The nervous system exerts its effect almost instantly, since nerve signals propagate through the processes of nerve cells at a very high speed. The endocrine system develops its effect on the body more slowly. The synthesis of hormone molecules, the release of these molecules from the cells of the glands, as well as the delivery of blood to the target organs – all these processes are time-consuming. But the duration of this effect, in contrast to the action of nerve signals, can be significant.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
