Plant turbulence and talk about it

Vegetative system dysfunction should be called autonomic nerve dysfunction. It is composed of sympathetic nerve and parasympathetic nerve, which mainly controls cardiac muscle, smooth muscle, visceral activity and gland secretion, is dominated and regulated by cerebral cortex and hypothalamus, and is not controlled by will, so it is called autonomic nerve. Under normal circumstances, sympathetic nerves and parasympathetic nerves with opposite functions are mutually balanced and restricted. In these two nervous systems, when one plays a positive role, the other plays a negative role, which is a good balance, coordination and control of physical activities. This is the function of autonomic nerve. If the balance of autonomic nervous system is broken, there will be various dysfunction.
