What Role Does Genetic Information Play in Histology?

Histology, the study of tissues, is deeply intertwined with genetic information. Each tissue type in the body is composed of cells that have specific functions determined by their genetic information. For example, the genetic information within muscle cells directs the production of proteins like actin and myosin, which are essential for muscle contraction. Similarly, neurons have genetic instructions that enable the synthesis of neurotransmitters necessary for signal transmission.
