AUTONOMIC PATHWAYMemiliki 2 serabut neuronPreganglionikSSP ganglionPostganglionikGanglion efektor

SYMPATHETIC DIVISIONMenunjukkan asal neuron preganglionik bersinaps di ganglion dengan neuron postganglionik1 preganglionik bersinaps dengan >>>> postganglionikKLINIS: jalur simpatik akan merangsang banyak organ sekaligusTHORACOLUMBAL DIVISIONTRUNCUS SYMPATHICUS

ILUSTRASI SIMPATIK pada keadaan stres akutFight or flightStres akut teratasi ~ parasimpatikTerjadi efek sebaliknyaQUESTION ????Simpatik >< parasimpatikHomeostasis

Neuron preganglionik Medulla oblongataMesencephalonVertebrae sacralesNn. craniales III, VII, IX, XPreganglionik ~ panjangPostganglionik ~ pendek
