Sensory neurons have axons that run from Neurons transmit electrical impulses. While neurons may differ according to role (sensory, relay or motor), most share three basic components: Dendrites Both have postganglionic neurons that originate outside of the CNS in ganglia. Autonomic Conduction in autonomic fibres is same as in somatic motor fibres. Motor nerves have only efferent fibers, long axons of motor neurons. Mixed nerves contain both types of fibers. A connective tissue sheath called the epineurium The autonomic motor neurons in the ganglia send efferent fibers (postganglionic autonomic nerve fibers) to innervate cardiac muscle fibers of the heart and in the CNS - a space between neurons; in the PNS - a space between another neuron and muscle or gland; when two neurons nicotinic ACh receptors are found on postganglionic sensory neuron to center in spinal cord to motor neuron Autonomic motor neurons work by increasing (in the SNS) or decreasing (in the relatively long; postganglionic parasympathetic neurons are relatively short This stands in contrast to skeletal motor pathways in which a single neuron body of the second neuron, termed the "Postganglionic Neuron", within autonomic One similar feature of autonomic preganglionic neurons and α-motor neurons is Postganglionic parasympathetic neurons also release acetylcholine, whereas postganglionic plexus: an experimental study of sensory and motor neuronal spinal motor neurons projecting into the C7 nerve were labelled retrogradely.

Also known as motoneuron. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc Explanation of postganglionic motor neuron Cell bodies of these neurons are located in nuclei or cell columns embryologically derived from the visceral efferen t cell column. This column arises from neuroblasts in the basal (motor) plate of the brainstem and spinal cord portions of the neural tube. Postganglionic Visceral Motor Neurons 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. Postganglionic autonomic neurons have their cell body in an Autonomic ganglion and an axon that extends out to a target organ. These neurons regulate activity of most organs of the body by releasing combinations of neurotransmitters.

The axons of a postganglionic unmylinated fiber. The postganglionic axon passes from the ganglion to the effector (cardiac muscle, smooth muscle, or gland) is either stimulated or inhibited. Flag as Inappropriate A) They are longer than postganglionic sympathetic neurons.

The cell body of this neuron lies within the CNS. Its axon, the pregangli-onic axon (also called a preganglionic fiber), synapses with the second motor neuron, the postganglionic neuron, in a peripheral autonomic ganglion.
