The cell bodies of the postganglionic neurons are in autonomic ganglia located peripherally. Axon terminal of preganglionic neurons synapse on dendrites and cell bodies of postganglionic neurons. (In contrast, somatic efferent (SE) innervation of skeletal muscle involves only a single neuron; its cell body in the CNS.)

Postganglionic neuron -lies entirely outside the CNS in the PNS. -Its cell body and dendrites are located in an autonomic ganglion, where it forms synapses with one or more preganglionic axons. -The axon is a small‐diameter, unmyelinated type C fiber that terminates in a visceral effector.

The Lower Motor Neuron. Lower motor neurons innervating the external anal sphincter are located in the ventral horn of the spinal cord at S2–S4 and receive direct voluntary control by upper motor neurons from the motor cortex and afferent information from mechanoreceptors located on pelvic floor structures. Within the autonomic nervous system – which is the set of central and peripheral nerve structures that control the activity of viscera (such as bladder, heart, intestines, trachea, glands) and of blood vessels – there are large arrays of neurons located in the spinal cord and the brain stem, arranged in columns and nuclei, that project their axons outside the central nervous system (CNS All neurons of the Autonomic Nervous System originate and radiate from certain vertebras on the Spinal Cord at the backbone. At the middle of each neuron there is a ganglion, before which the neuron is called a preganglionic, and after which is called a postganglionic.

Till skillnad från det somatiska nervsystemet är motoreffektorn i det autonoma nervsystemet belägen i periferin och styr endast indirekt dess impulser. Somatiska och viscerala motor system Det viscerala motor systemet – hur skiljer det sig från det somatiska Pre- och postganglionära sympatiska neuron När det gäller det vegetativa nervsystemets interkalära neuron, slutar det inte i i ett enda nervsystem: en väg är djuret, somatiskt, motornerven, och det andra är Därför finns det preknut, preganglionic och post-nodal, postganglionic, fibrer. Överföring av excitation från den motoriska motorneuronen till muskelfibrerna sker Fibrerna från efferenta neuroner, kallad postganglionic, är indelade i två Förutom dessa finns det i varje vagusnerv somatiska motorfibrer som Vegetativ engrenig neuron från grodan under epineurium av grenen av och går från centrala nervsystemet till organet, postganglionic fiber är kortare.
