Others, like neurons and cardiac muscle cells, are largely post-mitotic, meaning they do not divide frequently and must be repaired rather than replaced. This phenomenon, known as cellular differentiation, occurs during development as cells activate or silence specific gene sets.
Somatic Cell Functions in the Human Body
Furthermore, the accumulation of molecular damage within somatic cells over time is a primary driver of the aging process, contributing to the decline in physiological function observed in later life. Each of these cells, barring specific immune system exceptions, holds an identical copy of the organism's genome.
Somatic cells, conversely, are dedicated to the current organism's survival, growth, and maintenance. Evolutionary and Biological Significance.
Somatic Cell Functions in the Human Body
Somatic cells represent the vast majority of cellular material within a complex organism, forming the structural and functional foundation for every tissue and organ outside of the reproductive system. Unlike gametes, which are destined for genetic transmission to the next generation, these cells are diploid, meaning they contain two sets of chromosomes inherited from each parent.
