabolic shifts, leading to negative health and economic consequences.

It highlights the importance of telomeres, which are protective noncoding DNA sequences at chromosome ends, in maintaining chromosome integrity and preventing fusion.

It also mentions that certain chromosomes may show preferential segregation while others distribute randomly, indicating variability in this process across different cell types.

Cardiac muscle, involuntary and reliant on oxygen, pumps blood, while smooth muscle regulates various functions without direct neuronal control. Skeletal muscle enables voluntary movement with specialized fibers. Muscle contractions are powered by ATP and facilitated by the sliding-filament model, with fibers classified as Type I or Type II.
