What tissues and processes are responsible for growth and development?

Absolutely all tissues are capable of growing. That is, from birth in humans and any animal, the amount of epithelial, muscle, nervous and connective tissue increases. This is due to the active division of cells in a particular tissue. But we only grow up to a certain age, not until the end of life. Cell division for the growth of the body is possible only thanks to the growth hormone (somatropin). At a certain period, the active production of the hormone stops and cell division occurs more slowly. They divide to maintain normal bodily functions.
