WebbThere are different types of postganglionic neurons in the SNS and PNS branches of the autonomic nervous system. Postganglionic neurons of the PNS branch are classified as cholinergic, meaning that acetylcholine (ACh) is released, whereas postganglionic neurons of the SNS are classifed as adrenergic, meaning that norepinephrine (NE) is released. WebbSecond, retrograde activation of a postganglionic nerve trunk, the iCN, in TH WT mice commonly evoked rACs and eEPSCs (88% of cells) consistent with the activation of the postganglionic axon of the recorded neuron as well as eEPSCs arriving indirectly via activation of other SG neurons. iCN-evoked eEPSCs were rare in TH ChAT KO mice (8% …

Parasympathetic neurons are responsible for releasing norepinephrine on the target organ, while sympathetic neurons are responsible for releasing acetylcholine. Webb尼斯小體（英語： Nissl body ）是神經元內的一種大型顆粒，這些顆粒為帶有核糖體粗糙型內質網，是蛋白質合成的地方 。 此種顆粒以德國神經科學家弗朗茨·尼氏之名命名 。. 利用尼氏所發展出的選擇性染色法可以染出尼斯小體，尼氏染色使用苯胺標定核外RNA顆粒。 WebbThe postganglionic parasympathetic fibers then project to the smooth muscle of the iris to control pupillary size. In the upper medulla, the salivatory nuclei contain neurons with axons that project through the facial and glossopharyngeal nerves to ganglia that control salivary glands. glen rock district calendar
