An example of controlled growth in humans is the development of fingers in specific locations. Hormones, especially those involved in development and growth, play a role in regulating the precise positioning and formation of fingers during embryonic and childhood growth.
Give an example of controlled growth in the human body and explain how hormones contribute to this regulation.

An example of controlled growth in the human body is the regulation of bone length during puberty. Growth hormone (GH), released by the pituitary gland, stimulates the growth plates in long bones. GH triggers the production of insulin-like growth factor 1 (IGF-1) in the liver, which, in turn, promotes cell division and elongation in the growth plates. This orchestrated hormonal cascade regulates the lengthening of bones, ensuring proportional growth. The tight control of hormones in response to developmental stages exemplifies the precision and coordination required for controlled growth in specific areas of the human body.
