It outlines the main divisions—central nervous system (brain and spinal cord) and peripheral nervous system (nerves extending from the CNS). The central nervous system is broken into forebrain, brainstem (midbrain, pons, medulla oblongata), and cerebellum, followed by the spinal cord’s signal pathways and reflexes. The peripheral nervous system is organized into somatic and autonomic divisions, including sympathetic “fight-or-flight” and parasympathetic “rest-and-digest,” and shows how sensory input, CNS processing, and motor output connect.",{"@graph":63,"@context":119},[64,80,102],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":51,"@type":70,"position":76},"https://docshare.wps.com/template/general/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/divisions-of-the-nervous-system-summary/571231/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/divisions-of-the-nervous-system-summary/571231.png","ImageObject",442,249,{"name":88,"@type":89},"Himbo","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-25","2026-10-13",true,{"@type":98,"interactionType":99,"userInteractionCount":101},"InteractionCounter",{"@type":100},"ViewAction",7,{"@type":103,"mainEntity":104},"FAQPage",[105,111,115],{"name":106,"@type":107,"acceptedAnswer":108},"What are the main divisions of the nervous system?","Question",{"text":109,"@type":110},"The nervous system has two main divisions: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
