Ing somatic nervous system ing manibala ba lang mikakametung (coordinated) deng kimut ning katawan, at bang tanggap stimulus manibat king kilwal. Ing autonomic nervous system ing dake ning sistema nerviosa kareng kimut a e sasaryan, nung nu malilyari ing pamag-mantining pangkilub (internal maintenance).


Mapipitna ya ing autonomic nervous system king [[sympathetic nervous system|sympathetic division]] ampong [[parasympathetic nervous system|parasympathetic division]]. Makibat ya ing sympathetic nervous system king peligru o king stress. Ya ing sangkan nung bakit sisikan ya kabug ing pusu at mitatas ing prisyun ning metung a tau, bukud kareng aliwang pamanaliwa king pamipulayi (physiological changes) ning katawan, pati na ing panamdaman nang pamikarug o pangasabik a panamdaman ning tau. Samantala, apapansinan ta ne man ing parasympathetic nervous system neng makapaynawa ya’t taimik kabilyan (relaxed) tamu. Iti ing manibala king pamagkitid (constriction) ning pupil, ing pangabagal king kabug ning pusu, ing pangaliwalas da reng uyat a daralanan ning daya, ampo ing “pamanyalangi” o pamagsinyal (stimulation) kareng sistema king pamaglaso pamangan ampong pamani (digestive and genitourinary systems).
