3 VISCERAL MOTORIC NEURON
DEFINISI Bagian dari SST Fungsi motorik Nervi craniales Nervi spinales Otot polos, otot jantung, glandula VISCERAL MOTORIC NEURON VISCERAL EFFECTOR

4 AUTONOMIC PATHWAY Memiliki 2 serabut neuron Preganglionik
SSP  ganglion Postganglionik Ganglion  efektor

5 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

6 TRUNCUS SYMPATHICUS

7 ILUSTRASI SIMPATIK pada keadaan stres akut Fight or flight
Stres akut teratasi ~ parasimpatik Terjadi efek sebaliknya

8 QUESTION ???? Simpatik >< parasimpatik Homeostasis

9 CRANIOSACRAL DIVISION
PARASYMPATHETIC DIVISION CRANIOSACRAL DIVISION Neuron preganglionik Medulla oblongata Mesencephalon Vertebrae sacrales Nn. craniales III, VII, IX, X Preganglionik ~ panjang Postganglionik ~ pendek

10 Nervi craniales

11 1 preganglionik bersinaps dg > 1 postganglionik
KLINIS: sebaran respon parasimpatis terbatas Umumnya organ menerima simpatik dan parasimpatik Beberapa organ  HANYA SIMPATIK saja

12

13 Fungsi otonom

14 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
