IS - SISTEMA NERVIŻA SIMPATETIKA JEW INVOLUNTARJA

Din is-sistema tikkonsisti f'żewġ bagolli prinċipali jew kordi ta 'ganglia (ċentri tan-nervituri), li jestendu mill-bażi tal-moħħ sal-kokċaj, u li jinsabu parzjalment fuq il-ġnub tal-lemin u tax-xellug u parzjalment quddiem il-kolonna tas-sinsla; u, barra minn hekk, ta 'tliet plexus tan-nervituri kbar u ħafna ganglia iżgħar fil-kavitajiet tal-ġisem; u ta 'bosta fibri tan-nervituri li jestendu minn dawn l-istrutturi. Iż-żewġ wajers jikkonverġu hawn fuq f’gangljun żgħir fil-moħħ, u taħt fil-ganglion tal-koċċiċjali quddiem il-kokkuċ.

Fig. VI-C

In Fig. VI-B, to the left of the spinal column, is indicated one of the two cords of the involuntary nervous system. From it are seen to extend widespread ramifications of nerve fibers, which forma the plexuses that are spread like spider webs over the digestive and the other organs in the body cavities; in the solar plexus they are joined by the vagus nerve of the voluntary system.

Il-Fig. VI-C huwa disinn li jindika ż-żewġ kordi gangljoniċi tas-sistema involontarja, li jikkonverġu taħt; jinżel bejniethom huwa l-korda spinali, li jispiċċa ħdejn il-coccyx. Fuq il-ġnub huma indikati l-kliewi, miżjuda bl-adrenali.
