CO OZNACZA SŁOWO PREGANGLIONIC
Włókna nerwowe preganglionowe
W autonomicznym układzie nerwowym włókna z CNS do zwoju są znane jako włókna preganglionowe. Wszystkie włókna preganglionowe, czy to w strefie sympatycznej, czy w układzie współczulnym, są cholinergiczne i niemyelinowane lub mielinizowane. Sympatyczne włókna preganglionowe są krótsze niż włókna prekaplastyczne, ponieważ zespoły współczulne są często bliższe rdzeniu kręgowym niż pasożytnicze węzły chłonne. Inną ważną różnicą między dwoma systemami ANS jest rozbieżność. Podczas podziału parasympatycznego występuje współczynnik rozbieżności rzędu 1: 4, w podziale współczulnym może występować rozbieżność do 1:20. Wynika to z liczby synaps uformowanych przez włókna preganglionowe z neuronami ganglionowymi.
