2 NERVOUS SYSTEM – CENTRAL NERVOUS SYSTEM – PERIPHERAL NERVOUS SYSTEM PERIPHERAL NERVOUS SYSTEM SOMATIC NERVOUS SYSTEM AUTONOMIC NERVOUS SYSTEM SOMATIC NERVOUS SYSTEM MOTORIC NERVOUS SYSTEM SENSORIC NERVOUS SYSTEM AUTONOMIC NERVOUS SYSTEM PARASYMPATHIC SYMPATHIC

3 Bagian dari SST Fungsi motorik – Nervi craniales – Nervi spinales Otot polos, otot jantung, glandula

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

5 Menunjukkan asal neuron preganglionik  bersinaps di ganglion dengan neuron postganglionik 1 preganglionik bersinaps dengan >>>> postganglionik KLINIS: jalur simpatik akan merangsang banyak organ sekaligus

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

8 Simpatik >< parasimpatik Homeostasis

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

14 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

15 Use this chapter well into another subject as basic knowledge
