AUTONOMIC NERVOUS SYSTEM
FUNCTION:
fylogenetically the oldest part of NS, control smooth muscles,
glands, heart
FUNCTIONAL DIVISIONS:
Parasympaticus – anabolic reactions (store the energy)
Sympaticus – catabolic function (release the energy)
Enteric system
MORPOLOGICAL DIVISIONS:
Central
Peripheral
