VISCERAL MOTORIC NEURON DEFINISI Bagian dari SST Fungsi motorik Nervi craniales Nervi spinales Otot polos, otot jantung, glandula VISCERAL MOTORIC NEURON VISCERAL EFFECTOR
AUTONOMIC PATHWAY Memiliki 2 serabut neuron Preganglionik SSP ganglion Postganglionik Ganglion efektor
THORACOLUMBAL DIVISION SYMPATHETIC DIVISION THORACOLUMBAL DIVISION Menunjukkan asal neuron preganglionik bersinaps di ganglion dengan neuron postganglionik 1 preganglionik bersinaps dengan >>>> postganglionik KLINIS: jalur simpatik akan merangsang banyak organ sekaligus
TRUNCUS SYMPATHICUS
ILUSTRASI SIMPATIK pada keadaan stres akut Fight or flight Stres akut teratasi ~ parasimpatik Terjadi efek sebaliknya
QUESTION ???? Simpatik >< parasimpatik Homeostasis
CRANIOSACRAL DIVISION PARASYMPATHETIC DIVISION CRANIOSACRAL DIVISION Neuron preganglionik Medulla oblongata Mesencephalon Vertebrae sacrales Nn. craniales III, VII, IX, X Preganglionik ~ panjang Postganglionik ~ pendek
Nervi craniales
1 preganglionik bersinaps dg > 1 postganglionik KLINIS: sebaran respon parasimpatis terbatas Umumnya organ menerima simpatik dan parasimpatik Beberapa organ HANYA SIMPATIK saja
Fungsi otonom
NEUROTRANSMITTER Komunikasi sinaps Preganglionik Asetilkolin (ACh) ACh dari preganglionik didegradasi oleh kolinesterase di membran post sinaps Postganglionik Parasimpatik ACh Simpatik norepinephrin (NE) Inhibisi reuptake o/ membran presinaps
