How the fingers knows when to stop growing longer?

In: 1

Answer 1

The bones in our fingers stop growing when we reach adulthood. The reason our fingers know when to stop growing is because of a hormone called growth hormone. This hormone is produced by the pituitary gland, which is located at the base of the brain. Growth hormone signals the body to start growing and to stop growing.
