The Nervous System. The vegetative nervous system regulates the rate of metabolism, muscular action and the body temperature

Part II

The vegetative nervous system regulates the rate of metabolism, muscular action and the body temperature. It consists of two parts: the sympathetic system and the parasympathetic system. The sympathetic system is formed by the nerves regulating the activity of the heart muscle and the glands and conveying sensations from the internal organs to the cerebrum.

Cold stimulates the sympathetic nerves and they cause white muscle to contract. Heart has the opposite effect. Mammals and birds have the system highly developed whereas the cold-blooded animals, fish, frogs, etc. have no sympathetic system.

In many organs the activity of the sympathetic system is regulated by the parasympathetic nerves. For example, the sympathetic nerve increases the rate of the heart beat and the Vagus¹ (parasympathetic nerve) reduces it thus keeping the rate correct for the needs of the animal.

¹ Vagus – вагус, блуждающий нерв (парасимпатический нерв)
