Here's why:
* GH influences almost every cell in the body. It promotes growth and development in a wide variety of tissues, including:
* Bone and cartilage
* Muscle
* Liver
* Adipose tissue
* Internal organs
* Skin
* GH plays a role in various metabolic processes:
* Protein synthesis
* Carbohydrate metabolism
* Fat metabolism
* Cell division and differentiation
While other hormones like insulin and thyroid hormone also affect many organs, they are more focused on specific metabolic functions. GH's influence on growth and development across so many tissues makes it the hormone with the broadest target range.
