Parasympathikus, parasympathisch/en

The parasympathetic nervous system (skin nerve: vagus nerve, 10th brain nerve) is one of the two important nerve structures of the vegetative nervous system.

It is also known as the "resting nerve" because it is mainly active during the regenerative phases and during digestion. It provides peace, relaxation and protection. Its centers are in the brain stem, upper spinal cord and sacral marrow. The carrier substance is acetylcholine. The main nerve is the predominantly cholinerge Nervus vagus, which supplies the organs of the thoracic and abdominal cavity with many branches.

Kleinere parasympathische Anteile weisen auch andere Hirnnerven auf. Die Wirkung des P. ist funktionell zumeist der des Sympathikus entgegengesetzt und dient vor allem der Ernährung, Energieersparnis und Erholung (trophotrope Wirkung).

New findings show that the vagus nerve (also) provides information from the bellybrain to the (head) brain.
